Nasal spray flu vaccine

The flu vaccine can also be administered as a nasal spray instead of the usual injection method. It is an alternative for healthy, non-pregnant people age 5 to 49 who want to be protected from the flu virus. Unlike the regular vaccine, it is a live virus. Therefore, it is best if the person receiving it does not have close contact with people who have a weakened immune system.
