What is Engerix-B Pediatric?

Hepatitis B is a serious disease caused by a virus. Hepatitis B causes inflammation of the liver, vomiting, and jaundice (yellowing of the skin or eyes). Hepatitis can lead to liver cancer, cirrhosis, or death.

The Engerix-B Pediatric is used to help prevent this disease in children and teenagers.

The vaccine helps your child's body develop immunity to hepatitis B, but will not treat an active infection the child already has.

Vaccination with Engerix-B Pediatric is recommended for all children beginning at birth, especially children and adolescents who are at risk of getting hepatitis B. Risk factors include: living with someone infected with hepatitis B virus; being born to a mother who is infected with hepatitis B; being on dialysis; living in a facility for developmentally disabled people; traveling to areas where hepatitis B is common; being an adolescent who has never received a this medicine during childhood.

Like any vaccine, the Engerix-B Pediatric may not provide protection from disease in every person.

Keep track of any and all side effects your child has after receiving this vaccine. When the child receives a booster dose, you will need to tell the doctor if the previous shot caused any side effects.

Warnings

Tell your child's doctor if he or she uses other medicines or have other medical conditions or allergies.

Before taking this medicine

Engerix-B Pediatric will not protect against infection with hepatitis A, C, and E, or other viruses that affect the liver. It may also not protect against hepatitis B if your child is already infected with the virus, even if he or she does not yet show symptoms.

Your child should not receive this vaccine if he or she ever had a life-threatening allergic reaction to any vaccine containing hepatitis B. Engerix-B Pediatric should not be given to a child who is allergic to yeast.

If your child has any of these other conditions, this vaccine may need to be postponed or not given at all:

• kidney disease (or if the child is on dialysis);

• a bleeding or blood clotting disorder such as hemophilia or easy bruising;

• an allergy to latex rubber; or

• a neurologic disorder or disease affecting the brain (or if this was a reaction to a previous vaccine).

Your child can still receive a vaccine if he or she has a minor cold. If the child has a more severe illness with a fever or any type of infection, your child's doctor may recommend waiting until the child gets better before receiving this vaccine.

Tell your doctor if you are pregnant or breastfeeding.

How is this vaccine given?

The vaccine is injected into a muscle. Your child will receive this injection in a doctor's office or other clinic setting.

The Engerix-B Pediatric is given in a series of shots beginning shortly after birth. The booster shots are sometimes given 1 to 2 months and 6 to 18 months after the first shot. If your child does not receive a birth dose, the vaccine series should begin as early as possible.

Your child's individual booster schedule may be different from these guidelines. Follow the doctor's instructions or the schedule recommended by your local health department.

What happens if I miss a dose?

Contact the doctor if your child misses a booster dose or if he or she gets behind schedule. The next dose should be given as soon as possible. There is no need to start over.

Be sure your child receives all recommended doses of this vaccine. Your child may not be fully protected if he or she does not receive the full series.

What happens if I overdose?

An overdose of this vaccine is unlikely to occur.

What should I avoid before or after receiving this vaccine?

Follow the doctor's instructions about any restrictions on food, beverages, or activity.
