2013-2014年流感季流感疫苗保護效力評估初探

為評估我國季節性流感疫苗保護效力，提供流感防疫政策參考，疾病管制署自2011年起於每流感季期間，與病毒性感染症合約實驗室合作，選定門診院所為監測點，以病例對照研究法，計算當季流感疫苗保護效力。2013–2014年流感季評估結果顯示，對於不分型之流感，疫苗保護效力為51%；以病毒型別而言，對於主要流行之H3N2流感保護效力為71%，A型流感整體保護力51%，B型流感保護效力34%，本結果顯示接種流感疫苗具保護效益，惟未達統計顯著差異。2014-2015流感流行季仍建議民眾接種流感疫苗以有效預防流感。
Since 2011, Taiwan Centers for Disease Control has been using a sentinel approach to estimate the effectiveness of seasonal influenza vaccine (VE) against laboratory-confirmed medically attended influenza patients. The VE estimate for the 2013–2014 influenza season from a test-negative case-control study was 51% overall, 34% against influenza B, 51% against influenza A, and 71% against H3N2, respectively. Results for the 2013–2014 season indicate that vaccination has reduced the risk for influenza-associated medical visits non-significantly. We continue to recommend that eligible groups shall receive the influenza vaccine for the 2014–2015 season to prevent illness from influenza.
