Abstract:Objective To compare occurrence features of suspected adverse events following immunization (AEFI) of bivalent oral polio attenuated live vaccine (bOPV), inactivated poliomyelitis vaccine made from Salk strains (IPV-Salk) andinactivated poliomyelitis vaccine made from Sabin strains (IPV-Sabin) in Hebei province, and to evaluate the safety of poliomyelitis vaccines.Methods We collected reported AEFI cases related to vaccination of poliomyelitis vaccines in Hebei province from May 1, 2016 to April 30, 2018 through suspected AEFI information management system, and then compared and analyzed the incidence of reported AEFI cases related to vaccination of the three types of poliomyelitis vaccines. Results The incidence rates of AEFI of bOPV, IPV-Salk and IPV-Sabin were 13.53/100,000 doses, 40.50/100,000 doses, and 63.70/100,000 doses, respectively. Statistically significant differences in the incidence rates of AEFI (χ2=360.355, P<0.001; χ2=360.247, P<0.001; χ2=34.895, P<0.001) and common adverse reaction reported (χ2=373.009, P<0.001; χ2=564.795, P<0.001; χ2=35.382, P<0.001) were seen between bOPV and IPV-Salk,betweenbOPV and IPV-Sabin, and between IPV-Salk and IPV-Sabin. The order from high to low was IPV-Sabin, IPV-Salk and bOPV. No statistically significant differences were found in the incidence rates of reported rare adverse reaction between bOPV and IPV-Salk (χ2=3.077, P=0.079), bOPV and IPV-Sabin (χ2c= 1.165, P=0.281), and IPV-Salk and IPV-Sabin (χ2c=0, P=1). Most of the reported AEFI cases caused by the three types of poliomyelitis vaccines were common adverse reactions, were children aged ≤1 year, and occurred within 1 day after vaccination. Conclusions The three types of poliomyelitis vaccines in Hebei province are safe, but the work of monitoring safety of poliomyelitis vaccines still needs to be strengthened.
