BACKGROUND Lowered immune response to hepatitis B vaccines has been found in individuals vaccinated into dorsogluteal site compared to vastus lateralis thigh muscle. OBJECTIVE The aim of this study was to compare the immunogenicity and reactogenicity of a hepatitis B vaccine in infants vaccinated into ventrogluteal or anterolateral thigh sites. DESIGN(More)
Recently, it was suggested that maternal hepatitis B surface antigen antibodies (anti-HBs) acquired transplacentally could play a negative role in newborn infants' immune response to the hepatitis B vaccine. We compared the hepatitis B virus (HBV) vaccine response in infants born to mothers previously vaccinated against HBV (n = 91) to infants born to(More)
Wide serological prevalence of influenza A and B was verified by the serological survey covering 200 students of the University of S. Paulo during the 1984-1985 period. The humoral antibodies were detected by the single radial haemolysis technique, whose arithmetic titres averages were greater for both subtypes, (H1N1) and (H3N2) of the influenza A virus(More)
