To under stand influenza A viruses epidemic, antigenicity and genetic characteristics variation between the vaccine and Circulation strains during 2004-2008 year in China.
The influenza A viruses (H1N1, H3N2) isolated from 2004-2008 year were under took antigenic and sequence analysis. Influenza A virus antigenicity and genetic characteristics were analyzed thought amino acid variation compassion of HA1 protein of influenza A virus isolates.
The antigenicity of influenza H1N1 subtype viruses isolated from 2004 to 2007 is very similar with vaccine strain A/New Caledonia/20/1999 (HIN1)-like virus. The influenza H1N1 viruses circulated in 2008 year had similar antigenic characteristics with A/Brisben/59/2007 (H1N1) which is component of influenza vaccines for northern hemisphere 2008-2009 year. The influenza H3N2 subtype viruses of 2004-2005 year had antigenic variation comparatively with vaccine strain A/Fujian/411/12002 (H3N2), The antigenicity of 2006-2007 H3N2 viruses and 2008 year's is A/Wiscansin/67/2006(H3N2) and A/ Brisben/10/2006(H3N2) respectively.
There is change of influenza A viruses (H1N1, H3N2) antigenic and genetic characteristics during 2004-2008 in China.
了解2004 - 2008年中国甲型流感病毒的流行情况、抗原性以及疫苗株与流行株之间的基因特征变异。
对2004 - 2008年分离的甲型流感病毒（H1N1、H3N2）进行抗原性和序列分析。通过对甲型流感病毒分离株HA1蛋白氨基酸变异比较分析甲型流感病毒的抗原性和基因特征。
2004年至2007年分离的甲型H1N1亚型病毒的抗原性与疫苗株A/新喀里多尼亚/20/1999（H1N1）样病毒非常相似。2008年流行的甲型H1N1病毒具有与A/布里斯班/59/2007（H1N1）相似的抗原特征，A/布里斯班/59/2007（H1N1）是2008 - 2009年北半球流感疫苗的一个组分。2004 - 2005年的甲型H3N2亚型病毒与疫苗株A/福建/411/2002（H3N2）相比有抗原性变异。2006 - 2007年H3N2病毒和2008年病毒的抗原性分别为A/威斯康星/67/2006（H3N2）和A/布里斯班/10/2006（H3N2）。
2004 - 2008年中国甲型流感病毒（H1N1、H3N2）的抗原性和基因特征发生了变化。
