Peripheral blood and splenic lymphocytes from rabbits immunized with Pasteurella multocida by various schedules were stimulated to undergo blast transformation in vitro in response to this antigen. Repeated immunizations suppressed this response.

Vaccination is one of the efforts to prevent and overcome Covid-19 pandemic. Currently, vaccination can be given adolescents aged 12-17 years. Vaccines used in national programs are declared safe effective, but there no type vaccine that guaranteed free effects or Post Immunization Adverse Events (AEFI). This study was determine description incidence post-covid-19 immunization adolescents. rese...

We argue that personal belief exemptions to the mandate for childhood immunizations should not be allowed. Parents who choose not to immunize their children put both their own children and other children at risk. Other children are at risk because unimmunized children go to school or day care when they are contagious but asymptomatic, exposing many more children to potentially dangerous infecti...

We have evaluated whether the addition of a foreign helper protein, keyhole limpet hemocyanin (KLH), can augment the efficacy of tumor lysate-pulsed dendritic cells and peptide-pulsed DC immunizations in vivo. Besides being used as a "surrogate antigen" in approaches to measure immunological response in cancer patients, KLH is also an immunogenic carrier protein to elicit T-cell help. Using the...

We evaluated the protective efficacy of 94-kb virulence plasmid-cured, and phoP- or aroA-deficient strains of Salmonella enterica serovar Typhimurium (ΔphoP or ΔaroA S. Typhimurium) as oral vaccine candidates in BALB/c mice. Two weeks after the completion of 3 oral immunizations with 1 × 10(8) colony-forming units (CFU) of virulence plasmid-cured, and ΔphoP or ΔaroA S. Typhimurium at 10-day int...

BACKGROUND The study objective was to determine Washington State childcare facility directors' compliance with state immunization education and monitoring requirements and the role of directors' immunization attitudes and beliefs on compliance. METHODS We mailed a self-administered survey to 2000 randomly selected childcare facility directors in Washington State. The primary outcome measures ...

Immunization of marmosets with platelets from another species of marmoset leads to antibody formation to the donor platelets, deposition of lgG on the host’s platelets, and thrombocytopenia. This disease closely resembles posttransfusion purpura of man, which may develop after one or two transfusions of whole blood. The mode of immunization in the marmoset was found to be important: intravenous...

This study characterized the adverse events following immunization (AEFI) with the novel influenza A (H1N1) 2009 vaccine in Korea. Data on immunization and AEFI were collected between October 27, 2009 and March 15, 2010 through the national immunization registry and passive surveillance systems. The frequency of AEFI and serious adverse events (SAEs) were calculated according to age, sex, p...
