1. Indications

The influenza virus vaccine, trivalent (IIV3), split virus, preservative-free, for intradermal use is indicated for the prevention of influenza disease caused by the specific strains of the virus included in the vaccine formulation. The vaccine is recommended for individuals who are at risk of influenza complications, including but not limited to:

• High-Risk Populations: Individuals with chronic health conditions, such as asthma, diabetes, or heart disease, who may experience severe illness from influenza.
• Healthcare Workers: Those who are in close contact with patients and are at increased risk of exposure to the influenza virus.
• Older Adults: Individuals aged 65 years and older, who are more susceptible to severe influenza-related complications.
• Pregnant Women: Pregnant individuals, as they are at higher risk for severe illness from influenza and can also pass antibodies to their infants.

2. Procedure

The administration of the influenza virus vaccine involves several key procedural steps to ensure proper delivery and effectiveness of the vaccine. Each step is critical to the overall success of the vaccination process.

• Step 1: Preparation of the Vaccine The vaccine is prepared by ensuring that it is at the appropriate temperature and is well-mixed. This may involve gently shaking the vial to ensure uniform distribution of the vaccine components.
• Step 2: Selection of Injection Site The healthcare provider selects an appropriate site for the intradermal injection, typically the inner forearm, where the skin is thin and easily accessible.
• Step 3: Cleansing the Injection Site The selected injection site is cleansed with an alcohol swab to reduce the risk of infection and ensure a sterile environment for the injection.
• Step 4: Administration of the Vaccine Using a fine needle, the healthcare provider administers the vaccine intradermally, which involves inserting the needle just beneath the skin's surface to deliver the vaccine into the dermal layer.
• Step 5: Post-Administration Care After the injection, the site may be covered with a bandage if necessary, and the patient is monitored for any immediate adverse reactions. Instructions for post-vaccination care and potential side effects are provided to the patient.

3. Post-Procedure

Post-procedure care for the influenza vaccine involves monitoring the patient for any immediate adverse reactions, such as redness, swelling, or pain at the injection site. Patients are typically advised to remain in the healthcare setting for a short period after vaccination to ensure they do not experience any severe allergic reactions. Additionally, patients should be informed about common side effects, which may include mild fever, fatigue, or muscle aches, and are encouraged to report any unusual symptoms. It is also important to remind patients that the vaccine takes about two weeks to provide optimal protection against influenza, and they should continue to practice preventive measures, such as hand hygiene and avoiding close contact with sick individuals, during this period.
