An outbreak of influenza A (resembling A/Victoria/3/75) occurred in 2 geriatric wards in February 1976 and, out of 19 patients, 3 died. Of the patients who were at risk, 30% were affected. Immunization for influenza in the elderly just before the winter is suggested. The procedure is simple and inexpensive. The recommendations of the DHSS (U.K.) for the use of influenza vaccine to practising doctors is, therefore, welcome. The suitable treatment appears to be that of repeated immunization with inactivated vaccine. Amantadine in the elderly population may also be effective, and is worthy of trial.
