Influenza vaccination, commonly known as the flu shot, involves the injection of a vaccine that provides active immunization against the influenza virus, helping to prevent flu infections.
Purpose
The purpose of this vaccination is to protect individuals from seasonal flu, which can cause severe respiratory illness, complications, and even death, especially in high-risk populations. The goal is to reduce the incidence of flu infections, minimize flu-related complications, and decrease the spread of the virus within communities.

- It may be helpful to wear short sleeves or clothing that provides easy access to the upper arm.
Procedure Description
- A healthcare provider will review your medical history and any potential contraindications.
- The injection site (usually the upper arm) will be cleaned with an antiseptic wipe.
