Abstract

In 1999, the World Health Organization switched from annual to semi-annual recommendations for influenza vaccine composition. We compared the antigenic match between recommendations and circulating viruses before and after 1999, in the Northern and Southern Hemispheres. Vaccine match proportion for A/H3N2 viruses increased from 31% to 59% in the Southern Hemisphere (P<0.05), and is now comparable to that in the Northern Hemisphere. Vaccine match for influenza B decreased from approximately 100% to 33-54% in both hemispheres (P<0.05), following the unexpected resurgence of influenza B/Victoria in 1997. No estimate was available for influenza A/H1N1. We conclude that semi-annual vaccine recommendations are useful overall and discuss potential ways forward, including a recommendation for the improvement of vaccination policy and influenza surveillance in tropical areas.

摘要

1999 年,世界卫生组织将流感疫苗成分的年度建议改为半年建议。我们比较了 1999 年前后南北半球建议与流行病毒之间的抗原匹配情况。南半球 A/H3N2 病毒的疫苗匹配比例从 31%增加到 59%(P<0.05),现在与北半球相当。1997 年乙型流感/Brisbane 病毒意外复活后,两个半球的乙型流感疫苗匹配比例从约 100%降至 33-54%(P<0.05)。对于甲型流感 H1N1,我们没有估计。我们的结论是,半年建议总体上是有用的,并讨论了前进的方向,包括改善疫苗接种政策和热带地区流感监测的建议。
