[Immunogenecity induced by the VA-MENGOC-BC antimeningococcal vaccine against the ATCC C11. N. meningitidis strain in adolescents 12 years after being vaccinated].

The antibodies' response induced by the VA-MENGOC-BC Cuban antimeningococcal vaccine against the ATCC C11 strain was studied by Bactericidal Serum Trial and ELISA among 184 adolescents from a polytechnic, in Ciego de Avila, that had been immnunized in mass campaings 12 years before. Blood samples were taken before administering the first dose (T0), 4 weeks later (T1), and 4 weeks after the second dose (T2). 12 years after vaccination, 25% of the adolescents presented bactericidal titers > or =1:8 against the evaluated strain.
