Other General Warnings

• You or your child has a poor immune response (immunodeficiency) or is taking medications that may affect the immune system.
• You or your child experiences issues with bleeding or bruising easily.
• You have previously experienced symptoms such as feeling faint, fainting, or other stress-related reactions either before or after any needle injection.
• You or your child has any blood tests scheduled within a few days following the vaccination.
• You or your child has thrombocytopenia or any coagulation disorder.
• You or your child has a high fever or a moderate-to-severe illness on the day. Vaccination is usually postponed until recovery. A mild cold without fever is not a reason to delay.
• You or your child has had Guillain-Barré syndrome within six weeks of a previous influenza vaccine.
• You or your child has had a severe allergic reaction to a previous influenza vaccine, or is allergic to eggs or chicken protein.
• Never inject this vaccine into a vein. A healthcare professional should give it, with facilities available to manage a severe allergic reaction.

• Your doctor or nurse will administer the Fluarix Tetra 2025/2026 vaccine suspension.
• Do not self-inject this vaccine. Please follow any aftercare instructions your doctor or nurse provides.
• It is given as an injection into a muscle, usually the upper arm, or the thigh in infants and young children. It must never be given into a vein.
• Tell the doctor or nurse before the injection about any allergy, any fever on the day, any bleeding problem, and any medicine that affects your immune system.
• Stay where you were vaccinated for a short observation period afterwards so staff can treat any immediate reaction.
• Vaccination is repeated each season. Ask your doctor when your next dose is due, and keep the vaccination record you receive.

• Keep refrigerated at 2°C to 8 °C. Do not freeze. Keep it out of reach of children and pets.
• Do not use the vaccine if it has been frozen.
• Store it in the original carton to protect it from light.
• Do not use the vaccine after its expiry date, or if the packaging is damaged or the contents look unusual. Shake it before use if the leaflet directs.
• Do not dispose of it in household waste or down a drain. The clinic or pharmacy disposes of vaccines and used syringes.

• Fluarix Tetra is a seasonal influenza vaccine. Follow your doctor's advice about vaccination each season.
• Please discuss any allergies or previous vaccine reactions with your healthcare provider before vaccination.
• Fluarix Tetra is generally recommended for individuals aged 6 months and older. Your doctor can confirm if it is right for you.
• Avoid the vaccine if you have a high fever or active flu symptoms; wait until you recover before immunisation.
• Protection takes about two weeks to build, so plan vaccination ahead of the influenza season rather than during an outbreak.
• Influenza activity varies by region and season, so vaccination timing may differ where you live. Your doctor will advise.
• Fluarix Tetra is an inactivated vaccine and cannot give you influenza. Feeling mildly unwell afterwards is the immune system responding.
• It does not protect against the common cold or COVID-19, and it does not prevent every case of influenza, though illness is usually milder.
• If you have a blood test booked in the days after vaccination, tell your doctor you've just been vaccinated, as some antibody tests can read falsely positive.
• Move the vaccinated arm normally and apply a cool compress if the site is sore. Ask your doctor before taking a painkiller, and do not take one beforehand just to prevent side effects.
• Vaccination protects those around you too, including babies too young to be vaccinated and people who cannot mount a strong response.
• Seek help immediately for swelling of the face or throat, difficulty breathing, a widespread rash or fainting.
• Keep your vaccination record and bring it to your next appointment.
