Abstract:
Objective To evaluate immunogenicity of one dose or two dose salk strain inactivated poliovirus vaccine(Salk -IPV )among children under seven years .Methods Searching "National Center for Biotechnology Information ,NCBI ","Cochrane Library ""China Biology Medicine disc ,CBMd ","China National Knowledge Infrastructure ,CNKI ","Wanfang Database,WF",studies for assessing immunogenicity of Salk -IPV were included.The seroconversion rate (SR)of neutralization antibody (NA)of specific type of polio virus with an interval of one month after vaccination was used as our endpoints.Pooled SR with 95% Confidence Interval (CI)was calculated by RevMan5.1 software.The association between seroconversion and age at administration was described by R 3.2.2 program.Results A total of 1 1 studies were included.One dose of Salk -IPV seroconvert 29% (95%CI:1 9% -39%),41 %(95%CI:31 % -51 %)and 38% (95%CI:28% -48%)of infants aged 7 years against serotypes I,Ⅱ,and Ⅲ on average,while 2 doses seroconvert 82% (95% CI:74% -90%),83% (95% CI:77% -88%) and 91 % (95% CI:87% -95%),respectively. Seroconversion increased with the starting age for both one dose and two dose schedules.Conclusion Routine immunization with at least 2 doses of Salk -IPV was recommended as a sequential schedule with two -valent oral polio virus vaccine and Salk -IPV was applied.
