Efluelda Tetra is a vaccine. This vaccine helps to protect people 60 years of age and older from the flu virus. The use of Efluelda Tetra should be based on official recommendations on flu vaccination.

When a person receives Efluelda Tetra, the immune system (the body's natural defense system) will produce its own protection (antibodies) against the disease. None of the components of the vaccine can cause flu.

The flu is a contagious respiratory disease caused by the flu virus, which can result in mild to severe illnesses, and serious complications such as pneumonia, which can lead to hospitalization or even death. The flu is a disease that can spread quickly and is caused by different types of strains that can change each year. Due to this potential change in circulating strains annually, as well as the duration of protection expected by the vaccine, annual vaccination is recommended. The highest risk of contracting flu is during the cold months between October and March. If you were not vaccinated in the fall, it is still advisable to get vaccinated in the spring, as you are at risk of contracting the flu until then. Your doctor will be able to recommend the best date for you to get vaccinated.

Efluelda Tetra is designed to protect you from the four flu virus strains contained in the vaccine approximately 2 to 3 weeks after injection. Additionally, if you are exposed to the flu immediately before or after vaccination, you may still develop the disease, as the incubation period of the flu is a few days.

The vaccine will not protect you from the common cold, even if some of the symptoms are similar to those of the flu.

To ensure that Efluelda Tetra is suitable for you, it is essential to inform your doctor or pharmacist if any of the following points affect you. If you do not understand anything, consult your doctor or pharmacist to clarify.

Do not use Efluelda Tetra:

• if you are allergic to:

• the active ingredients, or
• any of the other components of this vaccine (listed in section 6), or
• any of the components that may be present in minimal quantities, such as eggs (ovalbumin, chicken proteins) and formaldehyde.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to use Efluelda Tetra.

Consult your doctor before vaccinating if you have:

• a weakened immune response (immunodeficiency or taking medications that affect the immune system),
• bleeding problems or easy bruising,
• experienced Guillain-Barré Syndrome (GBS) (severe muscle weakness) after receiving the flu vaccine,
• if you have a disease with high or moderate fever or an acute disease, vaccination should be postponed until you have recovered.

Your doctor will decide if you should receive the vaccine.

You may experience dizziness after, or even before, any injection with a needle. Therefore, inform your doctor or nurse if you fainted with a previous injection.

Like all vaccines, Efluelda Tetra may not protect all people who are vaccinated.

If for any reason, you undergo blood testing a few days after the flu vaccination, please inform your doctor. This is because false-positive results have been observed in some recently vaccinated patients.
