1. What is Boostrix and what is it used for

Boostrix is a vaccine indicated for booster vaccination in children from 4 years of age, adolescents and adults to prevent three diseases: diphtheria, tetanus and pertussis. The vaccine works by helping the body to produce its own protection (antibodies) against these diseases.

• Diphtheria:diphtheria mainly affects the respiratory tract and sometimes the skin. The respiratory tract usually becomes inflamed (swollen) causing severe breathing difficulties and sometimes asphyxia. The bacteria also release a toxin (poison) that can cause nerve damage, heart problems and even death.

• Tetanus (lockjaw):tetanus bacteria enter the body through cuts, scratches or wounds in the skin. Wounds that are particularly prone to infection are burns, fractures, deep wounds or wounds contaminated with dirt, dust, horse manure or wood splinters. The bacteria release a toxin (poison) that can cause muscle stiffness, painful muscle spasms, convulsions and even death. The muscle spasms can be so strong that they cause fractures of the spine.

• Pertussis:pertussis is a highly infectious disease. The disease affects the respiratory tract, causing severe coughing attacks that can interfere with normal breathing. The cough is often accompanied by a "whoop" hence the common name whooping cough. The cough can last 1-2 months or longer. It can also cause ear infections, bronchitis that can last a long time, pneumonia, convulsions, brain damage and even death.

None of the vaccine components can cause diphtheria, tetanus or pertussis.

The use of Boostrix during pregnancy will help protect your baby from pertussis in the first months of life, before they receive their primary immunization.

2. What you need to know before you or your child receive Boostrix

Boostrix must not be administered:

• if you or your child have previously had any allergic reaction to Boostrix or any of the other components of this vaccine (listed in section 6) or to formaldehyde. The signs of an allergic reaction may include skin rash with itching, difficulty breathing and swelling of the face or tongue.
• if you or your child have previously had an allergic reaction to any vaccine against diphtheria, tetanus or pertussis.
• if you or your child have had problems in the nervous system (encephalopathy) in the 7 days following a previous vaccination with a pertussis vaccine.
• if you or your child have had a severe infection with a high temperature (over 38 °C). A minor infection should not be a problem, but consult your doctor first.
• if you or your child have had a temporary reduction in blood platelets (which increases the risk of bleeding or bruising) or brain or nervous system problems after a previous vaccination with a diphtheria and/or tetanus vaccine.

Warnings and precautions

Consult your doctor or pharmacist before you or your child receive Boostrix:

• if you or your child have had any problems after a previous administration of Boostrix or another pertussis vaccine, especially:
• • Fever (over 40 °C) in the 48 hours following vaccination.
  • Collapse or shock-like state in the 48 hours following vaccination.
  • Persistent, inconsolable crying lasting more than 3 hours, occurring within 48 hours of vaccination.
  • Convulsions, with or without fever, occurring within 3 days of vaccination.

• if your child has an undiagnosed or progressive brain disease or uncontrolled epilepsy. The vaccine should be administered once the disease is under control
• if you or your child have bleeding problems or bruise easily
• if you or your child have a tendency to have febrile seizures or if there is a family history of this
• if you or your child have persistent immune system problems due to any cause (including HIV infection). You or your child may still receive Boostrix, but the protection against infections after vaccination may not be as good as in patients with adequate immune responses to infections.

Before or after any injection, fainting (especially in adolescents) may occur, so you should inform your doctor or nurse if you or your child have fainted after receiving an injection in the past.

As with all vaccines, Boostrix may not provide complete protection in all vaccinated patients.

Use of Boostrix with other medicines

Tell your doctor or pharmacist if you or your child are using, have recently used or might use any other medicines or if you have recently received any other vaccine.

Boostrix can be administered at the same time as other vaccines. A different injection site should be used for each type of vaccine. Boostrix may not provide an adequate response if you or your child are taking medicines that reduce the effectiveness of your immune system against infections.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant or plan to become pregnant, consult your doctor or pharmacist before receiving this vaccine.

No data are available on whether Boostrix passes into breast milk. Your doctor will inform you of the possible risks and benefits of administering Boostrix during breastfeeding.

Driving and using machines

It is unlikely that Boostrix will have any effect on the ability to drive or use machines.

Boostrix contains sodium

This medicine contains less than 23 mg of sodium (1 mmol) per dose unit; this is essentially "sodium-free".

3. How to use Boostrix

• Boostrix will be administered as an injection into the muscle.

• The vaccine must never be administered intravenously.

• You or your child will receive a single injection of Boostrix.

• Your doctor will check if you or your child have previously received diphtheria, tetanus and/or pertussis vaccines.

• Boostrix can be used in case of suspected tetanus infection, although other measures to reduce the risk of disease manifestation, such as wound care and/or tetanus antitoxin, should also be taken.

• Your doctor will recommend repeating the vaccination.

4. Possible side effects

After administration of tetanus vaccines, cases of temporary nerve inflammation have been reported very rarely (up to a maximum of 1 in 10,000 doses of vaccine), which can cause pain, weakness and paralysis in the limbs and can sometimes spread to the chest and face (Guillain-Barré syndrome).
