Long information

What is it and how is it used?

Prepandrix is a vaccine for use in adults from 18 years old. It is intended to be given before or during the next influenza (flu) pandemic to prevent flu caused by the H5N1 type of the virus. Pandemic flu is a type of influenza that occurs at intervals that vary from less than 10 years to many decades. It spreads rapidly around the world. The symptoms of pandemic flu are similar to those of ordinary flu but are usually more severe.

When a person is given the vaccine, the immune system (the body?s natural defence system) will produce its own protection (antibodies) against the disease. None of the ingredients in the vaccine can cause flu.

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

What do you have to consider before using it?

Prepandrix should not be given:

  • if you have previously had a sudden life-threatening allergic reaction to any ingredient of Prepandrix (these are listed at the end of this leaflet) or to any of the substances that may be present in trace amounts as follows: egg and chicken protein, ovalbumin, formaldehyde, gentamicin sulphate (antibiotic) or sodium deoxycholate. Signs of an allergic reaction may include itchy skin rash, shortness of breath and swelling of the face or tongue.
  • if you have a severe infection with a high temperature (over 38°C). If this applies to you then your vaccination will be postponed until you are feeling better. A minor infection such as a cold should not be a problem, but your doctor will advise whether you can still be vaccinated with Prepandrix.

Do not have Prepandrix if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before having this vaccine.

Take special care with Prepandrix:

  • if you have had any allergic reaction other than a sudden life threatening allergic reaction to any ingredient contained in the vaccine, to thiomersal, to egg and chicken protein, ovalbumin formaldehyde, gentamicin sulphate (antibiotic) or to sodium deoxycholate. (see section 6. Further information).
  • if you have problems with your immune system, since your response to the vaccine may then be poor.
  • if you are having a blood test to look for evidence of infection with certain viruses. In the first few weeks after vaccination with Prepandrix the results of these tests may not be correct. Tell the doctor requesting these tests that you have recently received Prepandrix.

Using other medicines or vaccines

Please tell your doctor if you are taking or have recently taken any other medicines, including medicines obtained without a prescription or have recently received any other vaccine.

There are no data on the use of Prepandrix given at the same time as other vaccines. Therefore, Prepandrix is not intended to be given at the same time as other vaccines. However, if this cannot be avoided, the other vaccine will be injected into the other arm. Any side effects that occur may be more severe.

If you take any medicines that reduce immunity to infections or have any other type of treatment (such as radiotherapy) that affects the immune system, Prepandrix can still be given but your response to the vaccine may be poor.

Pregnancy and breast-feeding

There is no information on the use of Prepandrix in pregnant or breast-feeding women. Your doctor needs to assess the benefits and potential risks of giving you the vaccine if you are pregnant or breast-feeding. Please tell your doctor if you are/may be pregnant or intend to become pregnant, or if you are breast-feeding and follow his advice.

Driving and using machines

Some effects mentioned under section 4. ?Possible side effects? may affect the ability to drive or use machines.
