What types of flu shots or influenza vaccines are available?
There are two types of flu shots or influenza vaccines available for children and adults. The first kind is the traditional flu shot. The flu shot does not contain a live virus and cannot cause the flu. This influenza vaccine is an inactivated virus that is given with a needle. The other kind is a nasal influenza vaccine called FluMist. This influenza vaccine contains weakened viruses, which usually do not cause illness but sometimes can cause runny nose, congestion, and fatigue. The nasal influenza vaccine is recommended only for non pregnant, healthy people, ages 2 years to 49 years. For in-depth information on flu prevention, see WebMD’s What is FluMist?
