建議醫生於48小時內採用抗流感葯物, 無論病者曾接受過預防針與否
Seasonal Influenza Vaccine Only 23% Effective This Year
- predominance of influenza A (H3N2) viruses
- overall vaccine effectiveness (VE) was 23%
- This interim VE estimate is relatively low compared with previous seasons when circulating viruses and vaccine viruses were well-matched and likely reflects the fact that more than two-thirds of circulating A (H3N2) viruses are antigenically and genetically different (drifted) from the A (H3N2) vaccine component of 2014–15 Northern Hemisphere seasonal influenza vaccines
-the need for ongoing influenza prevention and treatment measures.
