目的对比部分国家免疫程序,评价预防接种率的研究方法及研究结果的异同,分析研究结果不同的原因。方法利用Endnote7进行文献检索,对相关研究结果对比分析。结果不同研究因研究目的和人群的不同,使用不相同的研究方法,由于不同国家或地区的社会状况、经济和服务模式、提供疫苗服务种类的不同,以及研究人群的不同,研究结果存在类似和不同之处。结论预防接种率研究是根据研究目的而确定的在特定地区、特定人群中开展的调查,部分结果并不能代表整体人群,引用文献需谨慎。 Objective To compare the immunization procedures in some countries, to evaluate the research methods and the similarities and differences of vaccination rates, and to analyze the causes of different results. Methods Endnote7 was used for literature search, comparative analysis of related research results. Results Different studies used different research methods because of different research purposes and populations. Due to differences in the types of vaccines provided by different countries or regions, the types of services provided, and differences in the study population, the findings were similar the difference. Conclusion The vaccination rate study is based on the purpose of the study to determine the survey conducted in a particular area, a specific population, some of the results do not represent the entire population, the citation should be cautious.
