Influenza Vaccine

The influenza vaccines are aimed at preventing the influenza virus, often referred to as the flu, which is a widespread infection caused by Influenza types A and B. It typically takes a minimum of 2 weeks for the vaccine's protective benefits to develop.

Influenza symptoms can include fever, chills, headache, fatigue, muscle aches, a sore throat, and cough.

Who Should Get the Influenza Vaccine?

As per the National Adult Immunisation Schedule (NAIS) and National Childhood Immunisation Schedule (NCIS), the influenza vaccination, often termed as flu jab or flu shot, is recommended for all individuals, especially those at a higher risk of influenza complications, such as:

• Individuals aged 65 years and older

• Pregnant women in any trimester

• Individuals with chronic medical conditions like diabetes, or heart, lung, liver, and kidney diseases

• Individuals with reduced immunity due to conditions like leukemia, HIV, spleen removal, or organ transplant, or those undergoing treatments such as long-term steroids, certain cancer drugs, or radiation therapy

• Residents of intermediate or long-term care facilities

• Individuals aged 18 years or younger who are receiving long-term aspirin therapy

• Children between 6 months old to 59 months old

Precautions Before Getting the Influenza Vaccine

Before receiving the influenza vaccine, it's crucial to notify your healthcare provider if:

• You have any allergies to this vaccine or any of its ingredients

• You have had Guillain-Barré Syndrome (a rare condition in which the body's immune system attacks the nerves)

• You have a severe allergy to eggs

Influenza Vaccine Administration

The influenza vaccine, also known as the flu shot, is administered either by injection into a muscle or just under the skin. An annual dose is recommended as the influenza viruses constantly evolve, and your body's immunity to these viruses may decrease over time.

Serious Side-Effects of the Influenza Vaccine

Severe allergic reactions (anaphylaxis) are rare and can occur within minutes to a few hours post-vaccination.

Symptoms of a severe allergic reaction can include:

• Swelling of the face, eyes, lips, or tongue

• Difficulty breathing

• Itchy skin rashes over the entire body

If you exhibit any of these symptoms, it's important to contact your healthcare provider straightaway.

Common Side-Effects of the Influenza Vaccine

Some individuals may feel faint after receiving the vaccine. It's recommended to rest for 15 minutes post-vaccination to prevent fainting. Other common side effects can include soreness, redness, or swelling at the injection site, a slight headache, body aches or tiredness, and fever. These side effects typically dissipate on their own within 2 to 3 days. Paracetamol can be taken to help alleviate pain or fever.
