The host cells take up the DNA, express the antigen, and present it to the immune system in a manner similar to that which would occur during natural infection. This induces humoral and cellular immune responses against the encoded antigens. The vector is called naked DNA because there is no need for complex formulations or delivery agents; the plasmid is injected in saline or other buffers.

Delivery of medications through the nasal mucosa.
Cell-surface components or appendages of bacteria that facilitate adhesion (BACTERIAL ADHESION) to other cells or to inanimate surfaces. Most fimbriae (FIMBRIAE, BACTERIAL) of gram-negative bacteria function as adhesins, but in many cases it is a minor subunit protein at the tip of the fimbriae that is the actual adhesin. In gram-positive bacteria, a protein or polysaccharide surface layer serves as the specific adhesin. What is sometimes called polymeric adhesin (BIOFILMS) is distinct from protein adhesin.
The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B.
Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.
Vaccines or candidate vaccines used to prevent infection with NEISSERIA MENINGITIDIS.

Role of antibodies against Bordetella pertussis virulence factors in adherence of Bordetella pertussis and Bordetella parapertussis to human bronchial epithelial cells. (1/496)

Immunization with whole-cell pertussis vaccines (WCV) containing heat-killed Bordetella pertussis cells and with acellular vaccines containing genetically or chemically detoxified pertussis toxin (PT) in combination with filamentous hemagglutinin (FHA), pertactin (Prn), or fimbriae confers protection in humans and animals against B. pertussis infection. In an earlier study we demonstrated that FHA is involved in the adherence of these bacteria to human bronchial epithelial cells. In the present study we investigated whether mouse antibodies directed against B. pertussis FHA, PTg, Prn, and fimbriae, or against two other surface molecules, lipopolysaccharide (LPS) and the 40-kDa outer membrane porin protein (OMP), that are not involved in bacterial adherence, were able to block adherence of B. pertussis and B. parapertussis to human bronchial epithelial cells. All antibodies studied inhibited the adherence of B. pertussis to these epithelial cells and were equally effective in this respect. Only antibodies against LPS and 40-kDa OMP affected the adherence of B. parapertussis to epithelial cells. We conclude that antibodies which recognize surface structures on B. pertussis or on B. parapertussis can inhibit adherence of the bacteria to bronchial epithelial cells, irrespective whether these structures play a role in adherence of the bacteria to these cells.  (+info)

Early childhood infection and atopic disorder. (2/496)

BACKGROUND: Atopy is of complex origins but the recent rise in atopic diseases in westernized communities points to the action of important environmental effects. One candidate mechanism is the changing pattern of microbial exposure in childhood. This epidemiological study investigated the relationship between childhood infections and subsequent atopic disease, taking into account a range of social and medical variables. METHODS: A total of 1934 subjects representing a retrospective 1975-84 birth group at a family doctor practice in Oxfordshire were studied. Public health and practice records were reviewed; temporal records were made of all diagnoses of infections and their treatments, all immunisations, and diagnoses of asthma, hay fever and eczema; maternal atopy and a number of other variables were documented. RESULTS: Logistic regression analysis identified three statistically significant predictors of subsequent atopic disease: maternal atopy (1.97, 95% CI 1.46 to 2.66, p < 0.0001), immunisation with whole-cell pertussis vaccine (1.76, 95% CI 1.39 to 2.23, p < 0.0001), and treatment with oral antibiotics in the first two years of life (2.07, 95% CI 1.64 to 2.60, p < 0.0001). There was no significant association found for maternal smoking, bottle feeding, sibship size, or social class. CONCLUSIONS: The prediction of atopic disease by maternal atopy mainly reflects the effect of acknowledged genetic factors. Interpretation of the prediction of atopic disorders by immunisation with wholecell pertussis vaccine and treatment with oral antibiotics needs to be very cautious because of the possibilities of confounding effects and reverse causation. However, plausible immune mechanisms are identifiable for the promotion of atopic disorders by both factors and further investigation of these association is warranted.  (+info)

Serum IgG antibody responses to pertussis toxin and filamentous hemagglutinin in nonvaccinated and vaccinated children and adults with pertussis. (3/496)

Levels of IgG antibody to pertussis toxin (PT) and filamentous hemagglutinin (FHA) were measured in paired serum samples from 781 patients fulfilling at least one laboratory criterion for pertussis that was suggested by an ad hoc committee sponsored by the World Health Organization. The patients were participants or family members of participants in a double-blind efficacy trial of a monocomponent pertussis toxoid vaccine. Of 596 nonvaccinated children, 90% had significant (two-fold or more) rises in PT IgG and FHA IgG levels. Only 17 (32%) of 53 children previously vaccinated with three doses of pertussis toxoid had rises in PT IgG levels because they already had elevated PT IgG levels in their acute-phase serum samples. PT IgG and FHA IgG levels were significantly higher in acute-phase serum samples from 29 adults than in acute-phase serum samples from the nonvaccinated children. Nevertheless, significant rises in levels of PT IgG (79% of samples) and FHA IgG (90%) were demonstrated in adults. In conclusion, assay of PT IgG and FHA IgG in paired serum samples is highly sensitive for diagnosing pertussis in nonvaccinated individuals. Assay of PT IgG levels in paired sera is significantly less sensitive for diagnosis of pertussis for children vaccinated with pertussis toxoid.  (+info)

Capture-recapture method for estimating misclassification errors: application to the measurement of vaccine efficacy in randomized controlled trials. (4/496)

BACKGROUND: The measure of efficacy is optimally performed by randomized controlled trials. However, low specificity of the judgement criteria is known to bias toward lower estimation, while low sensitivity increases the required sample size. A common technique for ensuring good specificity without a drop in sensitivity is to use several diagnostic tests in parallel, with each of them being specific. This approach is similar to the more general situation of case-counting from multiple data sources, and this paper explores the application of the capture-recapture method for the analysis of the estimates of efficacy. METHOD: An illustration of this application is derived from a study on the efficacy of pertussis vaccines where the outcome was based on > or =21 days of cough confirmed by at least one of three criteria performed independently for each subject: bacteriology, serology, or epidemiological link. Log-linear methods were applied to these data considered as three sources of information. RESULTS: The best model considered the three simple effects and an interaction term between bacteriology and epidemiological linkage. Among the 801 children experiencing > or =21 days of cough, it was estimated that 93 cases were missed, leading to a corrected total of 413 confirmed cases. The relative vaccine efficacy estimated from the same model was 1.50 (95% confidence interval: 1.24-1.82), similar to the crude estimate of 1.59 and confirming better protection afforded by one of the two vaccines. CONCLUSION: This method allows supporting analysis to interpret primary estimates of vaccine efficacy.  (+info)

Pertussis vaccination and wheezing illnesses in young children: prospective cohort study. The Longitudinal Study of Pregnancy and Childhood Team. (5/496)

OBJECTIVES: To examine the relation between pertussis vaccination and the prevalence of wheezing illnesses in young children. DESIGN: Prospective cohort study. SETTING: Three former health districts comprising Avon Health Authority. SUBJECTS: 9444 of 14 138 children enrolled in the Avon longitudinal study of pregnancy and childhood and for whom data on wheezing symptoms, vaccination status, and 15 environmental and biological variables were available. MAIN OUTCOME MEASURES: Episodes of wheezing from birth to 6 months, 7-18 months, 19-30 months, and 31-42 months. These time periods were used to derive five categories of wheezing illness: early wheezing (not after 18 months); late onset wheezing (after 18 months); persistent wheezing (at every time period); recurrent wheezing (any combination of two or more episodes for each period); and intermittent wheezing (any combination of single episodes of reported wheezing). These categories were stratified according to parental self reported asthma or allergy. RESULTS: Unadjusted comparisons of the defined wheezing illnesses in vaccinated and non-vaccinated children showed no significant association between pertussis vaccination and any of the wheezing outcomes regardless of stratification for parental asthma or allergy. Wheeze was more common in non-vaccinated children at 18 months, and there was a tendency for late onset wheezing to be associated with non-vaccination in children whose parents did not have asthma, but this was not significant. After adjustment for environmental and biological variables, logistic regression analyses showed no significant increased relative risk for any of the wheezing outcomes in vaccinated children: early wheezing (0.99, 95% confidence interval 0.80 to 1.23), late onset wheezing (0.85, 0.69 to 1.05), persistent wheezing (0.91, 0.47 to 1.79), recurrent wheezing (0.96, 0.72 to 1.26), and intermittent wheezing (1.06, 0.81 to 1.37). CONCLUSIONS: No evidence was found that pertussis vaccination increases the risk of wheezing illnesses in young children. Further follow up of this population with objective measurement of allergy and bronchial responsiveness is planned to confirm these observations.  (+info)

Variation in the Bordetella pertussis virulence factors pertussis toxin and pertactin in vaccine strains and clinical isolates in Finland. (6/496)

There is evidence that pertussis is reemerging in vaccinated populations. We have proposed, and provided evidence for, one explanation for this phenomenon in The Netherlands: antigenic divergence between vaccine strains and circulating strains. Finland has a pertussis vaccination history very similar to that of The Netherlands, and yet there is no evidence for an increase in the incidence of pertussis to the extent that it was observed in The Netherlands. A comparison of the Bordetella pertussis strains circulating in the two countries may shed light on the differences in pertussis epidemiology. Here we investigated whether temporal changes had occurred in pertussis toxin and pertactin types produced by the Finnish B. pertussis population. We show that strains isolated before 1964 produced the same pertussis toxin and pertactin variants as the vaccine strains. However, these vaccine types were replaced in later years, and in the 1990s most strains were distinct from the vaccine strains with respect to the two proteins. These trends are similar to those found in the Dutch B. pertussis population. An interesting difference between the contemporary Finnish and Dutch B. pertussis populations was found in the frequencies of pertactin variants, possibly explaining the distinct epidemiology of pertussis in the two countries.  (+info)

A randomized clinical trial of acellular pertussis vaccines in healthy adults: dose-response comparisons of 5 vaccines and implications for booster immunization. (7/496)

The safety and immunogenicity of 5 acellular pertussis vaccines (ACVs) were compared in a multicenter, randomized, double-blind trial. A total of 481 healthy adults were given a single intramuscular booster dose of ACV or placebo. Three different dose levels were tested for 4 ACVs: full strength (the dose level proposed for infant immunization), one-third strength, and one-tenth strength. For 1 multicomponent vaccine, only the pertussis toxoid dose level varied. Minor injection site reactions were common and similar in frequency among vaccinated groups. Late-onset injection site reactions were seen in all ACV groups. Dose-related increases in mean antibody titers against vaccine antigens were seen after immunization with all ACVs. Antibody responses against antigens not known to be present in the vaccines were detected after immunization with 4/5 ACVs. Antibody levels fell significantly during the year after immunization. These data support evaluation of ACVs for broader use among adolescents and adults.  (+info)

Cell-mediated immune responses in four-year-old children after primary immunization with acellular pertussis vaccines. (8/496)

Cell-mediated immune (CMI) responses to Bordetella pertussis antigens (pertussis toxin [PT], pertactin [PRN], and filamentous hemagglutinin [FHA]) were assessed in 48-month-old recipients of acellular pertussis [aP] vaccines (either from Chiron-Biocine [aP-CB] or from SmithKline Beecham [aP-SB]) and compared to CMI responses to the same antigens at 7 months of age, i.e., 1 month after completion of the primary immunization cycle. None of the children enrolled in this study received any booster of pertussis vaccines or was affected by pertussis during the whole follow-up period. Overall, around 75% of 4-year-old children showed a CMI-positive response to at least one B. pertussis antigen, independently of the type of aP vaccine received, and the proportion of CMI responders were at least equal at 48 and 7 months of age. However, longitudinal examination of individual responses showed that from 20 (against PT) to 37% (against FHA) of CMI responders after primary immunization became negative at 48 months of age. This loss was more than compensated for by conversion to positive CMI responses, ranging from 36% against FHA to 69% against PRN, in other children who were CMI negative at 7 months of age. In 60 to 80% of these CMI converters, a lack of decline or even marked elevation of antibody (Ab) titers against B. pertussis antigens also occurred between 20 and 48 months of age. In particular, the frequency of seropositivity to PRN and FHA (but not to PT) was roughly three times higher in CMI converters than in nonconverters. The acquisition of CMI response to B. pertussis antigens in 48-month-old children was not associated with a greater frequency of coughing episodes lasting >/=7 days and was characterized by a prevalent type 1 cytokine profile, with high gamma interferon and low or no production of interleukin-5, reminiscent of cytokine patterns following immunization with whole-cell pertussis vaccine or natural infection. Our data imply that vaccination-induced systemic CMI may wane by 4 years of age but may be acquired or naturally boosted by symptomless or minor clinical infection by B. pertussis. This might explain, at least in part, the persistence of protection against typical pertussis in aP vaccine recipients despite a substantial waning of both Ab and CMI responses induced by the primary immunization.  (+info)

N2 - The histamine sensitization test is a widely used method for measuring the residual toxicity of pertussis toxin in acellular pertussis vaccines. Although it has been used as a routine assay for decades, the current protocols are difficult to standardize because the test results vary considerably and are based on several factors, including mouse strain, age and sex. In this study, we observed that mice of strains CD1, ddY and C57/BL6 were sufficiently sensitive to pertussis toxin among six mice strains tested and that aged male mice were more sensitive to pertussis toxin than younger or female mice. Using this animal model, we showed pertussis toxin dose-dependent responses in the two histamine ...
Swelling involving the entire thigh or upper arm has been reported after booster doses of different acellular pertussis vaccines. Swelling of the entire thigh was reported among recipients of a booster dose of JNIH-6 (a two-component acellular pertussis vaccine produced by Biken [Japan] and comparable to the acellular pertussis component contained in Tripedia). During a study performed in Sweden during the 1980s, children who had previously received two or three doses of Biken acellular pertussis vaccine at age 6--8 months received a booster dose deep subcutaneously of the same vaccine at age 2 years. Certain children experienced substantial local reactions, including swelling of the entire thigh (16), although administration of vaccine subcutaneously could have influenced reaction rates in that study. Occurrence of extensive swelling involving the entire thigh of vaccinated children was reported among DTaP recipients in an open-label safety study in Germany during April 1993--November 1994, in ...

ISSN 1678-9946. http://dx.doi.org/10.1590/S0036-46652009000300002.. Objective: to discuss the current PAHO recommendation that does not support the substitution of traditional cellular DTP vaccine by acellular DTP, and the role of mutations, in humans, as the main cause of rare adverse events, such as epileptic-like convulsions, triggered by pertussis vaccine. Data review: the main components related to toxic effects of cellular pertussis vaccines are the lipopolysaccharide of bacterial cell wall and pertussis toxin. The removal of part of lipopolysaccharide layer has allowed the creation of a safer cellular pertussis vaccine, with costs comparable to the traditional cellular vaccine, and which may be a substitute for the acellular vaccine. Conclusion: The new methodology introduced by Instituto Butantan allows for the ...
Reassessment of the role of whole-cell pertussis vaccine as a cause of permanent neurologic damage is necessitated by the 10-year follow-up of the National Childhood Encephalopathy Study (NCES) in Great Britain. The findings of this study demonstrate that infants and young children with serious acute neurologic disorders are at an increased risk of later neurologic impairment or death, irrespective of the initial precipitating event. The results, however, do not establish a causal relationship between pertussis vaccination and chronic neurologic abnormalities. The Academy reaffirms its earlier conclusion that whole-cell pertussis vaccine has not been proven to be a cause of brain damage and continues to recommend pertussis vaccination in accordance with the guidelines in the 1994 Red Book.. ...

Like other vaccines, its not recommended for the first trimester, since this is the most critical time in fetal development when all of the major organs are developing and the risk for birth defects is the highest. There is no evidence that giving pregnant women the pertussis vaccine is harmful, since the vaccine is made of an inactivated (or killed ) virus.. (It is not recommended that pregnant women receive a vaccine with a live virus. For example, the measles-mumps-rubella (MMR) vaccine should never be given to pregnant women, since it contains live viruses and may potentially harm the developing baby.). The CDC does have one concern regarding pregnant women and the pertussis vaccine. The mothers antibodies may interfere with the babys immune response to the infant doses of pertussis vaccine, which are administered at 2 months, 4 months, and six months. There is a possibility that this leaves the baby less protected against ...
The effect of an extract of histamine-sensitizing factor (HSF) of Bordetella pertussis on the immune response of different strains of mice to ovalbumin (OA) was investigated with regard to optimal dose of antigen and adjuvant. It was observed that all strains of mice treated with HSF during immunization with OA demonstrated enhanced production of hemagglutinating antibodies, as compared to animals treated with antigen alone. This enhancement was generally not as great as that demonstrated when Al(OH)3 was the adjuvant. HSF also stimulated a reaginic antibody response (IgE) to OA, but not in all strains of mice. In reagin responders optimal responses were observed with high doses of both antigen and adjuvant, whereas low doses of both produced little or no response. Maximal reagin production occurred usually 14-28 days after immunization and persisted for long periods of time. An anamnestic reagin response was elicited upon secondary immunization with antigen alone, not only in mice immunized ...
Although the conventional Bordetella pertussis vaccine, which consists of killed whole organisms, has been shown to be effective in preventing disease, it has been associated with transient local and systemic reactions and may produce encephalopathy, though rarely. A new acellular pertussis vaccine …
In the 1990s, the US replaced whole cell pertussis vaccines with acellular pertussis vaccines over safety concerns. A research letter to Journal of the American Medical Association reports that the switch might be responsible for a recent rising number of pertussis cases (whooping cough) in children. Compared with whole cell...
Since their introduction in the 1940s and 1950s, pertussis vaccines (mostly in combination with diphtheria and tetanus toxoids as diphtheria, tetanus, and pertussis vaccines) have been very efficient in reducing pertussis mortality and morbidity in infants and young children. WHO estimates suggest that between 1999 and 2014, more than 100 000 infant deaths could have been averted mainly by increased coverage of pertussis vaccination.1 Pertussis vaccines come in two varieties: one is made of whole-cell killed Bordetella pertussis cells, consequently called whole-cell pertussis vaccine, and the other is made from one to five purified and partly chemically inactivated bacterial virulence factors, consequently called acellular pertussis vaccine. ...
Background: Pertussis is a vaccine-preventable respiratory infection caused by Bordetella pertussis. Since the 1980s, there has been a steady increase in the number of reported cases of pertussis in the United States. Advisory Committee on Immunization Practices (ACIP) recommends that all Health Care Workers (HCWs) who have not received or are unsure of the status of their pertussis vaccination , should receive a dose of Tdap as soon as feasible. There is scant data regarding pertussis vaccination status of HCWs and compliance with current ACIP recommendations. Methods: A survey questionnaire was created and validated to assess the knowledge, attitude and practices regarding Pertussis vaccination. The survey was conducted among all the HCWs in a Transplant Center at a tertiary care suburban New York hospital. This paper based survey questionnaire was distributed to all the HCWs in September 2016. Results: A total of 139 transplant HCWs were surveyed with a response rate of 100%. Only 53/139 ...
Pertussis Vaccine: A suspension of killed Bordetella pertussis organisms, used for immunization against pertussis (WHOOPING COUGH). It is generally used in a mixture with diphtheria and tetanus toxoids (DTP). There is an acellular pertussis vaccine prepared from the purified antigenic components of Bordetella pertussis, which causes fewer adverse reactions than whole-cell vaccine and, like the whole-cell vaccine, is generally used in a mixture with diphtheria and tetanus toxoids.

Introduction The routine use of the whole-cell pertussis vaccine has led to a significant reduction in the incidence of the disease in various countries around the world, with a reduction in morbidity and mortality. However, infants up to six months who did not receive the basic vaccination scheme remain susceptible and, when infected by Bordetella pertussis, may present atypical symptoms when compared with older children.1. Over the past few years there have been several reports concerning the severity of pertussis in infants, such as the nine cases reported in the United Kingdom by Smith & Vyas,1 of which six led to death. Severe complications were observed, such as apnea, seizures, respiratory insufficiency, arterial hypotension, pulmonary hypertension, pneumothorax, and secondary bacterial infections.. More recently, another study conducted in the United Kingdom showed that among the 142 infants under five months of age who were hospitalized with a clinical condition of severe respiratory ...
This study is the first descriptive epidemiologic study of a large case series of children with HHE. From July 31, 1996, when the first acellular pertussis vaccine was licensed for infants in the United States, to the end of our study period (December 31, 1998), acellular pertussis vaccines became the predominant pertussis-containing vaccines in the United States. During the time of our study (1996-1998), pertussis vaccination coverage rates were stable.11Concurrently, numbers of HHE reports to VAERS decreased from 99 in 1996 to 38 in 1998. This decrease could suggest that HHE occurs less frequently after vaccination with DTaP than after whole-cell pertussis, which is similar to what has been observed in clinical trials with respect to more common adverse events, such as injection site reactions, fever, and fussiness.12-16 Our finding of a decrease in HHE during a time of increasing DTaP usage is consistent with a summary by Heijbel et al4 of HHE rates in 8 pertussis vaccine studies; however, ...
Pertussis, whooping cough, caused by the gram negative pleomorphic bacillus, Bordetella pertussis, is a highly contagious, potentially life-threatening respiratory illness that has re-emerged in the United States (US) as a cause of morbidity and mortality in infants less than 6 months of age as well as morbidity in adolescents and adults. Tetanus toxoid, reduced diphtheria toxoid and acellular pertussis vaccine adsorbed (Tdap) immunization of women in the third trimester of pregnancy represents an opportunity to protect the vulnerable very young infants through passively acquired maternal pertussis specific antibodies. Tdap vaccine is being evaluated for this purpose since there is no monovalent acellular pertussis (aP) vaccine available in the U.S. This is a multi-site, randomized, double masked, cross-over study in 48 healthy pregnant women, 18-45 years of age who will be randomized (2:1) into two groups. One group will receive a single dose of Tdap vaccine at 30-32 weeks of gestation and a ...
Im willing to bet that …. When your dogs daycare, training facility or kennel asks for a kennel cough vaccine, you vaccinate your dog … am I right?. And why wouldnt you? You want to protect your dog (and other dogs) from illness and you trust your vet or daycare provider to have your dogs best interests at heart, like any caring dog lover would.. But Im here to tell you some things that will make you question whether the kennel cough vaccines your dog has been getting are actually in his best interests… or all just a lie.. What You Should Know About The Kennel Cough Vaccine. Bordetella, also known as kennel cough, is a vaccine thats been required by groomers, boarding kennels, training facilities and veterinary hospitals for years. Its become a routine requirement for any dog that spends time with other dogs (which is nearly all dogs).. The fact that a vaccine exists is surprising in itself. Kennel cough is almost always a self limiting disease thats about as dangerous to your dog ...
The introduction of whole-cell vaccines consisting of inactivated Bordetella pertussis organisms in the United States in the 1940s caused a precipitous decrease in pertussis incidence (27). However, over the past 30 y, pertussis has resurged in the United States. The resurgence began during the wP vaccine era, but the pace has quickened since aP vaccines were recommended for all primary and booster doses (11). This correlation has led many to hypothesize that aP vaccines are less effective on a population scale than the wP vaccines they replaced (10, 12, 13). Consistent with this notion, several recent observational studies concluded that children primed with aP vaccine had a twofold to fivefold greater risk of pertussis diagnosis compared with wP-primed children (19⇓⇓-22). Our results in nonhuman primates add to these findings by showing that animals vaccinated with wP cleared infection by a direct challenge twice as fast as animals vaccinated with aP. However, neither vaccine was able to ...
Despite an increased proportion of Bordetella pertussis isolates lacking pertactin, vaccine effectiveness (VE) is still high in Vermont for the five-dose diphtheria, tetanus, and acellular pertussis vaccine (DTaP) series and the tetanus, diphtheria, and acellular pertussis vaccine (Tdap).
Medical journals reported death and brain damage right after the pertussis vaccine began to be used. Yet there is lots of controversy. Why?
Before Canadas public pertussis vaccine program, incidence of the disease averaged 156 cases per 100 000 people. In contrast, with a vaccination program, the number of new cases ranged from 2 per 100 000 in 2011 to 13.9 in 2012. Most cases are in under-immunized populations. The current whooping cough vaccine (an acellular vaccine) has been used in Canada since 1997 and is also used in the rest of North America, Australia, New Zealand and much of Europe. The whole-cell vaccine was discontinued in North America because of adverse reactions in children, which included soreness at the injection site and fevers. The current study analyzed public health laboratory data linked with population-level vaccination data for a total of 5867 people born between 1992 and 2013, with 486 individuals testing positive for pertussis and the remaining 5381 testing negative. The researchers found that immunity was high during the first three years after vaccination but there was little protection after seven ...
The European Pharmacopoeia (Ph. Eur.) Commission is seeking public feedback on its proposal to replace the Histamine sensitisation test in mice (HIST) with a standardised CHO cell clustering assay for residual pertussis toxin testing, in general chapter 2.6.33 Residual pertussis toxin and irreversibility of pertussis toxoid and in ten individual monographs on vaccines containing acellular pertussis.. Published in the April 2018 issue of Pharmeuropa, this consultation will run until June 2018. Interested parties are invited to provide their comments through the Procedure for commenting on Pharmeuropa drafts.. ...
Tetanus, diphtheria, and pertussis are serious diseases caused by bacteria.. Tetanus (lockjaw) causes painful tightening of the muscles, usually all over the body. It can lead to locking of the jaw so the victim cannot open the mouth or swallow. Tetanus leads to death in about 1 out of 10 cases.. Diphtheria causes a thick coating in the nose, throat, and airways. It can lead to breathing problems, paralysis, heart failure, or death.. Pertussis (whooping cough) causes coughing so severe that it interferes with eating, drinking, or breathing. These spells can last for weeks and can lead to pneumonia, seizures (convulsions), brain damage, and death.. Diphtheria and pertussis are spread from person to person. Tetanus enters the body through a cut or wound.. The diphtheria, tetanus acellular, and pertussis adult vaccine (also called Tdap) is used to help prevent these diseases in people who are at least 10 years old. Most people in this age group require only one Tdap shot for protection against ...
Dr. Diamond responded: Ingredients. The acellular pertussis vaccines is now recommended to be given at least once to all adults . There is no recommendation for more than 1 adult booster, but i would not be surprised to see it given for every booster (7-10 yrs) in the future.The other differences are related to the specific type of antigens and quatity in each vaccine.Antigens are the material that triggers your immunity.
Pertussis Vaccine Market is driven by high birth rate, increase in number of geriatric population, government initiatives, growth in adoption of pertussis vaccination, and government insurance and reimbursement
Health care environments have been the setting for a number of pertussis outbreaks. Health care workers are at risk for occupational infections with pertussis and at risk for inadvertently transmitting pertussis to vulnerable patients, particularly the very young. An acellular pertussis vaccine (Tdap) was approved in 2005 by the US Food and Drug Administration for adults and adolescents, and recommendations from the US Centers for Disease Control and Preventions Advisory Committee on Immunization Practices (ACIP) call for its administration to the general population and, as soon as feasible, to health care personnel who work in hospitals or ambulatory care settings and have direct patient contact. ACOEM continues its support of that recommendation based on current knowledge of the epidemiology of pertussis, its transmission characteristics, documented risk in patient care settings, and efficacy of the Tdap vaccine ...

The practice of vaccination has a varied history ranging from successful eradication of smallpox to public concerns about adverse effects of vaccines. When concerns are raised about the adverse effects of vaccination, it is important to undertake a thorough investigation to either refute concerns (as in the case of the proposed links between measles vaccine and inflammatory bowel disease9 or between influenza vaccine and lung function10) or to describe accurately the magnitude of the adverse effect.. The tendency for pertussis antigens to stimulate IgE antibody responses has been well documented. What has been unclear is whether this effect is more pronounced after natural infection or after vaccination 11 12 and whether it is clinically important. Our study is the first to examine the postulated links between pertussis vaccination and wheezing illness in young children after controlling for potential confounding factors. Our key finding was the absence of any difference in the adjusted ...

Im a mom trying to keep my kids healthy, but I also have access to so much information that I can then go through it all and make it easier for people to understand. Youre talking about an illness that doesnt have to exist. The only way to help fight against it is to get the vaccine, and thats a simple way, Gellar continued.. Whooping cough is on the rise in the U.S., with more than 41,000 cases developing in 2012, causing at least 18 deaths according to the CDC.. Gellar also stated this alarming statistic, Eighty percent of the children who came down with it, they can track it back to a family member that brought it in, and 50 percent were the actual parents. I know theres nothing worse as a new parent than you thinking that you got your child sick…Its a simple vaccination for an adult to get every five years, and thats it. Its the only safe way to prevent the child from getting the disease.. Gellar said it is important for adults to get the pertussis vaccine to protect babies ...

Michael Harper for redOrbit.com - Your Universe Online. In the early years of life, children are given immunization shots against all types of potential dangerous illness, including whooping cough, or acellular pertussis. According to a new study, however, children older than 6 and even some teenagers could benefit from an extra round of booster shots.. We found that the effectiveness of the vaccine wanes 42% on average each year during the five years after the fifth dose, said Dr. Nicola Klein, lead author of a study concerning the effectiveness of the whooping cough vaccine. This study was published in today´s New England Journal of Medicine.. Without a longer-lasting vaccine available, Dr. Klein suggests parents should continue to vaccinate their children saying, parents should know that some protection is better than no protection.. Dr. Klein and her team were the first to study such a large population of children who had received the diphtheria, tetanus, acellular pertussis (or DTaP) ...
Conventional pertussis vaccine prepared from killed whole cell B. pertussis organisms has been in widespread use since the early 1950s. Despite marked reductions in the incidence of pertussis, the use of the vaccine has caused concern because of questions of significant adverse reactions. Whooping cough is not notifiable in South Africa, and there is consequently a paucity of hard data on efficacy; in addition few cases are proven. Incidence, prevalence, severity and transmission of the disease hence remain a matter of conjecture. In order to provide background information and determine baseline data for undertaking further studies, available clinical and epidemiological data on whooping cough (pertussis) in South Africa was collated. It was intended to compare the pattern of disease seen in this country with that known in other parts of the world. Clinical and epidemiological findings from 1525 whooping cough admissions (diagnosed on the basis of clinical criteria) obtained from 6 major ...

This review summarises the epidemiology and control of pertussis in England and Wales since the introduction of routine immunisation and considers the implications for future control. Routine infant immunisation with a whole-cell pertussis (wP) vaccine was introduced in 1957 and had a marked impact on the overall disease burden. Following a fall in vaccine coverage during the 1970s and 80s linked to a safety scare with wP vaccine, there was an extended period of high coverage and pertussis incidence fell dramatically. Incidence continued to decrease with the introduction of an acellular pertussis vaccine in the pre-school booster in November 2001 and in the primary United Kingdom (UK) schedule in September 2004 but has increased since July 2011. In response to a high rate of pertussis in infants, a temporary vaccination programme for pregnant women was introduced in October 2012. The key aim of the programme is to protect vulnerable infants from birth in the first months of life, before they can be

Pertussis vaccines are effective at preventing illness[40] and are recommended for routine use by the World Health Organization[41] and the Centers for Disease Control and Prevention.[42] The vaccine saved an estimated half a million lives in 2002.[41]. The multicomponent acellular pertussis vaccine is 71-85% effective, with greater effectiveness for more severe strains.[40] Despite widespread vaccination, however, pertussis has persisted in vaccinated populations and is today one of the most common vaccine-preventable diseases in Western countries.[43] The 21st-century resurgences in pertussis infections are attributed to a combination of waning immunity and bacterial mutations that elude vaccines.[43][44]. Immunization does not confer lifelong immunity; a 2011 CDC study indicated that protection may only last three to six years. This covers childhood, which is the time of greatest exposure and greatest risk of death from pertussis.[18][45]. An effect of widespread immunization on society has ...
Pertussis is an infection that causes severe coughing. The bacteria that causes the infection is called Bortella pertussis. Pertussis is called whooping cough because of the whoop-like sound that can be heard when someone who has is breathes in cold air. Pertussis typically starts with cold-like symptoms: a runny nose, mild fever, and a minor cough. After 1 to 2 weeks, the cough begins to get worse and lasts for many weeks. Sometimes the cough is so bad that one can throw up. A person catches pertussis if they come in close contact with another person who has it. A person who is infected with pertussis is most contagious during the first 2 weeks after the cough begins. Because the symptoms of pertussis in its early stage mimic a common cold, it is often not diagnosed or treated until more severe symptoms occur, putting many people at a high risk of infection. When a person who has pertussis sneezes or coughs, tiny droplets of bacteria (that one cant see) go into the air. People who are ...
Montgomery County Health Department today warns parents about the continued dangers of pertussis (whooping cough). Vaccinated mothers pass protective antibodies to their infants during pregnancy, said Mary Perez, Health Director. Right now, its estimated that fewer than half of all pregnant women in North Carolina are vaccinated against whooping cough. We need to increase that number to help improve the health of our children and of our communities.. All expecting mothers are urged to receive a pertussis vaccine (called Tdap because it covers tetanus, diphtheria, and pertussis). Prenatal vaccination will help protect newborn children until they are old enough to receive their own vaccination against pertussis. Because immunity decreases over time, women should receive the pertussis vaccine in the last trimester of each pregnancy.. Pertussis continues to spread across the nation. Disease rates and risks of hospitalization and death are highest for infants under the age of one. Pertussis can ...
