Analysis on sampling survey results of vaccination coverage rates of immunization programme in Renshou County from 2017 to 2022
Objective To comprehensively grasp the vaccination situation of immunization programme in Renshou County,to analyze potential influencing factors,to propose countermeasures for existing problems,and to provide basis for formulating a work plan of immunization programme in the county and improving the work of grassroots immunization programme.Methods According to the sampling survey plan for the vaccination rate of the National Immunization Programme in Sichuan Province,every year from 2017 to 2022,five townships/towns/streets were randomly selected by the"five,six and seven"method.Six villages/communities were randomly selected from each township/town/street.From 2017 to 2019,seven children in the 0-year-old group were randomly selected each year to investigate their basic immunization status,and seven children in each age group from 1 to 6 years old were selected to investigate their enhanced immunization status.A total of 210 children aged 0-6 years were surveyed each year.From 2020 to 2022,seven children aged 0-6 years were surveyed in each village/community,and a total of 1470 children aged 0-6 years were surveyed in each year.Results The sampling survey of vaccination rates from 2017 to 2022 showed that the rate of children's card establishment,the rate of certificate establishment and the matching rate between card and certificate were all 100％.In the basic immunization,the qualified vaccination rates of BCG(bacillus calmette gurin)vaccine,the first dose of hepatitis B vaccine,the whole course of hepatitis B vaccine,polio vaccine,DPT(diphtheria pertussis tetanus)vaccine,vaccines containing hemp,Japanese encephalitis(JE)vaccine,group A meningococcal meningitis vaccine and hepatitis A vaccine were 99.17％,96.81％,94.35％,92.06％,94.13％,94.13％,90.91％,96.59％and 89.60％,respectively.In the enhanced immunization,the qualified vaccination rates of the second dose of vaccines containing hemp,the fourth dose of pertussis vaccine,the second dose of JE vaccine,the first dose of A+C group meningitis vaccine,the fourth dose of polio vaccine,the DPT vaccine and the second dose of A+C group meningitis vaccine were 94.92％,95.12％,96.75％,96.48％,92.42％,96.43％and 95.08％,respectively,with statistical significance.In the analysis of the unqualified rate of basic immunization,the number of people with overdue vaccinations from 2017 to 2022 accounted for 6.98％(87/1 247),19.65％(245/1 247),and 65.28％(814/1 247),respectively.Conclusions The qualified vaccination rates of the immunization programme in Renshou County were not high.Exempt personnel from various prevention and vaccination units should carefully clean up the vaccination objects of all age groups,arrange the vaccination time reasonably,strengthen the notification of vaccination objects,and do a good job in detecting and replanting missed vaccinations among overdue children.The qualified rates of the first dose of BCG and hepatitis B vaccines in newborns were good,and the qualified rates of the enhanced immunization were relatively high.In the future work,publicity and education should be strengthened,and vaccination verification work in spring and autumn should be continuously relied on,to further increase the qualified immunization coverage rate.
