    Altmetric:

     

    Bottom Line:

    • The live-attenuated influenza vaccine (LAIV) and trivalent inactivated vaccine (TIV) have been shown to offer benefit(s) during matched seasons, as well as mismatched seasons

    Impact:

    • Our results can help public health officials anticipate the possible infection and complications from influenza during mismatched years
    • Estimates of protection for mismatched influenza seasons can be used by patients who are contemplating immunization
    • Results were used to inform a cost-effectiveness model on vaccination for influenza
