We observed decreased effectiveness of influenza vaccine with increasing time since vaccination for prevention of influenza A(H3N2), influenza A(H1N1)pdm09, and influenza B/Yamagata-associated hospitalizations among adults. Maximum vaccine effectiveness (VE) was observed shortly after vaccination, followed by an absolute decline in VE of about 8%-9% per month postvaccination.
我们观察到,随着接种流感疫苗后时间的延长,流感疫苗预防 A(H3N2)、A(H1N1)pdm09 和 B/Yamagata 型流感相关住院的效果下降。接种后短期内疫苗效果最佳,随后每月疫苗效果绝对下降约 8%-9%。
