1. What VAQTA Adult is and what it is used for.

Vaqta Adult is one of a general group of medicines called vaccines. Vaccines are used to protect against infectious diseases. They work by causing the body to produce its own protection against the targeted disease.

This vaccine helps to protect against hepatitis A infection.

Hepatitis A is a virus that attacks the liver, which can be caught from food or drink that contains the virus. Symptoms of hepatitis A include a yellowing of the skin and eyes (jaundice) and feeling generally unwell.

When an injection of this vaccine is given, the body's natural defences will produce protection (antibodies) against the hepatitis A infection. However, it usually takes 2 to 4 weeks after receiving the injection before you will be protected.

This vaccine will not protect you against other viruses that infect the liver (such as hepatitis B, hepatitis C or hepatitis E). This vaccine protects against hepatitis A but cannot cause hepatitis A infection.

The vaccination may not work properly if the person to be vaccinated is already infected with the hepatitis A virus.

Vaqta Adult is for adults aged 18 years and over. This vaccine is not suitable for anyone younger than 18 years of age.

2. What you need to know before VAQTA Adult is given
Do not use Vaqta Adult:
  • if you are allergic to the active substance or any of the other ingredients of Vaqta Adult (listed in section 6) or to neomycin or formaldehyde (see section "Warnings and precautions").
  • if you are ill with a high temperature. The vaccination should be delayed until you have recovered.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before Vaqta Adult is given:

  • if you have ever had an allergic reaction to a previous dose of Vaqta Adult. This vaccine may contain traces of an antibiotic called neomycin and a substance called formaldehyde, both of which are used during vaccine production and may be present in the vaccine in trace amounts.
  • if you have a poor or reduced immune system, due to:
    • corticosteroids, cytotoxic drugs or radiotherapy. Your doctor or nurse may wait until the treatment has finished.
    • HIV (human immunodeficiency virus infection) or any disease that affects the immune system. The vaccine may not protect as well as it protects people whose immune system is healthy.
  • if you have any problems with the blood that causes easy bruising or bleeding for a long time after minor cuts. Your doctor or nurse may still advise that you should have Vaqta Adult but extra care is needed because of the risk of bleeding at the injection site. Your doctor or nurse may give Vaqta Adult as an injection under the skin instead of into muscle (see section 3) to try to reduce the risk of deep bleeding.

The container of this medicinal product contains latex rubber. May cause severe allergic reactions.

As with other vaccines, Vaqta Adult may not completely protect all persons who are vaccinated.

Please tell your doctor if you have a history of jaundice or have lived in an area where hepatitis A is common. Your doctor will determine whether you should be tested for hepatitis A antibodies prior to vaccination.

Other medicines and VAQTA Adult

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines (or other vaccines).

This vaccine can be given at the same time as any of the following provided that they are given in different parts of the body (for example another arm) and are not mixed in the same syringe.

  • Vi polysaccharide typhoid vaccine,
  • Yellow fever vaccine,
  • Immunoglobulins (antibodies obtained from blood donors)

Studies with a paediatric formulation have shown that the vaccine may be given at the same time as measles, mumps, rubella, varicella, pneumococcal 7-valent conjugate, inactivated polio, diphtheria toxoid, tetanus toxoid, acellular pertussis or Haemophilus influenzae type b vaccines.

Pregnancy, breast-feeding and fertility

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 whether you should receive the vaccine.

Driving or using machines

There are no data to suggest that Vaqta Adult affects the ability to drive or operate machinery.

VAQTA Adult contains sodium

This medicine contains less than 1mmol (23mg) per dose, that is to say, essentially ‘sodium-free’.

3. How VAQTA Adult is given

The vaccine will be injected by a doctor or nurse who has been trained in the use of vaccines and who is equipped to deal with any rare severe allergic reaction to the injection.

Short term protection against hepatitis A is achieved within 2 to 4 weeks after receiving this vaccination. This may take a little longer if the injection is given under the skin, rather than into the muscle.

Long-term protection against hepatitis A requires a second dose (booster injection) of an inactivated hepatitis A vaccine. This is usually given between 6 and 18 months after the first dose. This booster will protect you against hepatitis A for at least 6 years. It is predicted that hepatitis A antibodies will remain at least 25 years after vaccination.

If necessary, Vaqta Adult can be given as a booster injection 6 to 12 months after you received a first dose of another inactivated hepatitis A vaccine.

Method of administration

The doctor or nurse will shake the syringe immediately before use and check that the liquid is white and cloudy and that there are no large particles.

The vaccine is given as an injection into a muscle in the upper outer part of the arm. Your doctor or nurse will avoid giving you the injection either into the skin or into a blood vessel. People who are at risk of bleeding a lot after an injection (see section 2) may sometimes be given Vaqta Adult as an injection under the skin but not into muscle to try to reduce the risk of bleeding.

Use in children and adolescents

Vaqta Adult is not recommended for individuals less than 18 years of age.

4. Possible side effects

Like all medicines and vaccines, this vaccine can cause side effects, although not everybody gets them.

As with all vaccines, allergic reactions, in rare cases leading to shock, may occur. These reactions may include:

  • hives
  • difficulty in breathing
  • swelling of the face, tongue and throat
  • dizziness
  • collapse.

When these signs or symptoms occur they usually develop very quickly after the injection is given and while you are still in the clinic or doctor’s surgery. If any of these symptoms occurs after leaving the place where you received the injection, contact a doctor IMMEDIATELY.
