Immunization roulette: influenza occurrence in five nursing homes.
Immunization with A/Bangkok 1/79 (H3N2) vaccine appeared to be protective for immunized nursing home residents during an influenza outbreak in 1983. All thirteen deaths during the 4-month period of the study were among residents of two of five nursing homes where influenza immunization was low or nonexistent. Death certificates included a diagnosis of I-ILI for only six of the 13 decedents, showing that I-ILI may be greatly underreported as a cause of death, and skewing statistical evaluation of the impact of influenza in nursing home populations. The cost of protection is only a small fraction of the cost to society of caring for seriously ill nursing home residents with I-ILI who must be admitted to a hospital.
