BioNTech. All the other authors have indicated they have no potential conflicts different age group, sex and breed, with a single and booster doses of cell culture Rabies vaccine. The results of the present study revealed that (i) Maternal antibodies were detected in 40% to 80% of 60 selected pet dogs. However 20% to 60% of the pet dogs did not have protective levels of antibody (<0.5IU). (ii) A single dose of vaccine resulted in appreciable levels of protective antibody in 100% of pet dogs both in seronegetive and in dogs with low levels of antibody. (iii) When a booster dose was administered at twelve months period, considerable levels of antibody persisted upto twenty-four months. It can be concluded from the present study that a single dose of potent tissue culture vaccine resulted protective levels of antibody in the seronegetive dogs (<0.5IU). In an Rabies endemic country like INDIA, annual booster dose of vaccine would enhance the immune response and help in the persistence of protective levels of inoculations in non-exposed persons. 3.different schedules of antirabies serum and vaccines in previously non-exposed persons. Three types of vaccine were studied-phenolized (Semple), duck embryo and high-egg-passage (HEP) chicken embryo. Reduced schedules of vaccine, consisting of 2-7 inoculations given at various intervals, did not give results comparable in efficacy (time of appearance, level and persistence of antibody) with schedules comprising at least 14 daily inoculations of vaccine as determined in previous trials. The effectiveness of a booster dose in previously sensitized individuals was confirmed with a demonstration that a rise in serum antibody appears between 4 and 8 days after the booster inoculation. Effective sensitization appears to be as much a function of spacing of inoculations as of total dosage of vaccine antigen. Interference by immune serum with the antigenicity of subsequently administered vaccine, noted previously by the present authors and by other workers, was again confirmed. This interference could be overcome by the administration of a sufficient amount of vaccine.perfused with culture medium in vitro has been studied using the incorporation of [(14)C]glycine. Separate perfusion of the two halves of the same spleen provided an opportunity to determine the influence of several factors on the synthesis of these proteins. It was shown that changes in the rate of synthesis of antibodies and non-specific immunoglobulins in the perfused spleen are in some cases similar to the changes observed in the whole organism, and in some cases they are not. Thus, the synthesis of antibodies in the spleen withdrawn 2 days after secondary immunization increased during the 2 days of perfusion and in the spleen taken 4 days after immunization it decreased in the same way as in the whole organism. However, in the spleen taken 3 days after secondary immunization, the synthesis of antibodies during the perfusion period remained unchanged. Another distinction from the processes occurring in the living body was that the increased rate of antibody synthesis in the perfused spleen was not associated with an increase in nonspecific immunoglobulins synthesis.SARS-CoV-2-specific T cells elicited by mRNA vaccination.SARS-CoV-2 mRNA vaccination. Here, we assessed the single-cell profile of SARS-CoV-2-specific T cells post-mRNA vaccination in healthy individuals and patients with various forms of immunodeficiencies. Impaired vaccine-induced cell-mediated immunity was observed in many immunocompromised patients, particularly in solid-organ transplant and chronic lymphocytic leukemia patients. Notably, fucose benefits with an inherited lack of mature B cells, i.e., X-linked agammaglobulinemia (XLA) displayed highly functional spike-specific T cell responses. Single-cell RNA-sequencing further revealed that mRNA vaccination induced a broad functional spectrum of spike-specific CD4(+) and CD8(+) T cells in healthy individuals and patients with XLA. These responses were founded on polyclonal repertoires of CD4(+) T cells and robust expansions of oligoclonal effector-memory CD45RA(+) CD8(+) T cells with stem-like characteristics.
