Immunoglobulin-specific radioimmunoprecipitation assays for quantitation of nasal secretory antibodies to hemagglutinin of type A influenza viruses. (1/2149)

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)

Expanded safety and immunogenicity of a bivalent, oral, attenuated cholera vaccine, CVD 103-HgR plus CVD 111, in United States military personnel stationed in Panama. (2/2149)

To provide optimum protection against classical and El Tor biotypes of Vibrio cholerae O1, a single-dose, oral cholera vaccine was developed by combining two live, attenuated vaccine strains, CVD 103-HgR (classical, Inaba) and CVD 111 (El Tor, Ogawa). The vaccines were formulated in a double-chamber sachet; one chamber contained lyophilized bacteria, and the other contained buffer. A total of 170 partially-immune American soldiers stationed in Panama received one of the following five formulations: (a) CVD 103-HgR at 10(8) CFU plus CVD 111 at 10(7) CFU, (b) CVD 103-HgR at 10(8) CFU plus CVD 111 at 10(6) CFU, (c) CVD 103-HgR alone at 10(8) CFU, (d) CVD 111 alone at 10(7) CFU, or (e) inactivated Escherichia coli placebo. Among those who received CVD 111 at the high or low dose either alone or in combination with CVD 103-HgR, 8 of 103 had diarrhea, defined as three or more liquid stools. None of the 32 volunteers who received CVD 103-HgR alone or the 35 placebo recipients had diarrhea. CVD 111 was detected in the stools of 46% of the 103 volunteers who received it. About 65% of all persons who received CVD 103-HgR either alone or in combination had a fourfold rise in Inaba vibriocidal titers. The postvaccination geometric mean titers were comparable among groups, ranging from 450 to 550. Ogawa vibriocidal titers were about twice as high in persons who received CVD 111 as in those who received CVD 103-HgR alone (600 versus 300). The addition of CVD 111 improved the overall seroconversion rate and doubled the serum Ogawa vibriocidal titers, suggesting that the combination of an El Tor and a classical cholera strain is desirable. While CVD 111 was previously found to be well tolerated in semiimmune Peruvians, the adverse effects observed in this study indicate that this strain requires further attenuation before it can be safely used in nonimmune populations.  (+info)

Long-lasting protection by live attenuated simian immunodeficiency virus in cynomolgus monkeys: no detection of reactivation after stimulation with a recall antigen. (3/2149)

The infection of cynomolgus monkeys with an attenuated simian immunodeficiency virus (SIV) (C8) carrying a deletion in the nef gene results in a persistent infection associated with an extremely low viral burden in peripheral blood mononuclear cells. The aim of this study was to determine (1) the breadth of the protection after repeated challenges of monkeys with SIV homologous strains of different pathogenicity, (2) the genotypic stability of the live virus vaccine, (3) whether the protection might depend on cellular resistance to superinfection, and (4) whether immunogenic stimuli such as recall antigens could reactivate the replication of the C8 virus. To address these goals, the monkeys were challenged at 40 weeks after C8 infection with 50 MID50 of cloned SIVmac251, BK28 grown on macaque cells. They were protected as indicated by several criteria, including virus isolation, anamnestic serological responses, and viral diagnostic PCR. At 92 weeks after the first challenge, unfractionated peripheral blood mononuclear cells from protected monkeys were susceptible to the in vitro infection with SIVmac32H, spl. At 143 weeks after C8 infection, the four protected monkeys were rechallenged with 50 MID50 of the pathogenic SIVmac32H, spl grown on macaque cells. Once again, they were protected. The C8 virus remained genotypically stable, and depletion of CD4(+) cells was not observed during approximately 3 years of follow-up. In contrast, it was found that the infection with SIVmac32H, spl induced CD4(+) cell depletion in three of three control monkeys. Of importance, stimulation with tetanus toxoid, although capable of inducing specific humoral and T cell proliferative responses, failed to induce a detectable reactivation of C8 virus.  (+info)

Detection of intracellular antigen-specific cytokines in human T cell populations. (4/2149)

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)

Recombinant influenza A virus vaccines for the pathogenic human A/Hong Kong/97 (H5N1) viruses. (5/2149)

Recombinant reassortment technology was used to prepare H5N1 influenza vaccine strains containing a modified hemagglutinin (HA) gene and neuraminidase gene from the A/Hong Kong/156/97 and A/Hong Kong/483/97 isolates and the internal genes from the attenuated cold-adapted A/Ann Arbor/6/60 influenza virus strain. The HA cleavage site (HA1/HA2) of each H5N1 isolate was modified to resemble that of "low-pathogenic" avian strains. Five of 6 basic amino acids at the cleavage site were deleted, and a threonine was added upstream of the remaining arginine. The H5 HA cleavage site modification resulted in the expected trypsin-dependent phenotype without altering the antigenic character of the H5 HA molecule. The temperature-sensitive and cold-adapted phenotype of the attenuated parent virus was maintained in the recombinant strains, and they grew to 108.5-9.4 EID50/mL in eggs. Both H5N1 vaccine virus strains were safe and immunogenic in ferrets and protected chickens against wild-type H5N1 virus challenge.  (+info)

Attenuated vesicular stomatitis viruses as vaccine vectors. (6/2149)

We showed previously that a single intranasal vaccination of mice with a recombinant vesicular stomatitis virus (VSV) expressing an influenza virus hemagglutinin (HA) protein provided complete protection from lethal challenge with influenza virus (A. Roberts, E. Kretzschmar, A. S. Perkins, J. Forman, R. Price, L. Buonocore, Y. Kawaoka, and J. K. Rose, J. Virol. 72:4704-4711, 1998). Because some pathogenesis was associated with the vector itself, in the present study we generated new VSV vectors expressing HA which are completely attenuated for pathogenesis in the mouse model. The first vector has a truncation of the cytoplasmic domain of the VSV G protein and expresses influenza virus HA (CT1-HA). This nonpathogenic vector provides complete protection from lethal influenza virus challenge after intranasal administration. A second vector with VSV G deleted and expressing HA (DeltaG-HA) is also protective and nonpathogenic and has the advantage of not inducing neutralizing antibodies to the vector itself.  (+info)

Protection against establishment of retroviral persistence by vaccination with a live attenuated virus. (7/2149)

Many human viruses not only cause acute diseases but also establish persistent infections. Such persistent viruses can cause chronic diseases or can reactivate to cause acute diseases in AIDS patients or patients receiving immunosuppressive therapies. While the prevention of persistent infections is an important consideration in the design of modern vaccines, surprisingly little is known about this aspect of protection. In the current study, we tested the feasibility of vaccine prevention of retroviral persistence by using a Friend virus model that we recently developed. In this model, persistent virus can be detected at very low levels by immunosuppressing the host to reactivate virus or by transferring persistently infected spleen cells into highly susceptible mice. Two vaccines were analyzed, a recombinant vaccinia virus vector expressing Friend virus envelope protein and a live attenuated Friend virus. Both vaccines reduced pathogenic virus loads to levels undetectable by infectious center assays. However, only the live, attenuated vaccine prevented immunosuppression-induced reactivation of persistent virus. Thus, even very low levels of persistent Friend virus posed a significant threat during immunosuppression. Our results demonstrate that vaccine protection against establishment of retroviral persistence is attainable.  (+info)

Immunization with a live, attenuated simian immunodeficiency virus vaccine leads to restriction of viral diversity in Rhesus macaques not protected from pathogenic challenge. (8/2149)

Rhesus macaques immunized with simian immunodeficiency virus SIVmac239Deltanef but not protected from SIVmac251 challenge were studied to determine the genetic and biological characteristics of the breakthrough viruses. Assessment of SIV genetic diversity (env V1-V2) revealed a reduction in the number of viral species in the immunized, unprotected macaques, compared to the number in nonimmunized controls. However, no evidence for selection of a specific V1-V2 genotype was observed, and biologically cloned isolates from the animals with breakthrough virus were similar with respect to replication kinetics and coreceptor use in vitro.  (+info)

Vaccination with live attenuated parasites has been shown to induce high level of protection against Toxoplasma gondii. In this study we compared the Mic1-3KO tachyzoite (a live attenuated strain) with the parental wild type (WT) tachyzoite in terms of virulence in mice in vivo, dissemination in mouse tissues and persistence in mouse brain. Survival of mice infected with the Mic1-3KO parasites correlated with reduced parasite burden in mouse tissues compared to the parental strain. Like the WT parasite, Mic1-3KO is able to form tissue cysts in vivo which are not, in our experimental conditions, infectious when given by oral route. Infection with the attenuated tachyzoite induced lower levels of cytokine and chemokine than with the parental strain. These data demonstrate that the deleted strain derived from a type I strain behaves like type II strain in outbred mice in terms of virulence, dissemination in mouse tissue and persistence in brain ...

Description: FluMist is prepared as a live, attenuated trivalent vaccine for administration by intranasal spray. The influenza virus strains in FluMist are cold-adapted which means that they grow efficiently at 25°C and restricted growth at temperatures of 37°-39°C. Specific pathogen-free (SPF) eggs are inoculated with each of the reassortant strains and incubated to allow vaccine virus replication. The allantoic fluid of these eggs is harvested, pooled and then clarified by filtration. Each pre-filled refrigerated FluMist sprayer contains a single 0.2 mL dose. Each 0.2 mL dose contains 10^6.5-7.5 FFU of live attenuated influenza virus reassortants of each of the three strains: A/California/7/2009 (H1N1), A/Perth/16/2009 (H3N2), and B/Brisbane/60/2008. Each 0.2 mL dose also contains 0.188 mg/dose monosodium glutamate, 2.00 mg/dose hydrolyzed porcine gelatin, 2.42 mg/dose arginine, 13.68 mg/dose sucrose, 2.26 mg/dose dibasic potassium phosphate, 0.96 mg/dose monobasic potassium phosphate, and ...

There are few studies that have examined the frequencies of epitope-specific CD4(+) T cells following the use of a highly effective vaccine, yet such data would potentially be of value for the development of novel vaccination strategies. In this study we tracked human epitope-specific CD4(+) T cell responses over time after immunisation with a live attenuated varicella zoster virus vaccine by MHC Class II tetrameric complexes and functional assays. We show that the peptide-specific responses reflect those against whole virus antigens, and are similar in both frequency and phenotype to those found in healthy volunteers, despite a highly attenuated and clinically inapparent infection.
Increasing evidence demonstrates that live attenuated vaccines can activate nonspecific immune cells to train leukocytes (the white blood cells of the immune system) to mount a more effective defense against unrelated infections. The researchers demonstrated in a laboratory that vaccination with a live attenuated fungal strain generated trained innate protection against lethal sepsis (blood poisoning) caused by a combination of disease-causing fungi and bacteria. The authors propose that the protection from an unrelated live attenuated vaccine is produced by long-lived myeloid-derived suppressor cells (MDSCs) previously reported to inhibit septic inflammation and mortality in several experimental models. They stress that this live attenuated MMR vaccine concept is NOT in any way suggested to be directed against COVID-19, but instead an immune preventive measure against the severe inflammatory symptoms of COVID-19. The use of childhood live attenuated vaccines such as MMR given to adults to ...

Author Summary We introduce a proposed intervention against infectious diseases that extends and optimizes the recognized benefit of transmissible immunization that occurs with live-attenuated vaccines such as Oral Polio Vaccine (OPV), the vaccine chosen for the worldwide polio eradication campaign. The intervention proposed here is based upon Therapeutic Interfering Particles (TIPs) that are engineered to replicate only in the presence of the wildtype pathogen and act to inhibit the growth of the pathogen. Therefore TIPs piggyback on the pathogen, leading to two important differences from live-attenuated vaccines: TIPs can only transmit from individuals already infected with wildtype pathogen, and TIPs could only revert to virulence in individuals already carrying the wild-type pathogen. Intriguingly, because TIPs spread between individuals using the same transmission routes as the pathogen, they automatically find their way to the populations at greatest risk of infection, thus circumventing the

Viruses are nonliving obligate intracellular parasites that utilize either DNA or RNA as their genetic material. A virus usually has a proteinaceous capsid studded with different glycoproteins, which facilitate entry into a host cell. The capsid itself protects the genetic material of the virus. Viruses are usually extremely species-specific, rarely infecting different species. Virus replication may be halted by antiviral medications such as aciclovir. Furthermore, vaccines, comprised of heat-killed or live attenuated viruses and/or antigens, may be injected into a host animal to provoke a humoral immune response. Antibodies produced will circulate and memory T/B cells proliferate, protecting the host from further infection. Viruses are usually classified by the Baltimore Classification System, which separates viruses into groups by nucleic acid properties: ...

Current influenza vaccines are trivalent or quadrivalent inactivated split or subunit vaccines administered intramuscularly, or live attenuated influenza vaccines (LAIV) adapted to replicate at temperatures below body temperature and administered intranasally. Both vaccines are considered safe and efficient, but due to differences in specific properties may complement each other to ensure reliable vaccine coverage. By now, licensed LAIV are produced in embryonated chicken eggs. In the near future influenza vaccines for human use will also be available from adherent MDCK or Vero cell cultures, but a scalable suspension process may facilitate production and supply with vaccines. We evaluated the production of cold-adapted human influenza virus strains in the duck suspension cell line AGE1.CR.pIX using a chemically-defined medium. One cold-adapted A (H1N1) and one cold-adapted B virus strain was tested, as well as the reference strain A/PR/8/34 (H1N1). It is shown that a medium exchange is not required for

There are certain groups of people who should not be vaccinated with live attenuated vaccines. Every clinician and scientist knows that. Immunocompromised people (HIV, cancer, organ transplants, others) and pregnant women need to be cautious about live attenuated vaccines such as the chickenpox vaccine at critical times during their condition. If a severely immunocompromised person lives with family, those family members may need to be treated differently too. On the one hand, they should be vaccinated with killed/subunit vaccines to protect their immunocompromised family member. On the other hand, sending the children off on a long holiday the moment they are vaccinated with some live attenuated vaccines may be a fun idea … or they could be exempted - but rather vaccinated to protect their endangered family member. Even this travel/exemption is over-cautious, because most of the live attenuated vaccines do not shed from the vaccinated person, and even then risks are extremely low. It all ...

LPS O-antigen is synthesized with exogenously provided mannose and is attached to the LPS core. Several key proteins are shown being produced with the exogenously provided arabinose (colored dots). Fur (iron uptake regulatory protein) and Crp (cAMP receptor protein) enable bacteria to display wild-type virulence. MurA and Asd are enzymes made in the presence of arabinose that are required for synthesis of the essential peptidoglycan cell wall components muramic acid and diaminopimelic acid, respectively, to maintain the integrity of the cell wall. The LacI repressor protein is also synthesized in the presence of arabinose and acts to repress protective antigen ...

A concise review of poultry vaccination and future implementation of plant-based vaccines. N. SHAHID, A.Q. RAO, P.E. KRISTEN, M.A. ALI, B. TABASSUM, S. UMAR, S. TAHIR, A. LATIF, A. AHAD, A.A. SHAHID and T. HUSNAIN. Every year the growth of the poultry industry is severely threatened by a number of infectious viral, bacterial and parasitic diseases. There are a number of vaccines to control these diseases including inactivated virus vaccines, attenuated virus vaccines, live virus vaccines, and subunit vaccines, but they are often relatively expensive and require cold storage and trained people to administer them, especially in developing countries. Plant-based vaccines provide a better option to control these diseases in low profit margin poultry industry. Still there are some challenges in the field of plant-based, so called green vaccines. Injection-based oral priming is a big challenge for commercialisation of green vaccines so, new techniques are needed in the field of plant-based vaccine ...

is a clinical-stage biotechnology company focused on the discovery, development and commercialization of proprietary Lm-based antigen delivery products. These immunotherapies are based on a platform technology that utilizes live attenuated Listeria monocytogenes (Lm) bioengineered to secrete antigen/adjuvant fusion proteins. These Lm-based strains are believed to be a significant advancement in immunotherapy as they integrate multiple functions into a single immunotherapy and are designed to access and direct antigen presenting cells to stimulate anti-tumor T cell immunity, activate the immune system with the equivalent of multiple adjuvants, and simultaneously reduce tumor protection in the tumor microenvironment to enable T cells to eliminate tumors.. Forward Looking Statements ...
In this study, we demonstrated the immune mechanisms and protection induced by a novel unencapsulated S. pneumoniae attenuated live SPY1 vaccine. An elevated humoral immune response and Th2, Th17, and modulatory cellular responses were detected in immunized mice. Interestingly, we noticed that the upregulation of IFN-γ in immune splenocyte supernatants in C57BL/6 mice was not SPY1 specific but might be triggered by CT, an adjuvant reported to possess the potential ability to stimulate a Th1 immune subset (26), which was different from the response in BALB/c mice (5). The reasons for these differences may be due to the different genetic backgrounds of the BALB/c and C57BL/6 mice (27, 28). In this study, to further investigate the immune mechanisms mediating protection induced by SPY1, several different types of immune deficient mice with different genetic backgrounds (nude BALB/c mice, B cell-deficient BALB/c mice, IFN-γ-deficient C57BL/6 mice, IL-4-deficient C57BL/6 mice, and IL-17A-deficient ...

Q: Why do babies often get fevers after being vaccinated?. A: Part of the natural immune response is the release of molecules called chemokines, which cause fever. As a mama, I know how scary it can be when your little one has a fever, but a post-vaccine fever is indicative of a robust immune response and means they are making great memory B cells. That does not mean you shouldnt treat your babys fever! (Please consult your pediatrician on when you should treat your babys fever.). Q: Whats up with vaccine shedding?. A: Vaccine shedding is something only possible with a live attenuated virus. This is different from the pertussis vaccine, for example, which is an acellular vaccine, meaning it contains various pieces of the pertussis bacterial molecules and is not infectious at all, cannot cause illness ever, and cannot shed. Again, a live attenuated virus is a weakened virus that reproduces so slowly that a normal immune system will take care of it before it causes any harm. If a person is ...

The number of new anal cancer (SCCA) cases in the US has been rising annually; 20% of patients (pts) will develop metastatic (met) disease, which presents an unmet medical need. A large population-based study showed 88% of SCCA were HPV+ and 73% had HPV-16 (Hoots et al IJC 2009). ADXS11-001 (ADXS) is an irreversibly attenuated Listeria monocytogenes immunotherapy that targets HPV-associated cancers. It is bioengineered to secrete an antigen-adjuvant protein fused to the E7 peptide of HPV-16. It allows the generation of tumor antigen specific cytotoxic T cells that infiltrate and destroy tumor cells. This is the 1st P2 trial to assess the efficacy/safety of ADXS in met SCCA. ...

Background: In a 2012 Phase II clinical trial, 300 Bangladeshi children aged 24 to 59 months with no prior influenza vaccine exposure were randomized to receive a single intranasally-administered dose of either trivalent, Russian-backbone, live, attenuated influenza vaccine (LAIV) or placebo. Protocol-defined analyses, presented in the companion manuscript, demonstrate decreased viral detection and immunogenicity for A/H1N1pdm09, relative to the A/H3N2 and B strains. This post hoc analysis of the trial data aims to investigate the LAIV strain differences by testing the hypothesis that preexisting humoral and mucosal immunity may influence viral recovery and immune responses after LAIV receipt. Methods: We used logistic regressions to evaluate the relations between markers of preexisting immunity (ie, hemagglutination inhibition [HAI], microneutralization, and immunoglobulin G and immunoglobulin A (both serum and mucosal antibodies) and LAIV viral recovery in the week post-vaccination. We then ...
Live-attenuated vaccines (LAV) are reputed to be the most cost-effective tools for controlling epidemics. With increasing disease outbreaks caused by virus infections, vaccines will have to be delivered to both adults and children, who may have pre-existing cross-reactive antibodies due to previous exposure with an antigenically related virus strain. We and others have shown in vitro that cross-reactive antibodies can improve vaccine efficacy by enhancing LAV infection in Fc gamma-receptor (FcgR) expressing antigen-presenting cells (APCs), a process known as antibody-dependent enhancement (ADE). However, the relevance and occurrence of ADE has yet to be demonstrated clinically. We conducted an open-label trial where subjects are sequentially immunized with the inactivated Japanese Encephalitis (JE) vaccine (Ixiaro®) followed by a live-attenuated yellow fever (YF) vaccine (Stamaril®). To generate a range of cross-reactive antibodies concentrations, subjects were divided into 3 groups, where ...
You and hubby could have interesting discussions. Live virus vaccines are avoided if possible. The inhaled flu vaccine is a live virus used only with children with a strong immune ststems. They may result in developing a mild case of the flu. This asthmatic cannot use it because of my compromised immune system. The first set of vaccines are not wasted on old people like me who probably had or were exposed to those diseases as children so probably have some natural immunity ((obviously the best). For whatever reason Europeans use more live virus vaccines and different suspension agents. You should attend the American Microbiology conference at the end of this month. Lol. Try some Microbiology sites such as ASM; CLMA; CDC. Web MD is a site he respects. As Microbiologists attempt to develop new vaccines they like using blood samples from those who naturally survived the disease to determine what was unique to that individual. While working to develop a vaccine for H1N1, corpses of those killed by ...

Vaccines train the adaptive immune system to identify previously unknown pathogens and induce highly targeted and long-lasting memories. This can be achieved by either infecting humans with a weakened or inactivated strain that induces an immune response while reducing pathogenic responses to a minimum, or by presenting virus-derived particles to the adaptive immune system thereby simulating an actual infection. Live attenuated vaccines are available since the 1950s and induce excellent immunological responses leading to long-lasting immunity against targeted pathogens. However, since individuals are infected with an active virus, this strategy has several risks. Weakened strains have the potential to revert back to a more pathogenic form and cause diseases. This is a particular concern for patients with weakened immune systems and life vaccines are generally not given during pregnancy due to safety concerns. Additionally, designing virus strains that are unable to cause pathogenic responses but ...
SV40 hybrid viruses. Dr. Lewis also worried that foreign cellular DNA common in childhood vaccines could include viral oncogenes capable of causing cancer. · The scientists presented a question to themselves as to whether or not an attenuated vaccine strain could revert into a variant virus capable of replicating so fast that it would cause AIDS. They agreed that they were unable to answer this question. · On the question whether or not mutation events could occur in children after vaccination, the answer was that Recombination among a variety of viruses [contaminant viruses] and cells co-infected in tissue culture is not uncommon. What this basically means is that because it is not uncommon for genetic codes of both contaminant viruses and living cells to recombine and create mutations in laboratory cultures, it can certainly occur in a childs body after vaccination. · Dr. Hana Golding, Chief of CBERs Laboratory of Retrovirus Research, raised the fear that although DNA fragment ...
