Purpose
The flu vaccine is designed to protect individuals from getting the flu, a contagious respiratory illness that can cause mild to severe symptoms, and complications such as pneumonia or worsening of chronic conditions. The goal is to reduce the severity of the illness and prevent flu-related hospitalizations and deaths.

Preparation
- No special preparation is needed for receiving the flu vaccine.
- Patients should inform their healthcare provider about any allergies or adverse reactions to previous vaccinations.
- It is recommended to stay hydrated before the appointment.
Procedure Description
- Pre-procedure: The healthcare provider will assess the patient’s health status and confirm there are no contraindications.
- Injection: The provider will clean the injection site (usually the upper arm) with an antiseptic and use a sterile needle to inject the vaccine intramuscularly.
- Post-procedure: The patient may be asked to stay for a short period (about 15 minutes) to monitor for any immediate adverse reactions.
Duration
The entire process, including monitoring, typically takes less than 30 minutes.
