Name of the Procedure:

Influenza Virus Vaccine, Trivalent (IIV3), Split Virus, 0.5 mL Dosage, for Intramuscular Use

Summary

The trivalent influenza virus vaccine (IIV3) is a flu shot administered intramuscularly to protect individuals against three strains of the influenza virus. This vaccine is given as a 0.5 mL injection, commonly in the upper arm.

Purpose

The influenza vaccine aims to prevent the flu, a contagious respiratory illness causing mild to severe symptoms. It reduces the risk of flu-related complications, hospitalizations, and death, especially in vulnerable populations.

Indications

• Individuals aged 6 months and older.
• Those with chronic health conditions (e.g., asthma, diabetes).
• Pregnant women.
• Healthcare workers and others at high risk of flu exposure.
• Elderly individuals (65 years and older).

Preparation

• No specific fasting required.
• Wear clothing that allows easy access to the upper arm.
• Inform healthcare providers of any medical conditions or allergies.
• Review any current medications, especially blood thinners.
• Diagnostic tests not generally required.

Procedure Description

1. Pre-Injection: The healthcare provider will verify patient information and discuss any concerns.
2. Positioning: The patient is usually seated or standing.
3. Injection Site: The skin of the upper arm (deltoid muscle) is cleaned with an alcohol swab.
4. Administration: Using a sterile needle, 0.5 mL of the IIV3 vaccine is injected into the muscle.
5. Post-Injection: The site is observed for a few minutes to check for any immediate reactions.

Duration

The vaccination process takes approximately 5-10 minutes.

Setting

Typically administered in a healthcare provider’s office, a clinic, a pharmacy, or a community health fair.

Personnel

• Administered by trained healthcare professionals such as nurses or pharmacists.

Risks and Complications

• Common: Soreness, redness, or swelling at the injection site, mild fever, headache, or muscle aches.
• Rare: Severe allergic reactions (anaphylaxis), Guillain-Barré syndrome.

Benefits

• Reduced risk of contracting the flu.
• Decreased severity of symptoms if the flu is contracted.
• Lowered risk of flu-related complications, especially in high-risk groups.
• Benefits generally realized within two weeks of vaccination.

Recovery

• Minimal recovery required.
• Monitor for side effects for a few days.
• Normal activities can usually be resumed immediately.
• Follow up with a healthcare provider if severe reactions occur.

Alternatives

• Quadrivalent Influenza Vaccine (IIV4): Protects against four strains of the flu virus.
• Live Attenuated Influenza Vaccine (LAIV): Nasal spray alternative, not suitable for everyone.
• Antiviral Medications: Can be prescribed if the flu is contracted but do not prevent it.

Patient Experience

• Mild discomfort at the injection site is common.
• Some patients may experience a mild fever or muscle aches.
• Pain management can include over-the-counter pain relievers like acetaminophen or ibuprofen.
• Most side effects are mild and resolve within a few days.
