Abstract

To improve lower efficacy among infants in low income countries and the safety (e.g., rare but severe intussusception) of live oral rotavirus vaccines, we have developed CDC-9 strain with G1P[8] specificity as a candidate inactivated rotavirus vaccine (IRV). This IRV of 3 doses elicits high titers of IgG, neutralizing activity to homotypic and heterotypic human strains and IgG avidity in guinea pigs, thus is a promising alternative to enhance global immunization against rotavirus in children.

Disclosure of Potential Conflicts of Interest

Drs. Jiang and Glass and Ms. Wang hold patents through CDC for their work with inactivated rotavirus vaccine.
