AGL2017-82570-RReverse genetics approaches for the development of new vaccines against influenza A virus infections.

Influenza A viruses (IAVs) represent a serious concern globally because they are capable of rapid spread and cause severe disease in humans and other animals. The development and implementation of plasmid-based reverse genetics approaches have allowed the manipulation and recovery of recombinant IAVs from complementary DNA copies of the viral genome. Furthermore, IAV reverse genetics have provided researchers an efficient and powerful platform to introduce specific changes in the viral genome with the final goal of studying IAV biology, designing more effective vaccine strategies, and to reduce the rates of incidence and mortality associated with viral infections. In this review, we briefly discuss IAV reverse genetics and their applications to prevent IAV infections.
