• Fluarix PF Quadrivalent is given by a healthcare professional as an injection.
  
  
• The usual injection site is the upper arm muscle for adults and older children, or the thigh muscle for young children.
  
  
• The injection site should be cleaned with an antiseptic before the shot.

• You can return to your normal activities right after vaccination.
  
  

Try to get vaccinated before the flu season begins to get the best protection.

Fluarix PF Quadrivalent helps your immune system recognize and fight the flu virus:

• It contains small, inactive parts of four flu viruses (two A strains and two B strains).
  
  
• These pieces cannot cause flu but teach your immune system to recognize and attack the real virus.
  
  
• After vaccination, your body makes antibodies that protect you if you meet the actual flu viruses.
  
  

It usually takes about two weeks for your body to build full protection.

Most side effects are mild and temporary, including:

• Pain, redness, or swelling at the injection site
  
  
• Muscle aches
  
  
• Headache
  
  
• Mild fever
  
  
• Fatigue
  
  
• Nausea
  
  

Rare but serious side effects can occur, such as:

• Allergic reactions like rash, itching, swelling, or difficulty breathing
  
  
• High fever
  
  
• Severe muscle pain or weakness
  
  

If you notice any serious symptoms, seek medical help immediately.

• Do not get this vaccine if you have had a serious allergic reaction to a previous flu vaccine or any ingredients in Fluarix PF Quadrivalent.
  
  
• People with severe egg allergies should talk to their doctor before vaccination.
  
  
• If you are moderately or severely ill, wait until you recover before getting vaccinated.
  
  
• Inform your healthcare provider if you have bleeding disorders or take blood thinners.
  
  
• Discuss with your doctor if you are pregnant, breastfeeding, or have a weakened immune system.
  
  

This vaccine is safe for children aged 6 months and older.

Fluarix PF Quadrivalent can interact with other medicines or vaccines. Important points include:

• Other vaccines: It can be given at the same time as other vaccines, but injections should be given at different body sites.
  
  
• Blood thinners: If you take blood-thinning medicines (like warfarin), tell your doctor to avoid excessive bleeding or bruising.
  
  
• Immunosuppressive drugs: Medicines that weaken your immune system (like steroids or chemotherapy drugs) might reduce how well the vaccine works.
  
  
• Allergy concerns: Inform your doctor if you have allergies to eggs, previous flu vaccines, or any vaccine ingredients.
  
  
• Current illness: If you have a fever or infection, wait until you recover before getting vaccinated.
  
  

Always tell your healthcare provider about all medicines and supplements you are taking.

• Children 6 months to 35 months: 0.25 ml per dose, two doses at least 4 weeks apart if it is their first flu vaccination.
  
  
• Children 3 years and older and adults: 0.5 ml once per flu season.
