Problems solved by technology

However, the isolated avian influenza virus has 15 H antigens and 9 N antigens. The different combinations of the two antigens can form hundreds of serotypes, and the popular virus subtypes are unstable, resulting in "drift". It has brought great difficulties to the development of vaccines and the diagnosis and control of bird flu
