In order to assess factors associated with reactogenicity of trivalent inactivated influenza vaccine (IIV3) among young children, data on 1538 vaccinees aged 0–5 years in a previous vaccine effectiveness study were analyzed.The most frequent reaction was redness (19%), followed by induration, swelling, itching, and pain (6–12%); there were no serious adverse events. For some local reactions, multivariate...
In 1976, influenza mass vaccination among schoolchildren was started under the Preventive Vaccination Law, which was intended to control epidemics in the community. However, in the late 1980s, questions about this policy and vaccine efficacy arose, and a campaign against vaccination began. In 1994, influenza was excluded from the target diseases list in the Preventive Vaccination Law, without considering...
This study, done during the 2002–2003 season among children <6 years of age to investigate influenza vaccine effectiveness and confounding factors, involved 2913 children (1512 vaccinees, 1401 non-vaccinees) recruited from 54 paediatric clinics. Between December 2002 and April 2003, parents reported their children's maximum body temperatures weekly. Influenza-like illness (ILI) was defined as an...
This study was carried out to investigate the effectiveness of influenza vaccine among 2913 children (1512 vaccinees and 1401 nonvaccinees) under 6 years of age during the 2002–2003 season. Study subjects were recruited from 54 paediatric clinics, located in eight areas in Japan. Maximum body temperatures were obtained weekly from parents between 2002 December 16 and 2003 April 13. Influenza-like...
The efficacy of the influenza vaccine is often underestimated, due to the dilution of the outcome by noninfluenzal illnesses. We thus explored the methodology to evaluate the effect of the inactivated influenza vaccine under the following strict conditions: an assessment of the effectiveness on clinical illness among healthy adults in a small-scale mixed epidemic during the 1991-1992 season. The...
The immunogenicity of the trivalent split-virus influenza vaccine was investigated among 70 healthy adults (mean age: 48.5, range: 36-68). The vaccine antigens were: A/Yamagata/32/89 (H1N1); A/Beijing/352/89 (H3N2); and B/Bangkok/163/90. Regarding the entire sample, the vaccine induced a tenfold or more rise on the average in the hemagglutination inhibition (HAI) antibody to each antigen. The response...
