live attenuated influenza vaccine

The live attenuated influenza vaccine (LAIV) is a type of flu vaccine made from weakened forms of the live influenza virus. Unlike traditional flu vaccines that use inactivated virus, LAIV is administered as a nasal spray. It stimulates the immune system to recognize and fight the virus without causing illness, providing protection against seasonal flu. The vaccine is suitable for healthy individuals aged 2 to 49, but not for those with certain health conditions. By training the immune system, it helps reduce the risk of contracting the flu and its complications.
