The relationship of an attribute to the disease is examined by comparing diseased and non-diseased persons with regard to the frequency or levels of the attribute in each group.Administration, Mucosal: Delivery of a drug or other substance into the body through the epithelium lining of MUCOUS MEMBRANE involved with absorption and secretion.Hemadsorption Inhibition Tests: Serological tests that measure anti-hemadsorption agents such as antiviral ANTIBODIES that block VIRAL HEMAGGLUNININS from adhering to the surface of red blood cells.Disease Models, Animal: Naturally occurring or experimentally induced animal diseases with pathological processes sufficiently similar to those of human diseases. They are used as study models for human diseases.Drug Storage: The process of keeping pharmaceutical products in an appropriate location.T-Lymphocytes: Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.Spain: Parliamentary democracy located between France on the northeast and Portugual on the west and bordered by the Atlantic Ocean and the Mediterranean Sea.Mice, Inbred C57BLViral Core Proteins: Proteins found mainly in icosahedral DNA and RNA viruses. They consist of proteins directly associated with the nucleic acid inside the NUCLEOCAPSID.Diphtheria-Tetanus-acellular Pertussis Vaccines: Combined vaccines consisting of DIPHTHERIA TOXOID; TETANUS TOXOID; and an acellular form of PERTUSSIS VACCINE. At least five different purified antigens of B. pertussis have been used in various combinations in these vaccines.RNA Replicase: An enzyme that catalyses RNA-template-directed extension of the 3'- end of an RNA strand by one nucleotide at a time, and can initiate a chain de novo. (Enzyme Nomenclature, 1992, p293)Communicable Disease Control: Programs of surveillance designed to prevent the transmission of disease by any means from person to person or from animal to man.Clinical Trials as Topic: Works about pre-planned studies of the safety, efficacy, or optimum dosage schedule (if appropriate) of one or more diagnostic, therapeutic, or prophylactic drugs, devices, or techniques selected according to predetermined criteria of eligibility and observed for predefined evidence of favorable and unfavorable effects. This concept includes clinical trials conducted both in the U.S. and in other countries.Staphylococcal VaccinesSwine: Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).T-Lymphocytes, Cytotoxic: Immunized T-lymphocytes which can directly destroy appropriate target cells. These cytotoxic lymphocytes may be generated in vitro in mixed lymphocyte cultures (MLC), in vivo during a graft-versus-host (GVH) reaction, or after immunization with an allograft, tumor cell or virally transformed or chemically modified target cell. The lytic phenomenon is sometimes referred to as cell-mediated lympholysis (CML). These CD8-positive cells are distinct from NATURAL KILLER CELLS and NATURAL KILLER T-CELLS. There are two effector phenotypes: TC1 and TC2.Viral Nonstructural Proteins: Proteins encoded by a VIRAL GENOME that are produced in the organisms they infect, but not packaged into the VIRUS PARTICLES. Some of these proteins may play roles within the infected cell during VIRUS REPLICATION or act in regulation of virus replication or VIRUS ASSEMBLY.Vero Cells: A CELL LINE derived from the kidney of the African green (vervet) monkey, (CERCOPITHECUS AETHIOPS) used primarily in virus replication studies and plaque assays.Cytomegalovirus Vaccines: Vaccines or candidate vaccines used to prevent infection with CYTOMEGALOVIRUS.Licensure: The legal authority or formal permission from authorities to carry on certain activities which by law or regulation require such permission. It may be applied to licensure of institutions as well as individuals.Human Experimentation: The use of humans as investigational subjects.Anseriformes: An order of BIRDS comprising the waterfowl, particularly DUCKS; GEESE; swans; and screamers.Emulsions: Colloids formed by the combination of two immiscible liquids such as oil and water. Lipid-in-water emulsions are usually liquid, like milk or lotion. Water-in-lipid emulsions tend to be creams. The formation of emulsions may be aided by amphiphatic molecules that surround one component of the system to form MICELLES.Drug Industry: That segment of commercial enterprise devoted to the design, development, and manufacture of chemical products for use in the diagnosis and treatment of disease, disability, or other dysfunction, or to improve function.Incidence: The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from PREVALENCE, which refers to all cases, new or old, in the population at a given time.GeorgiaEpitopes, T-Lymphocyte: Antigenic determinants recognized and bound by the T-cell receptor. Epitopes recognized by the T-cell receptor are often located in the inner, unexposed side of the antigen, and become accessible to the T-cell receptors after proteolytic processing of the antigen.

Flu season: Flu season is an annually recurring time period characterized by the prevalence of outbreaks of influenza (flu). The season occurs during the cold half of the year in each hemisphere.Influenza A virus subtype H1N1: Influenza A (H1N1) virus is the subtype of influenza A virus that was the most common cause of human influenza (flu) in 2009, and is associated with the 1918 outbreak known as the Spanish Flu.Influenza Research Database: The Influenza Research Database (IRD)IRD Influenza Research Database BRCSquires, R.B.Influvac: Influvac is a sub-unit vaccine produced and marketed by Abbott Laboratories. It contains inactivated purified surface fragments (sub-units) from the three different strains of the influenza virus (A/H1N1, A/H3N2, and Influenza B Virus) that are selected and distributed by the World Health Organization, on the basis of their latest recommendations.Influenza A virus subtype H5N1: Influenza A virus subtype H5N1, also known as A(H5N1) or simply H5N1, is a subtype of the influenza A virus which can cause illness in humans and many other animal species. A bird-adapted strain of H5N1, called HPAI A(H5N1) for highly pathogenic avian influenza virus of type A of subtype H5N1, is the highly pathogenic causative agent of H5N1 flu, commonly known as avian influenza ("bird flu").Global spread of H5N1 in 2006: The global spread of (highly pathogenic) H5N1 in birds is considered a significant pandemic threat.Reverse vaccinology: Reverse vaccinology is an improvement on vaccinology that employs bioinformatics, pioneered by Rino Rappuoli and first used against Serogroup B meningococcus.Pizza et al.VaccinationPandemic: A pandemic (from Greek πᾶν pan "all" and δῆμος demos "people") is an epidemic of infectious disease that has spread through human populations across a large region; for instance multiple continents, or even worldwide. A widespread endemic disease that is stable in terms of how many people are getting sick from it is not a pandemic.Polysorbate: Polysorbates are a class of emulsifiers used in some pharmaceuticals and food preparation. They are often used in cosmetics to solubilize essential oils into water-based products.TwinrixPeptide vaccine: A peptide vaccine is any peptide which serves to immunize an organism against a pathogen. Peptide vaccine are often synthetic and mimic naturally occurring proteins from pathogens.SqualaneNaked DNA: Naked DNA is histone-free DNA that is passed from cell to cell during a gene transfer process called transformation or transfection. In transformation, purified or naked DNA is taken up by the recipient cell which will give the recipient cell a new characteristic or phenotype.Global Vaccines: Global Vaccines, Inc is a mission-driven non-profit company applying state-of-the-art science and innovative business strategies to design and develop affordable vaccines for people in poor countries.Immunization during pregnancy: Immunization during pregnancy, that is the administration of a vaccine to a pregnant woman, is not a routine event as it is generally preferred to administer vaccines either prior to conception or in the postpartum period. When widespread vaccination is used, the risk for an unvaccinated pregnant patient to be exposed to a related infection is low, allowing for postponement, in general, of routine vaccinations to the postpartum period.Four Seasons Baltimore and Residences: Four Seasons Hotel Baltimore is currently a 22 story highrise hotel complex building which opened on November 14, 2011. The building's construction began back in 2007 and went through several changes.Immunologic adjuvant: In immunology, an adjuvant is a component that potentiates the immune responses to an antigen and/or modulates it towards the desired immune responses. The word “adjuvant” comes from the Latin word adiuvare, meaning to help or aid.Newmarket, Suffolk: Newmarket is a market town in the English county of Suffolk, approximately 65 miles (105 kilometres) north of London. It is generally considered the birthplace and global centre of thoroughbred horse racing and a potential World Heritage Site.Nasal administrationHIV Vaccine Trials Network: The HIV Vaccine Trials Network (HVTN) is a non-profit organization which connects physicians and scientists with activists and community educators for the purpose of conducting clinical trials seeking a safe and effective HIV vaccine. Collaboratively, research professionals and laypeople review potential vaccines for safety, immune response, and efficacy.National Outbreak Reporting System: ==The National Outbreak Reporting System (NORS)==Neuraminidase inhibitor: Neuraminidase inhibitors are a class of drugs which block the neuraminidase enzyme. They are commonly used as antiviral drugs because they block the function of viral neuraminidases of the influenza virus, by preventing its reproduction by budding from the host cell.DPT vaccineInjection site reaction: Injection site reactions are allergic reactions that result in cutaneous necrosis that may occur at sites of medication injection, typically presenting in one of two forms, (1) those associated with intravenous infusion or (2) those related to intramuscular injection.James, William; Berger, Timothy; Elston, Dirk (2005).Conjugate vaccine: A conjugate vaccine is created by covalently attaching a poor (polysaccharide) antigen to a carrier protein (preferably from the same microorganism), thereby conferring the immunological attributes of the carrier to the attached antigen.Universal Immunization Programme: Universal Immunization Programme is a vaccination program launched by the Government of India in 1985. It became a part of Child Survival and Safe Motherhood Programme in 1992 and is currently one of the key areasWisconsin Alumni Research Foundation: The Wisconsin Alumni Research Foundation is the independent nonprofit technology transfer organization serving the University of Wisconsin–Madison and Morgridge Institute for Research. It provides significant research support, granting tens of millions of dollars to the university each year and contributing to the university's "margin of excellence.ImmunizationCervarixU.S.-Mexico Border Infectious Disease Surveillance Project: The U.S.OseltamivirFerret: The ferret (Mustela putorius furo) is the domesticated form of the European polecat, a mammal belonging to the same genus as the weasel, Mustela of the family Mustelidae.Harris & Yalden 2008, pp.Meningococcal vaccineBird trapping: Bird trapping techniques to capture wild birds include a wide range of techniques that have their origins in the hunting of birds for food. While hunting for food does not require birds to be caught alive, some trapping techniques capture birds without harming them and are of use in ornithology research.List of Parliamentary constituencies in Kent: The ceremonial county of Kent,AS04: AS04 (Aka. "Adjuvant System 04") is a trade name for combination of adjuvants used in various vaccine product by GlaxoSmithKline (GSK), in particular the Fendrix Hepatitis B vaccine.Plaque reduction neutralization test: The Plaque reduction neutralization test is used to quantify the titre of neutralising antibody for a virus.Virus-like particle: Virus-like particles resemble viruses, but are non-infectious because they do not contain any viral genetic material. The expression of viral structural proteins, such as Envelope or Capsid, can result in the self-assembly of virus like particles (VLPs).Pertussis vaccineDenise Faustman: Denise L. Faustman, (born 1958) is a U.Idiosyncratic drug reactionAntiviral drug: Antiviral drugs are a class of medication used specifically for treating viral infections. Like antibiotics for bacteria, specific antivirals are used for specific viruses.Cholera vaccineProportional reporting ratio: The proportional reporting ratio (PRR) is a statistic that is used to summarize the extent to which a particular adverse event is reported for individuals taking a specific drug, compared to the frequency at which the same adverse event is reported for patients taking some other drug (or who are taking any drug in a specified class of drugs). The PRR will typically be calculated using a surveillance database in which reports of adverse events from a variety of drugs are recorded.Influenza virus matrix protein 2: Matrix protein 2 of Influenza virus is a single-spanning transmembrane protein. It is expressed on the infected cell surface and incorporated into virions where it is a minor component.Kennel clubCD4 immunoadhesin: CD4 immunoadhesin is a recombinant fusion protein consisting of a combination of CD4 and the fragment crystallizable region.Georges Guillain: Georges Charles Guillain () (3 March 1876 - 29 June 1961) was a French neurologist born in Rouen.Typhoid vaccinePostmarketing surveillance: Postmarketing surveillance (PMS) (also post market surveillance) is the practice of monitoring the safety of a pharmaceutical drug or medical device after it has been released on the market and is an important part of the science of pharmacovigilance. Since drugs are approved on the basis of clinical trials, which involve relatively small numbers of people who have been selected for this purpose - meaning that they normally do not have other medical conditions which may exist in the general population - postmarketing surveillance can further refine, or confirm or deny, the safety of a drug after it is used in the general population by large numbers of people who have a wide variety of medical conditions.Smallpox demon: or smallpox devil is a demon which was believed to be responsible for causing smallpox in medieval Japan. In those days, people tried to appease the smallpox demon by assuaging his anger, or they tried to attack the demon since they had no other effective treatment for smallpox.Kalinite: Kalinite is a mineral composed of hydrated potassium aluminium sulfate (a type of alum). It is a fibrous monoclinic alum, distinct from isometric potassium alum,American Mineralogist (1923) 8:15 named in 1868.MVA85A: MVA85A (modified vaccinia Ankara 85A) is a new-generation vaccine against tuberculosis developed by researchers at Oxford University. This vaccine produces higher levels of long-lasting cellular immunity when used together with the older TB vaccine BCG.Viral pneumoniaCell-mediated immunity: Cell mediated immunity is an immune response that does not involve antibodies, but rather involves the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen. Historically, the immune system was separated into two branches: humoral immunity, for which the protective function of immunization could be found in the humor (cell-free bodily fluid or serum) and cellular immunity, for which the protective function of immunization was associated with cells.
(1/3234) Activity in saline of phthalylated or succinylated derivatives of mycobacterial water-soluble adjuvant.
A water-soluble fraction (WSA) of the cell wall can substitute for mycobacterial cells in Freund complete adjuvant. However, when WSA is administered in saline instead of in a water-in-oil emulsion, its adjuvant activity is very weak, and under certain experimental conditions it can even inhibit the humoral immune response. The data reported in the present study show that after treatment by phthalic or succinic anhydride the adjuvant activity of WSA was markedly changed, since high levels of circulating antibodies were produced when these derivatives were administered with an antigen in an aqueous medium. Moreover, the antigenic determinants of WSA were modified and acylated WSA had no tuberculin-like activity. (+info)
(2/3234) Immunoglobulin-specific radioimmunoprecipitation assays for quantitation of nasal secretory antibodies to hemagglutinin of type A influenza viruses.
Radioimmunoprecipitation (RIP) assays were developed to selectively quantitate class-specific antibodies to purified hemagglutinins (HA) of type A influenza virus in nasal secretions. Rabbit anti-human secretory piece of immunoglobulin A (IgA) and rabbit anti-human IgG were used as second antibodies. A third antibody, goat anti-rabbit IgG, was incorporated into the system to separate immune complexes formed between iodinated HA, nasal wash test specimen, and second antibody. The utilization of this reagent avoided the need for large quantities of IgA and IgG antibody-negative carrier secretions. Nasal was specimens obtained from 14 adults immunized with an inactivated type A influenza virus vaccine were evaluated by RIP and viral neutralization assays. Significant homologous postvaccination secretory IgA and IgG antibody levels were demonstrable in 13 (93%) of individuals by RIP, whereas only 5 (36%) exhibited rises by viral neutralization tests. Moreover, the geometric mean IgA and IgG antibody levels were at least 20- and 37-fold greater than the neutralizing antibody titer. The pattern of heterologous immunoglobulin-specific antibody responses tended to be similar to those observed with the homologous HA subunit. (+info)
(3/3234) Potential advantages of DNA immunization for influenza epidemic and pandemic planning.
Immunization with purified DNA is a powerful technique for inducing immune responses. The concept of DNA immunization involves insertion of the gene encoding the antigen of choice into a bacterial plasmid and injection of the plasmid into the host where the antigen is expressed and where it induces humoral and cellular immunity. The most effective routes and methods for DNA immunization are bombardment with particles coated with DNA ("gene gun" technique), followed by the intramuscular and intradermal routes. DNA immunization technology has the potential to induce immunity to all antigens that can be completely encoded in DNA, which therefore include all protein, but not carbohydrate, antigens. DNA immunization results in presentation of antigens to the host's immune system in a natural form, like that achieved with live-attenuated vaccines. The DNA immunization strategy has the potential to rapidly provide a new vaccine in the face of an emerging influenza pandemic. (+info)
(4/3234) Mucosal immunity to influenza without IgA: an IgA knockout mouse model.
IgA knockout mice (IgA-/-) were generated by gene targeting and were used to determine the role of IgA in protection against mucosal infection by influenza and the value of immunization for preferential induction of secretory IgA. Aerosol challenge of naive IgA-/- mice and their wild-type IgA+/+ littermates with sublethal and lethal doses of influenza virus resulted in similar levels of pulmonary virus infection and mortality. Intranasal and i.p. immunization with influenza vaccine plus cholera toxin/cholera toxin B induced significant mucosal and serum influenza hemagglutinin-specific IgA Abs in IgA+/+ (but not IgA-/-) mice as well as IgG and IgM Abs in both IgA-/- and IgA+/+ mice; both exhibited similar levels of pulmonary and nasal virus replication and mortality following a lethal influenza virus challenge. Monoclonal anti-hemagglutinin IgG1, IgG2a, IgM, and polymeric IgA Abs were equally effective in preventing influenza virus infection in IgA-/- mice. These results indicate that IgA is not required for prevention of influenza virus infection and disease. Indeed, while mucosal immunization for selective induction of IgA against influenza may constitute a useful approach for control of influenza and other respiratory viral infections, strategies that stimulate other Igs in addition may be more desirable.

(5/3234) Influenza vaccination among the elderly in Italy.
This article surveys the attitudes and perceptions of a random sample of the elderly population in three regions of Italy on the use and efficacy of influenza vaccine. The data were collected by direct interviews using a standard questionnaire. The results show that vaccination coverage against influenza is inadequate (26-48.6%). The major reasons for nonvaccination were lack of faith in the vaccine and disbelief that influenza is a dangerous illness. These data emphasize the need for a systematic education programme targeted at the elderly and the provision of influenza vaccination, with the increased cooperation of general practitioners. (+info)
(6/3234) Protection of mice against a lethal influenza virus challenge after immunization with yeast-derived secreted influenza virus hemagglutinin.
The A/Victoria/3/75 (H3N2-subtype) hemagglutinin (HA) gene was engineered for expression in Pichia pastoris as a soluble secreted molecule. The HA cDNA lacking the C-terminal transmembrane anchor-coding sequence was fused to the Saccharomyces cerevisiae alpha-mating factor secretion signal and placed under control of the methanol-inducible P. pastoris alcohol oxidase 1 (AOX1) promoter. Growth of transformants on methanol-containing medium resulted in the secretion of recombinant non-cleaved soluble hemagglutinin (HA0s). Remarkably, the pH of the induction medium had an important effect on the expression level, the highest level being obtained at pH 8.0. The gel filtration profile and the reactivity against a panel of different HA-conformation specific monoclonal antibodies indicated that HA0s was monomeric. Analysis of the N-linked glycans revealed a typical P. pastoris type of glycosylation, consisting of glycans with 10-12 glycosyl residues. Mice immunized with purified soluble hemagglutinin (HA0s) showed complete protection against a challenge with 10 LD50 of mouse-adapted homologous virus (X47), whereas all control mice succumbed. Heterologous challenge with X31 virus [A/Aichi/2/68 (H3N2-subtype)], resulted in significantly higher survival rates in the immunized group compared with the control group. These results, together with the safety, reliability and economic potential of P. pastoris, as well as the flexibility and fast adaptation of the expression system may allow development of an effective recombinant influenza vaccine.

(7/3234) Measuring the effects of reminders for outpatient influenza immunizations at the point of clinical opportunity.
OBJECTIVE: To evaluate the influence of computer-based reminders about influenza vaccination on the behavior of individual clinicians at each clinical opportunity. DESIGN: The authors conducted a prospective study of clinicians' influenza vaccination behavior over four years. Approximately one half of the clinicians in an internal medicine clinic used a computer-based patient record system (CPR users) that generated computer-based reminders. The other clinicians used traditional paper records (PR users). MEASUREMENTS: Each nonacute visit by a patient eligible for an influenza vaccination was considered an opportunity for intervention. Patients who had contraindications for vaccination were excluded. Compliance with the guideline was defined as documentation that a clinician ordered the vaccine, counseled the patient about the vaccine, offered the vaccine to a patient who declined it, or verified that the patient had received the vaccine elsewhere. The authors calculated the proportion of opportunities on which each clinician documented action in the CPR and PR user groups. RESULTS: The CPR and PR user groups had different baseline compliance rates (40.1 and 27.9 per cent, respectively; P<0.05). Both rates remained stable during a two-year baseline period (P = 0.34 and P = 0.47, respectively). The compliance rates in the CPR user group increased 78 per cent from baseline (P<0.001), whereas the rates for the PR user group did not change significantly (P = 0.18). CONCLUSIONS: Clinicians who used a CPR with reminders had higher rates of documentation of compliance with influenza-vaccination guidelines than did those who used a paper record. Measurements of individual clinician behavior at the point of each clinical opportunity can provide precise evaluation of interventions that are designed to improve compliance with guidelines.

(8/3234) Detection of intracellular antigen-specific cytokines in human T cell populations.
Determination of antigen-specific cytokine responses of T lymphocytes after vaccination is made difficult by the low frequency of responder cells. In order to detect these responses, the profile of intracellular cytokines was analyzed using flow cytometry after antigenic expansion. Peripheral blood mononuclear cells were stimulated with antigens for 5 days, further expanded with interleukin (IL)-2, and then restimulated on day 10. Cytokine production was detected by intracellular staining with monoclonal antibodies after saponin-based permeabilization. Influenza expansion resulted in specific interferon-gamma (IFN-gamma) production of 6%-20%, with less IL-4 production (0%-2%). Tetanus toxoid resulted in even greater production. IL-4 and IFN-gamma were produced mainly by memory cells of the CD45RO+ phenotype. IFN-gamma production was contributed by both CD4 and CD8 populations. These methods were then applied to a clinical trial of a candidate human immunodeficiency virus type 1 vaccine. Antigen-specific increases in IFN-gamma were measured, which corresponded to antibody production, lymphoproliferation, and skin testing. (+info)
