Abstract:
In the course of Sabin-inactivated poliovirus vaccine (S-IPV) development, we have established high-yield virus production techniques based on Vero cell micro-carrier cultures. Development of specific ELISA tests to quantify the antigen content of S-IPV has been achieved. To adjust the immunogenicity of S-IPV so as to be comparable with the conventional-IPV, a new formulation was determined using a potency test using rats. The reformulated S-IPV was shown to be efficacious for the immunization of monkeys.
