Analysis Of Vaccination Status Of Children Born In A Vaccination Unit From 2000 To 2018 Based On Individual Cases

Objective:To understand the vaccination status of class I vaccines and part of class ii vaccines in the area under the jurisdiction of this unit in Beijing from 2000 to 2018,and discuss the change trend of regional immunity level in recent decades,so as to provide data basis and feasibility guidance for further improving the immunity ability of related infectious diseases in the region in the futureMethods:The retrospective analysis method and field investigation method were used to complete the research.Firstly,relevant data on timely vaccination rate and vaccination rate of primary and partial secondary vaccines were collected from the vaccination information system of our unit from 2000 to 201 8 for analysis,so as to obtain the change trend chart of primary and partial secondary vaccines vaccination rate in the above years,and to evaluate the immune capacity of related diseases.The correlation analysis was carried out between the timely inoculation rate and the inoculation rate of the first class vaccine according to different types to observe whether there was any correlation between the two and the strength of the correlation.Finally,a questionnaire survey was conducted in our unit's vaccination clinic on the willingness of second-class vaccination,and statistical analysis was made on the factors that might affect the willingness of residents in our unit's jurisdiction to vaccinate children with second-class vaccineResults:1.The immunization program vaccines included in this study include BCG vaccine,hepatitis B vaccine,polio vaccine.DPT vaccine,meningitis A vaccine,measles-containing vaccine,JE vaccine,hepatitis A vaccine,meningitis A,C vaccine and White vaccineFrom 2000 to 2008.the pre-immunization planning stage of the immunization program,the overall level was not high.The BCG vaccination rate was generally within 90%,the hepatitis B vaccination rate was between 61%and 100%,and the polio vaccine rate was 55%.100%,the rate of vaccination is between 55%and 100%,the rate of measles vaccine is between 59%and 100%,the rate of JE vaccine is between 56%and 100%,and the rate of hepatitis A vaccine is between 15%and 100%.The Encephalitis A+C vaccination rate is between 8%and 100%.During the expansion of immunization planning in 2009-2018,the BCG vaccination rate remained above 95%,the hepatitis B vaccination rate was between 91%and 97%,the polio vaccination rate was between 74%and 90%,and the Baibai vaccine vaccination rate was 78%?90%,the measles vaccination rate is 91%?96%,the JE vaccination rate is 75%?94%,the hepatitis A vaccination rate is 81%?92%,and the meningococcal A+C vaccination rate is 60%?90%.In the stage of expanding the immunization plan,the only vaccinations that have actually completed the vaccination tasks in our jurisdiction are BCG vaccine,hepatitis B vaccine and measles vaccine.Timely vaccination rate The vaccination rate of immunization planning vaccines ranges from 1%to 94%,which is quite different.According to the research results,in the stage of expanding the immunization program compared to the stage before expanding the immunization program,the vaccination rate of the immunization program in time has increased significantly.The first dose of hepatitis B vaccine is basically increasing year by year,rising from 60%at the beginning of the study,and finally stabilized at 94%.The performance of three doses of timely vaccination is not as good as the first dose,which is stable at about 75%;After the high,the downward trend increased from 50%at the beginning of the study to 92%in 2012,and then gradually decreased to 88%in 201 8.The highest rate of timely vaccination is hepatitis B vaccine,and the lowest rate of timely vaccination is the second vaccination period of meningococcal A and C vaccinesReplacement rate The types of vaccines that have been replaced include hepatitis B vaccine,polio vaccine,baibai vaccine,JE vaccine,and meningococcal A+C vaccine.The overall replacement rate is between 0%and 94%.The current results show that the polio vaccine replacement rate is the highest in our unit jurisdiction,and the ECM A+C vaccine replacement rate is the least.2.This survey also analyzed the correlation between the timely vaccination rate and vaccine-related vaccination rate.The results showed that the correlation between the timely vaccination rate and vaccination rate of BCG vaccine was r=0.978.The correlation between the first-dose timely vaccination rate and the 3-dose vaccination rate of hepatitis b vaccine was r=0.772.There was a correlation between the timely vaccination rate of 3 doses of polio vaccine and the vaccination rate r=0.758.Correlation between DPT vaccine 3-dose timely vaccination rate and vaccination rate r=0.804.The correlation between in-time vaccination rate of 2 doses of meningitis group A vaccine and vaccination rate r=0.860.The correlation between the timely vaccination rate for the first measles vaccine and the vaccination rate r=0.895;The correlation between the timely vaccination rate at 8 months(first)of je vaccine and the vaccination rate r=0.614;The correlation between the timely vaccination rate of je vaccine at 18 months of age(second time)and the vaccination rate r=0.587;The correlation between timely vaccination rate of hepatitis a vaccine and vaccination rate r=0.864;The correlation between the first-in-time vaccination rate and the vaccination rate of meningitis group A and C vaccines r=0.680;There was A correlation between the second timely vaccination rate and the vaccination rate of meningitis group A and C vaccines r=0.-0.283,P=0.428>0.05.There was a correlation between the timely vaccination rate and the vaccination rate r=0.497,P=0.100.Except for the second dose of meningitis A and C group vaccine and the correlation between the timely vaccination rate and the vaccination rate was not statistically significant,the timely vaccination rate and the vaccination rate of other immunization planning vaccines had A high positive correlation.3.There are 6 types of secondary vaccines included in this study,including EV71 vaccine.Hib vaccine,pneumonia vaccine,influenza vaccine,rotavirus vaccine and chicken pox vaccine.The top three vaccination rates are varicella vaccine,Hib vaccine and rotavirus vaccine.The vaccination rate of varicella vaccine in our area is generally around 80%,Hib vaccination rate in recent years is basically at 40%?60%,and rotavirus vaccination rate is basically at 30%?50%.The other three vaccines are all less than 50%.the influenza vaccine is the lowest.and the coverage rate in recent years is only 1 0%.4.Single factor results show that children's age,parity,household registration,monthly household income,family's understanding of vaccination information and the impact of vaccine events are important factors affecting non-immunization planning vaccination within the jurisdiction.Logistic regression analysis shows that families with high monthly income are 12.206 times more willing to receive second-class vaccines than families with low monthly income.Families with better knowledge of vaccination information were 6.552 times more willing to receive second-class vaccination than families without knowledge of vaccination information.Conclusion:1.Evaluation of vaccination coverage rate based on individual immunization program,which reflects the vaccination and record situation objectively.The overall vaccination rate maintained an upward trend.Most vaccination rates were above 90%.The vaccination rate for individual immunization program was below 90%in individual years,and the timely vaccination rate was relatively lower.It is recommended to monitor the vaccination rate based on individual vaccination cases as a necessary means to study the reasons for the low vaccination rate and timely vaccination rate.Improving and consolidating the vaccination rate is still the focus of future immunization programs..2.Over a decade,the overall proportion of non-immunization program vaccination children in a jurisdiction of a vaccination unit is not high,and there has been a downward trend in recent years.As a supplement to the immunization program,non-immunization program vaccination should be actively promoted and recommended,especially the disease burden is relatively high.Important,immunization program vaccines do not cover non-immunization program vaccines that prevent diseases.3.Analysis of the influencing factors of non-immunization program vaccination willingness in the jurisdiction shows that monthly household income and understanding of vaccination information are important factors that lead to the non-optimistic status of non-immunization program vaccination,and targeted improvement suggestions are needed.
