Name of the Procedure:

Influenza Virus Vaccine, Quadrivalent (IIV4), Split Virus, 0.25 mL Dosage, Intramuscular Use

Summary

The Influenza Virus Vaccine, Quadrivalent (IIV4), is an injection given to protect against four strains of the flu. This vaccine is administered into a muscle, typically in the upper arm.

Purpose

The primary goal of the IIV4 vaccination is to prevent influenza infection and its complications. It aims to reduce the risk of flu-related illness, hospitalizations, and deaths.

Indications

• Annual vaccination recommended for individuals six months and older.
• Especially important for those at higher risk of flu complications, such as young children, elderly people, pregnant women, and individuals with certain chronic health conditions.

Preparation

• No special preparation is generally needed.
• Inform your healthcare provider of any allergies or medical conditions.
• You may be asked about any current medications.

Procedure Description

1. Patient Preparation: The patient is seated comfortably.
2. Site Selection: The healthcare professional selects an appropriate injection site, typically the upper arm.
3. Injection: Using a sterilized syringe, 0.25 mL of the vaccine is injected into the muscle.
4. Post-Injection: The site is covered with a small bandage if needed.

Duration

The entire process usually takes about 5-10 minutes.

Setting

• No significant downtime is required, and normal activities can usually be resumed immediately.

Alternatives
