  1. Fulltext. Vaccine use and the risk of outbreaks in a sample of nursing homes during an influenza epidemic.

    Article - En anglais


    This study was conducted in nursing homes in a seven-county area of lower Michigan.

    Seventy percent of the 83 nursing homes in the study area provided data on vaccine use.

    Singificantly higher rates of vaccination were found in smaller vs larger nursing homes ; a requirement of written informed consent lowered the frequency of vaccination among residents.

    Among a subset of 45 homes that collected weekly prospective illmess data during the confirmed epidemic of influenza A (H3N2), 17 (38%) experienced an influenza outbreak.

    In bivariate analyses, both greater size of nursing home and lower frequency of vaccination were significant predictors of outbreak status, suggesting a role for indirect protection or herd immunity.
