Live attenuated influenza vaccine

Live attenuated influenza vaccine (LAIV) is a type of influenza vaccine in the form of a nasal spray that is recommended for the prevention of influenza. In June 2016, the Centers for Disease Control and Prevention (CDC) stopped recommending the use of LAIV as its effectiveness had appeared to have decreased between 2013 and 2016, but this recommendation was reversed in February 2018, for the 2018-2019 influenza season.
