Abstract:
Objective To evaluate the protective efficacy of influenza vaccine in the elderly in China. Methods The Chinese databases (CNKI, Wan Fang, VIP) and English databases (Pubmed, Embase) were searched, then studies related to the protective efficacy of influenza vaccine in the elderly according to pre-designed criteria were included and the vaccine efficacy(VE) was selected as an evaluation index. Rev Man 5.3 and Stata 12.0 were used in this meta analysis. Results A total of 26 studies (2000-2016) including 6 kinds of outcomes were eligible, of which, 22 articles related to influenza like illness (ILI) , 5 articles related to common cold (CC) , 11 articles related to the attendance rate due to ILI and CC, 7 articles about chronic diseases (including Hypertension, Diabetes, Coronary Heart Disease (CHD) , Stroke, Cancer, Chronic bronchitis and others) , 6 articles about chronic disease treatment and 3 articles about all-cause mortality. The VE of influenza vaccine was 58.00% (95%CI: 48.00%-66.00%), 40.00%(95% CI: 30.00%-50.00%), 42.00% (95% CI: 34.00%-49.00%), 17.00% (95% CI: 11.00%-23.00%), 28.00%(95% CI: 14 .00 % -40.00 %) and 28 .00 % (95% CI: 15 .00 % -39 .00 %) , respectively. Conclusion Influenza vaccination can effectively prevent the occurrence of influenza like disease and other symptoms in the elderly in China.
