Nasal spray flu vaccine

The flu vaccine can also be administered as a nasal spray instead of the usual injection method. It can be an alternative for healthy people age 2 to 49 who want to be protected from the flu virus. Pregnant women should get a flu shot, not the nasal spray flu vaccine. 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.
