摘要: The safety and immunogenicity of a group A plus C meningococcal polysaccharide-CRM 197 conjugate vaccine was evaluated in 304 8- to 10-week-old Gambian infants. Infants were immunized with one, two, or three doses two polysaccharide vaccine. produced few systemic side effects, local reactions similar those by the Postvaccination antibody levels, measured ELISA, increased progressively after However, one dose ofconjugate given at age 6 months induced higher response than did 2 months. Two levels Thus, this new proved be safe immunogenic
