Influenza Vaccine

Arch Otolaryngol. 1962;76(6):487-488. doi:10.1001/archotol.1962.00740050501002

The October 6, 1962 issue of the J.A.M.A.1 includes an authoritative summary of the current knowledge of influenza vaccine. The average protection with influenza A, influenza A-Prime and Asian influenza vaccine was 78% in 18 field trials, and against influenza B and influenza B-Prime the average protection was 90% in 4 field trials. With this experience it is urgently recommended that patients in high-risk groups should be inoculated annually. In years of expected high incidence, vaccination of all individuals is advised. It is predicted that a widespread epidemic of Asian influenza will occur in the United States during the 1962-1963 respiratory disease season. This is based on the tendency for Asian influenza to recur with great regularity every two to three years—the last epidemic having been in 1960—and to the fact that Asian influenza has occurred during the past year in sharp outbreaks in Europe and the Far East
