1. What is Triaxis and what is it used for

Triaxis (Tdap) is a vaccine. Vaccines are used to protect against infectious diseases. Vaccines make the body produce its own protection against the bacteria that cause these infectious diseases.

This vaccine is used as a booster against diphtheria, tetanus, and pertussis (whooping cough) in children from 4 years of age, adolescents, and adults after completing the primary vaccination schedule.

The use of Triaxis during pregnancy allows the transfer of protection to the child in the womb against whooping cough during the first months of life.

Limitations of the protection provided

Triaxis will only prevent these diseases if they are caused by the bacteria used to produce the vaccine. You or your child may still get similar diseases caused by other bacteria or viruses.

Triaxis does not contain any live bacteria or virus and cannot cause any of the infectious diseases it protects against.

Remember that no vaccine can provide complete and long-lasting protection to all people who are vaccinated.

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

To ensure that Triaxis is suitable for you or your child, it is important that you tell your doctor or nurse if any of the following apply to you or your child. If there is anything you do not understand, ask your doctor or nurse.

Do not use Triaxis if you or your child

• have had an allergic reaction:

• to diphtheria, tetanus, or pertussis (whooping cough) vaccines
• to any other component (listed in section 6)

• to any residual component transferred during manufacturing (formaldehyde, glutaraldehyde) that may be present in small amounts.

• have had a severe reaction that affected the brain within one week of a previous dose of a pertussis vaccine.

• have a severe acute illness. Vaccination should be delayed until you or your child have recovered. A minor illness without fever is not usually a reason to delay vaccination. Your doctor will decide if you or your child should receive Triaxis.

Warnings and precautions

Tell your doctor or nurse before vaccination if you or your child:

• have received a booster dose of a diphtheria and tetanus vaccine in the last 4 weeks. In this case, you or your child should not receive Triaxis and your doctor will decide when you or your child can receive another injection according to official recommendations.
• have had Guillain-Barré syndrome (temporary loss of mobility and sensitivity in the whole body or part of it) within 6 weeks of receiving a previous dose of a vaccine containing tetanus antigen. Your doctor will decide if you or your child should receive Triaxis.
• have a progressive disease that affects the brain/nerves or uncontrolled seizures. Your doctor will start treatment and perform vaccination when the condition has stabilized.
• have a reduced or deficient immune system due to
• • medicines (e.g., steroids, chemotherapy, or radiotherapy).
  • HIV or AIDS infection.
  • any other disease.

It is possible that the vaccine may not protect these individuals in the same way as it protects people with a healthy immune system. If possible, vaccination should be postponed until the end of such illness or treatment.

• have bleeding disorders that cause easy bruising or prolonged bleeding after minor cuts (e.g., due to a bleeding disorder such as hemophilia, thrombocytopenia, or treatment with anticoagulant medicines).

Fainting can occur after any injection with a needle, even before. Tell your doctor or nurse if you or your child have fainted after a previous injection.

Tell your doctor, pharmacist, or nurse before starting to use Triaxis if you or your child have had any allergic reaction to latex. The pre-filled syringes (1.5 ml) with a soft stopper contain a derivative of natural rubber latex (latex) that may cause an allergic reaction.

Other medicines or vaccines and Triaxis

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

Since Triaxis does not contain any live bacteria, it can be administered at the same time as other vaccines or immunoglobulins, although in a different injection site. There are studies that have shown that Triaxis can be used at the same time as some of the following vaccines: hepatitis B vaccine, polio virus vaccine (oral or injectable), inactivated influenza vaccine, and human papillomavirus vaccine, respectively. Injections of more than one vaccine at the same time will be performed in different limbs.

If you or your child are receiving medical treatment that affects the blood or immune system (such as anticoagulants, steroids, or chemotherapy), see the previous section "Warnings and precautions".

Pregnancy, breastfeeding, and fertility

Ask your doctor or nurse if you are pregnant, think you may be pregnant, or plan to become pregnant or are breastfeeding. Your doctor will help you decide if you should receive Triaxis during pregnancy.

Driving and using machines

No studies have been performed on the effects on the ability to drive and use machines. The vaccine has a negligible effect on the ability to drive and use machines.

3. How to use Triaxis

When will you or your child receive the vaccine

Your doctor will decide if Triaxis should be administered to you or your child based on:

• which vaccines you or your child have received in the past.
• how many doses of similar vaccines you or your child have received in the past.
• when you or your child received the last dose of a similar vaccine.

Your doctor will decide what period to wait between vaccinations.

If you are pregnant, your doctor will help you decide if you should receive Triaxis during pregnancy.

Dosage and administration

Who will administer Triaxis to you?

Triaxis should be administered by healthcare professionals trained in the use of vaccines and in a clinic or outpatient setting with the necessary equipment to treat any severe allergic reaction to the vaccine.

Dosage

All age groups for which it is indicated will receive an injection (0.5 ml).

In case you or your child experience an injury that requires preventive action against tetanus, your doctor may decide to give you Triaxis with or without tetanus immunoglobulin.

Triaxis can be used for booster vaccination. Your doctor will recommend repeating the vaccination.

Administration

The doctor or nurse will administer the vaccine in a muscle of the upper outer arm (deltoid muscle).

The doctor or nurse will not administer the vaccine in a blood vessel, buttocks, or under the skin. In case of bleeding disorders, they may decide to inject under the skin, although this may cause more local side effects, including a small lump under the skin.

If you have any doubts about the use of this medicine, ask your doctor, pharmacist, or nurse.

4. Possible side effects

Like all medicines, Triaxis can cause side effects, although not everybody gets them.

When these signs or symptoms occur, they usually develop very quickly after the injection and while you or your child are still in the doctor's office. Severe allergic reactions are a very rare possibility (may affect 1 in 10,000 people) after receiving any vaccine.
