According to a recent study involving over 4,000 children, it appears that mortality rates linked with influenza type A are markedly lower than that of type B. However, influenza type A represents a greater challenge when it comes to immunization due to its ability to mutate and spread quickly. Both the CDC and American Academy of Pediatrics are advising against the live attenuated influenza vaccine (LAIV) vaccination for the 2016-2017 season.
