Development of salivary antibodies at the age of 4 or 5 years to group A and C meningococcal polysaccharides (MenA/C PS) was studied among Gambian children, who had received MenA/C conjugate or PS vaccine in infancy. There was also a control group of 64 age matched children. IgG, IgA, and secretory Ig concentrations were measured by enzyme immuno assay. MenA/C PS vaccine induced antibodies both in previously vaccinated and unvaccinated children. The previous vaccination had not induced long lasting IgA-mediated memory. IgA antibodies were secretory, and most of IgG was serum derived. The IgG salivary response seen was similar to the serum response. (C) 2000 Elsevier Science Ltd.
