When a person is given Supemtek, the body’s natural defence (the immune system) produces protection against the influenza virus. None of the ingredients in the vaccine can cause flu.

As with all vaccines, Supemtek may not fully protect all persons who are vaccinated.

Flu can spread very fast.

• It is caused by different types of flu virus that can change every year. This is why you might need to be vaccinated every year.
• The greatest risk of catching flu is during the cold months between October and March.
• If you were not vaccinated in the autumn, it is still sensible to be vaccinated up until the spring since you run the risk of catching flu until then.

Your doctor will be able to recommend the best time to be vaccinated.

Talk to your doctor, pharmacist or nurse before receiving Supemtek.

As with all vaccines, Supemtek may not fully protect all persons who are vaccinated.

• you have a short-term illness with fever. Vaccination may need to be delayed until your fever has gone.
• you have a weakened immune system (immunodeficiency or you are taking medicines that affect the immune system such as cancer medicine (chemotherapy) or corticosteroid medicines).
• you have a bleeding problem or bruise easily.
• you have fainted with an injection before. Fainting can happen after, or even before an injection.

If any of the above apply to you (or you are not sure) talk to your doctor, pharmacist or nurse before receiving Supemtek.

Tell your doctor or nurse if you are using, have recently used or might use any other medicines, including medicines obtained without a prescription or if you have recently received any other vaccine.

Supemtek may be given at the same time as other vaccines by using separate limbs.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this vaccine. Your doctor or pharmacist will help you to decide if you should receive Supemtek.
