摘要

Killed and live influenza virus vaccines are effective inpreventing and curbing the spread of disease, but newtechnologies such as reverse genetics could be used toimprove them and to shorten the lengthy process of prepar-ing vaccine seed viruses. By taking advantage of thesenew technologies, we could develop live vaccines thatwould be safe, cross-protective against variant strains, andrequire less virus per dose than conventional vaccines.Furthermore, pandemic vaccines against highly virulentstrains such as the H5N1 virus can only be generated byreverse genetics techniques. Other technologic break-throughs should result in effective adjuvants for use withkilled and live vaccines, increasing the number of availabledoses. Finally, universal influenza virus vaccines seem tobe within reach. These new strategies will be successful ifthey are supported by regulatory agencies and if a robustmarket for influenza virus vaccines against interpandemicand pandemic threats is made and sustained
