1. What is Engerix-B Junior and what is it used for

Engerix-B Junior is a vaccine that is used to protect against hepatitis B infection. It may also help protect against hepatitis D infection.

This vaccine can be given to newborns, children, and adolescents up to 15 years of age.

Hepatitis B is an infectious disease of the liver caused by a virus. Some people have the hepatitis B virus in their body but cannot get rid of it. These people can continue to infect others and are known as carriers. The disease spreads when the virus enters the body after contact with bodily fluids, almost always blood, from an infected person.

If a mother is a carrier of the virus, she can pass the virus to her child during birth. It is also possible to contract the virus from a carrier through, for example, unprotected sex, sharing injectable syringes, or treatment with medical equipment that has not been properly sterilized.

The main signs of the disease include headache, fever, malaise (nausea), and jaundice (the skin and eyes turn yellow), although in about three out of 10 patients, there are no signs of disease. Of those infected with hepatitis B, one in 10 adults and up to nine in 10 children will become carriers of the virus and are likely to develop severe liver damage and, in some cases, liver cancer.

How Engerix-B Junior works

Engerix-B Junior contains a small amount of the outer surface of the hepatitis B virus. This outer surface is not infectious and cannot cause the disease.

• When you receive the vaccine, it will activate your body's immune system to prepare it to protect itself against these viruses in the future.
• Engerix-B Junior will not protect you if you have already contracted the hepatitis B virus.
• Engerix-B Junior can only help protect you against hepatitis B virus infection.

2. What you need to know before you receive Engerix-B Junior

Do not receive Engerix-B Junior:

• If you are allergic (hypersensitive) to Engerix-B Junior or any of the other components of this vaccine (listed in section 6).
• If you have a fever (high body temperature).

Engerix-B Junior should not be administered if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before receiving Engerix-B Junior. Inform your doctor or pharmacist if you have any allergies or if you have ever had health problems after receiving a vaccine.

Warnings and precautions

Talk to your doctor or pharmacist before receiving Engerix-B Junior if you:

• Are on dialysis for a kidney problem or have a disease that may affect your immune system.

People who need dialysis, have chronic liver problems, are hepatitis C carriers, or are HIV-positive can also receive Engerix-B Junior. This is because hepatitis B infections can be severe in these patients. You will find more information about kidney problems and dialysis in section 3.

If you are not sure if any of the above applies to you, talk to your doctor before receiving Engerix-B Junior.

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

Like other vaccines, Engerix-B Junior may not completely protect you against hepatitis B. A number of factors such as advanced age, sex, overweight, smoking, and some chronic problems reduce the immune response to the vaccine. If any of these apply to you, your doctor may decide to perform a blood test or administer additional doses of Engerix-B Junior to ensure you are protected.

Using Engerix-B Junior with other medicines

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

Engerix-B Junior can be administered at the same time as most routine vaccines. Your doctor will ensure that the vaccines are injected separately and in different parts of the body.

Pregnancy and breastfeeding

• If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, ask your doctor or pharmacist for advice before using this medicine.

Driving and using machines

It is unlikely that Engerix-B Junior will affect your ability to drive or use machines. However, do not drive or use machines if you feel unwell.

Engerix-B Junior contains sodium

This medicine contains less than 23 mg (1 mmol) of sodium per dose, so it is essentially “sodium-free”.

3. How Engerix-B Junior is administered

How your vaccine is administered

Your doctor will administer the recommended dose of Engerix-B Junior.

Engerix-B Junior will be administered:

• as an injection into the muscle of the upper arm in children and adolescents
• as an injection into the thigh in newborns and young children
• as an injection under the skin if you bruise easily or have bleeding problems.

How much is administered

You will receive a series of Engerix-B Junior injections. Once you have completed the injection schedule, you can expect long-term protection against hepatitis B.

• Newborns, children, and adolescents up to 15 years of age will normally receive the 10 micrograms/0.5 ml vaccine.

There are several alternative administration schedules for Engerix-B Junior. Your doctor will choose the most suitable schedule for you.

Schedule 1 – for newborns, children, and adolescents up to 15 years of age

First injection - now

Second injection - 1 month after the first injection

Third injection - 6 months after the first injection

Schedule 2 – for newborns, children, and adolescents up to 15 years of age

First injection - now

Second injection - 1 month after the first injection

Third injection - 2 months after the first injection

Fourth injection - 12 months after the first injection

• In newborns, Schedule 2 allows Engerix-B Junior to be administered at the same time as other routine childhood vaccines.
• This schedule can also be used if you are being vaccinated due to recent exposure to hepatitis B, as it will provide faster protection.

It is very important that you receive your injections at the recommended intervals. If you have any questions about the amount of vaccine you will receive, talk to your doctor.

Vaccination and childbirth

If you have hepatitis B and have just given birth, you can use Schedule 1 or 2 to vaccinate your child.

• Your doctor will also decide whether to administer hepatitis B immunoglobulin (human antibodies) to your child at the time of the first injection. This will help protect your child from hepatitis B. It will be administered in a different injection site.

Kidney problems and dialysis

If your child has a kidney problem or is on dialysis, your doctor may decide to perform a blood test or administer additional doses of the vaccine to ensure your child is protected.
