• 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 is cleaned before the shot.
  
  
• After vaccination, it is good to wait for 15 minutes to watch for any allergic reactions.
  
  
• You can return to normal activities right after the shot.
  
  
• Try to get vaccinated before the flu season begins for best protection.
  
  

The vaccine works by training your immune system to recognize the flu viruses.

• It contains inactive parts of four flu viruses (two A strains and two B strains).
  
  
• These parts cannot cause the flu but help your body recognize the real virus.
  
  
• After vaccination, your immune system produces antibodies.
  
  
• These antibodies protect you if you come into contact with the actual flu viruses.
  
  
• It usually takes about two weeks after vaccination for full protection to develop.
  
  

Most side effects are mild and temporary. Common side effects include:

• Pain, swelling, or redness where the shot was given
  
  
• Muscle aches
  
  
• Headache
  
  
• Mild fever
  
  
• Fatigue
  
  
• Nausea
  
  

Rare but serious side effects include:

• Allergic reactions such as 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 had a serious allergic reaction to a previous flu vaccine or ingredients.
  
  
• People with severe egg allergies should consult their doctor before vaccination.
  
  
• If you are moderately or severely ill, wait until you recover before getting the vaccine.
  
  
• Inform your healthcare provider if you have bleeding problems or take blood thinners.
  
  
• Talk to your doctor if you are pregnant, breastfeeding, or have a weak immune system.
  
  

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

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

• Other vaccines: It can be given at the same time as other vaccines but in different parts of the body.
  
  
• 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, such as steroids or chemotherapy drugs, might reduce how well the vaccine works.
  
  
• Allergy concerns: Tell your doctor if you have allergies to eggs, previous flu vaccines, or vaccine ingredients.
  
  
• Current illness: If you have a fever or infection, wait until you recover before getting vaccinated.
  
  

Always inform your healthcare provider about all medicines and supplements you take.

• 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.
