RESUMEN
In 1985, a new epidemic variant of influenza virus, A/Berlin/6/85 (H3N2) was isolated which differed antigenically from the reference A/Philippines/2/82 virus. The results of the study of population immunity in adults and children of the USSR and GDR to these virus variants confirm the data on the continuing drift of virus A (H3N2).
