How effective is influenza vaccination of healthcare workers on the incidence of laboratory-proven influenza, pneumonia, death from pneumonia and admission to hospital for respiratory illness in those aged 60 years or older resident in long-term care institutions (LTCIs)?
The principal sources of bias in the studies related to attrition and blinding. The studies did not report on adverse events.
Older individuals in LTCIs at risk of influenza may be infected by their healthcare workers. There are no accurate data on rates of laboratory-proven influenza in healthcare workers. Vaccinating healthcare workers against influenza may reduce infections acquired from this source.
