Abstract

A total of 1, 223 elderly people in nursing homes in Niigata Prefecture, Japan, were immunizedwith one or two doses of commercial trivalent split vaccine formulation, against strains including A/HN, A/H3N2 and B for three seasons (1996-1999). The frequencies of adverse reactions and antibodyinduction were assessed.<BR>Frequent side effects of vaccination were local reactions such as redness and tennerness at thesite of injection, but there were no serious reactions, suggesting that the vaccine was quite safe forthe elderly. Furthermore, antibody induction by immunization was relatively high and independentof the degree of activities of daily living (ADL). Annual repeated influenza vaccination did not diminishprotection against influenza. However, antibody induction against antigens was insufficient in the1997/1998 season, and further improvement in the combination of quantities of the four included antigensmay by required. A booster dose after the first dose did not enhance immune responses in the nursing staff, and the one dose method appeared to be indicated for the elderly.
