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
Live attenuated influenza vaccine (LAIV) offers the promise of inducing a variety of immune responses thereby conferring protection to circulating field strains. LAIVs are based on cold adapted and temperature sensitive phenotypes of master donor viruses (MDVs) containing the surface glycoprotein genes of seasonal influenza strains. Two types of MDV lineages have been described, the Ann Arbor lineages and the A/Leningrad/17 and B/USSR/60 lineages. Here the safety and immunogenicity of a Madin Darby Canine Kidney - cell culture based, intranasal LAW derived from A/Leningrad/17 and B/USSR, was evaluated in healthy influenza non-naive volunteers 18-50 years of age. In a double-blind, randomized, placebo-controlled design, single escalating doses of 1 x 10(5),1 x 10(6), or 1 x 10(7) tissue culture infectious dose 50% (TCID50) of vaccine containing each of the three influenza virus re-assortants recommended by the World Health Organization for the 2008-2009 season were administered intranasally.

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 ...

Figure 1 - Three stages in the delivery of a recombinant attenuated Salmonella vaccine with regulated delayed attenuation, regulated delayed antigen synthesis and regulated delayed lysis in vivo. (In Vitro) The first panel shows a Salmonella bacterium as it is grown in vitro in medium supplemented with the sugars arabinose and mannose. 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 ...

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 ...

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.

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 ...
