SECONDARY outcome

Timeframe: 6 months

To assess the number of immune responders and levels of Immunoglobulin G/Immunoglobulin A (IgG/IgA) antibodies to pertussis toxin (PT), filamentous haemagglutinin adhesin (FHA), Pertactin (PRN), and fimbriae 2/3 in serum and nasopharyngeal aspirate. A positive antibody response after vaccination is defined as at least 100% increase from pre- to post-vaccination, to at least 4 times minimum level of detection (MLD) for PT, FHA, PRN, and fimbriae 2/3 in the post-vaccination sample. The 4 antigens described are the standard 4 antigens historically used to describe a serum immunological response to B. pertussis. The absolute serum antibody titers have not shown a correlation of protection in previous pertussis vaccine studies of the current acellular vaccine and there is no known serum antigen threshold of protection for pertussis. Antibodies are measured before vaccination and at 4, 7, 11, 14, 21, 28 days, 6-months and 12-months post-vaccination.
