title: Epidemiological evaluation of the protection conferred by the Nivgrip vaccine against influenza caused by the A(H3N2) virus.
abstract: The protection conferred by the inactivated influenza vaccine Nivgrip against influenza caused by the A(H3N2) virus was demonstrated in three school communities of a large urban centre during the epidemic outbreaks occurring in the winter season of 1983. The specific protection was reflected by the lower morbidity by influenza-like respiratory infections and by the absence or scarcity of postinfluenza complications in vaccinees.
