Although about 50% both and recipients complained symptoms after dosage, the severity greater recipients. Fourfold hemagglutination-inhibiting antibody titer rises occurred 38% recipients, four vaccines had fourfold nasal antibody. Vaccine virus isolated from three asymptomatic There no virological serological evidence spreading
