Comparison of the protective immunogenicity of hexavalent, J14 and hexavalent-J14 vaccines. ICR mice were immunized i.m. with 30μg of each vaccine at time 0, 3, 6 and 9 weeks. Two weeks after the last immunization, five groups of five mice were challenged i.p. with 2.6 × 103 to 2.6 × 107 CFU of type 6 GAS and the LD50 was calculated.
