Immunological persistence of a seasonal influenza vaccine in people more than 3 years old.

ABSTRACT: To evaluate antibody persistence of Aleph inactivated split influenza vaccine, 3308 healthy Chinese people more than 3 years old were enrolled in a hemagglutination inhibition (HI) assay before vaccination, 641 were screened by HI assay negative, 437 of which received one dose of Aleph inactivated split influenza vaccine and 204 of which received one dose of control vaccine (recombinant hepatitis B). After vaccination, the receivers were collected blood at 1st month, 3rd month, 6th month and 12th month for Aleh influenza vaccine antibody persistence assess. The antibody test were determined by hemagglutination inhibition (HI) assay. There were significant difference in antibody geometric mean titer between experimental group and control at 1st month and 3rd month after vaccination. Influen
