During the 1978-9 season H1N1 influenza was present on the base for 16 weeks, but incidence remained very low in the vaccinated population. The peak incidence of febrile respiratory disease in students was 7.21000week. Cases of influenza occurred almost entirely in persons with H.I. antibody titers for ABrazil78 of less than 8. Military formula vaccine produced a moderately good antibody response in seronegative persons and a marked response in seropositive persons. The first injections of vaccine evoked an excellent response to ATexas77, a satisfactory response to BHong Kong72 and a fair response to ABrazil77. The second injection of vaccine caused insignificant changes in titer for ATexas77 and BHong Kong72, but a substantial increase in titers for ABrazil78, notably in persons whose titers remained low after the first injection. Other respiratory diseases caused little illness during the 1979-80 season. A few cases of adeno virus disease were detected, all in persons who had not received vaccine. Streptococcal infections accounted for about 15 of febrile U.R.I. A few viruses with the characteristics of echoviruses were isolated. Rubella and rubeola were not a problem.
