1. What is Avaxim Junior and what is it used for
What is Avaxim Junior
Avaxim Junior is a vaccine. Vaccines are used to protect against infectious diseases.
What Avaxim Junior is used for
This vaccine helps protect against hepatitis A infection.
- It is used in children from 1 year to 15 years of age.
Hepatitis A is an infection caused by a virus that attacks the liver.
- It can be caught through food or drinks that contain the virus.
- Symptoms include yellowing of the skin and eyes (jaundice) and general feeling of being unwell.
How Avaxim Junior works
- When you receive an injection of Avaxim Junior, your body's natural defenses will produce protection against hepatitis A infection.
- This vaccine protects against hepatitis A - but it cannot cause hepatitis A infection.
- This vaccine will not protect against other viruses that attack the liver (such as hepatitis B, hepatitis C, or hepatitis E viruses).
2. What you need to know before you start using Avaxim Junior
Do not use Avaxim Junior if you or your child:
- are allergic to the active substance or any of the other ingredients of Avaxim Junior (listed in section 6).
- are allergic to neomycin. This is an antibiotic used during vaccine production - it may be present in the vaccine in small amounts.
- have had an allergic reaction after a previous dose of Avaxim Junior
- are ill with a high temperature. You should delay vaccination until you or your child recover.
Warnings and precautions
Consult your doctor or nurse before starting to use Avaxim Junior if you or your child have:
- a poor or weakened immune system due to:
- corticosteroids, cancer medicines, radiotherapy, or other treatments that can weaken the immune system. Your doctor or nurse may want to wait until your treatment is finished before vaccination.
- HIV infection (human immunodeficiency virus) or any disease that weakens the immune system. It is recommended to administer the vaccine, although it may not protect in the same way as people with a non-weakened immune system.
- haemophilia or other conditions where bruising or bleeding can occur easily.
- jaundice (yellowing of the skin and eyes) in the past or have lived in an area where hepatitis A is common. You or your child may need to have a test to check if you have had hepatitis A infection before.
- fainted after a previous injection.
Fainting can occur (mainly in adolescents) after any injection with a needle, or even before.
If you are already infected with the hepatitis A virus at the time of using the vaccine, vaccination may not be effective.
As with all vaccines, Avaxim Junior may not fully protect all people who are vaccinated.
Other medicines and Avaxim Junior
Tell your doctor, nurse, or pharmacist if you or your child are taking or have recently taken any other medicines, including medicines obtained without a prescription.
This vaccine can be given to you or your child at the same time as any of the following, but in different parts of the body (e.g. in the other arm or leg) and not mixed in the same syringe:
- vaccines (such as vaccines against diphtheria, tetanus, pertussis, Haemophilus influenzaetype b, poliomyelitis, measles, mumps, and rubella).
- antibodies obtained from blood donors (immunoglobulins) - the vaccine may have less effect if given at the same time as the antibodies. However, you are likely to be protected against hepatitis A infection.
Pregnancy and breastfeeding
If you or your daughter might be pregnant, consult your doctor or nurse before using this vaccine. They will decide whether vaccination should be delayed or not.
You or your child can receive this vaccine during breastfeeding.
Driving and using machines
It is unlikely that this vaccine will have any effect on the ability to drive or use machines.
However, no studies have been developed.
Avaxim Junior contains ethanol, phenylalanine, potassium, and sodium.
- Avaxim Junior contains 2 mg of alcohol (ethanol) in each 0.5 ml dose. The small amount of alcohol in this medicine will have no noticeable effect.
- Avaxim Junior contains 10 micrograms of phenylalanine in each 0.5 ml dose, which is equivalent to 0.17 micrograms/kg for a 60 kg person. Phenylalanine may be harmful to people with phenylketonuria (PKU), a rare genetic disorder in which phenylalanine accumulates because the body cannot eliminate it properly.
- Avaxim Junior contains less than 1 mmol of potassium (39 mg) and sodium (23 mg) per dose, so it is considered essentially "potassium-free" and "sodium-free".
3. How to use Avaxim Junior
The vaccine will be administered by a doctor or nurse, who have been trained in the use of the vaccine and who are used to treating severe allergic reactions that may occur rarely after injection.
When protection begins
Protection against hepatitis A will begin within 2 weeks after the first dose of the vaccine is given.
Long-term protection
If you need long-term protection against hepatitis A, you will need a second dose depending on official recommendations. This dose is called a booster dose.
- The second dose is given preferably between 6 months and 10 years after the first dose of the vaccine.
- Avaxim Junior can be given as a booster dose if you or your child have received a first dose of a different hepatitis A vaccine.
How to administer the vaccine
- The vaccine must be injected into the muscle in the upper outer part of the arm. In young children, it can be injected into the outer part of the thigh.
- If you or your child have a bleeding disorder, the injection can be given under the skin.
- Avaxim Junior will not be administered in the buttocks of you or your child.
4. Possible side effects
Like all medicines, Avaxim Junior can cause side effects, although not everybody gets them.
Severe allergic reactions
Severe allergic reactions (anaphylactic reactions including shock) can always occur, even though this is very rare.
