INFLUENZA VIRUS VACCINE. THE EFFECT UPON AN OUTBREAK OF THE DISEASE AMONG A GERIATRIC POPULATION.
In an outbreak of laboratory-confirmed influenza A-2 (Asian strain) on a 70-bed geriatric ward in which some patients had received influenza vaccine and some had not, 30 patients out of a total of 75 developed clinical evidence of influenza associated with fever. Of the 30 patients, 24 apparently had not received both doses of the influenza vaccine. Of 29 patients who received two 0.1 ml doses of influenza virus vaccine, six developed clinical evidence of infection, whereas, of the 46 patients who did not receive both doses, 24 developed the illness.
