Except in the case of fever, other adverse events were similar between the 2 groups. An anamnestic response for poliovirus types I, II, and III was elicited by a booster in both groups. The seroconversion rates of the participants who received Sabin-IPV were 100%, 94.9%, and 99.0% (types I, II, and III, respectively), and those of the participants who received Salk-IPV were 94.7%, 91.3%, and 97.9% 1 month after the completion of primary immunization. From the Sabin-IPV and Salk-IPV groups, 570 and 564 infants, respectively, completed the primary immunization and formed the per-protocol population. â€ƒOf 1438 infants, 1200 eligible infants were recruited and received either Sabin-IPV or Salk-IPV. Immunogenicity and safety were assessed on the basis of a protocol. â€ƒIn this double-blinded, parallel-group, noninferiority trial, eligible infants aged 60-90 days were randomly assigned in a ratio of 1:1 to receive either 3 doses of Sabin-IPV or Salk strain-based IPV (Salk-IPV) at 30-day intervals and a booster at the age of 18 months. Â€ƒThe development of a Sabin strain-based inactivated poliovirus vaccine ( Sabin-IPV) is imperative to protecting against vaccine-associated paralytic poliomyelitis in developing countries.

Phase 3 Trial of a Sabin Strain-Based Inactivated Poliovirus Vaccine.

Our results suggest that the differences in epitope structure after formalin inactivation may account, at least in part, for the observed differences in immunogenicity between Sabin and wild-type inactivated poliovaccines. It has been previously reported that type 1 sIPV showed higher immunogenicity to type 1 cIPV whereas types 2 and 3 sIPV induced lower level of immunogenicity than their cIPV counterparts. These alterations were different to those shown by wild-type Saukett strain, used in conventional IPV (cIPV). Sites 1 and 3 were altered on inactivated Sabin 3 virus. Antigenic sites 1-3 were slightly modified during the formalin inactivation of Sabin 2 strain.

The major antigenic site 1 was modified during the formalin inactivation of Sabin 1. The modification of viral antigenic epitopes during the formalin inactivation process was investigated by capture ELISA assays using type-specific and antigenic site-specific monoclonal antibodies (MoAbs).

This paper reviews the development, introduction, characterization, and global status of IPV derived from attenuated Sabin strains. Consequently, trivalent oral poliovirus vaccine was used for polio control in Japan for more than half a century but has now been removed from the list of vaccines licensed for routine immunization. They are the first licensed sIPVs in the world. In Japan, Sabin-derived IPVs (sIPVs) have been developed and introduced for routine immunization in November 2012. In particular, the development of inactivated poliovirus vaccines (IPVs) derived from the attenuated Sabin strains is considered to be a highly favorable option for the production of novel IPV that reduce the risk of facility-acquired transmission of poliovirus to the communities. Development and introduction of inactivated poliovirus vaccines derived from Sabin strains in Japan.ĭuring the endgame of global polio eradication, the universal introduction of inactivated poliovirus vaccines is urgently required to reduce the risk of vaccine-associated paralytic poliomyelitis and polio outbreaks due to wild and vaccine-derived polioviruses.
