Trail To Evaluate the Immunity Duration of Different Sequential Immunization Schedules and Effectiveness for Bivalent Oral Poliomyelitis Vaccine Co-administered With IPV Booster Immunization for Poliovirus Vaccine
Trail To Evaluate the Immunity Duration of healthy children who already took part in " The safety and immunogenicity by different sequential schedules of bOPV and bOPV in dragee candy with sIPV, a randomized, double blind, single center and parallel phase Ⅲ clinic trial was performed in Infants of two-month old in Guangxi Province, China" and continue to search for the effects of booster immunization.
Safety and Immunogenicity Evaluation of Different Sequential Immunization Schedules of Type1+2 Bivalent Oral Poliovirus Vaccine(bOPV) Co-administered With Inactived Poliovirus Vaccine(IPV) in Infants Aged 2 Months: a Randomized, Double Blind, Single Center, Parallel Trial
With the progress of the eradication of polio, bivalent oral attenuated live poliomyelitis vaccine against type 1 and 3 (bOPV) and inactivated poliomyelitis vaccine made by Sabin strain (sIPV) are required to use in the "Strategy of Polio Eradication & Endgame Strategic Plan 2013-2018" worldwide. To evaluate the safety and immunogenicity by different sequential schedules of bOPV/tOPV with IPV(sIPV/cIPV), a randomized, double blind, single center and parallel phase Ⅲ clinic trial was performed in Infants of two-month-old in Guangxi Province, China.
