상세 설명
This study is a open-labelled study conducted based on an already finished phase 2 study of the investigational sIPV in 600 healthy infants aged 2-months old. The purpose of this study is to evaluate the cross-neutralization capacity of the serum immuned by the investigational sIPV against 10 individual virus strains. Paired pre-immune and post-immune serum from 250 participants of the phase 2 trial, with 50 in each group including the low-, medium- and high- dosage group, control wild poliovirus vaccine (wIPV) group and control sIPV group, was selected and sent to China Center for Disease Control and Prevention (CDC) for the cross-neutralization assay to determine the neutralizing antibody titer against 10 individual virus strains including Sabin strains (type 1, 2, and 3), Salk strains (Mahoney, MEF-1, and Saukett), cVDPV (type 1, 2, and 3) and Xinjiang wild strain of type 1(Xinjiang wIPV1).
All the subjects in this study had been vaccinated at the schedule of month 0,1, and 2 in the phase 2 clinical trial.
