What is the Nasal Spray Influenza Vaccine?

The nasal spray influenza vaccine is a Live Attenuated Influenza Vaccine (LAIV). It is administered by spraying into both nostrils to stimulate the immune system. It must be administered once a year to keep up with the annually changing strains. It can be used as an alternative to the injectable type, effectively preventing and reducing severe complications from the disease. It is a new, convenient, and safe option, especially for children and those uncomfortable with injections.
