AMBULATORY CARE:

The hepatitis B vaccine

is an injection that helps protect your child from the virus that causes hepatitis B. Hepatitis B is a serious liver infection. The virus is usually spread through contact with the blood or body fluids of an infected person. Your child can also get it by touching an object that has the virus on it. The virus can live on an object for up to 7 days. Your baby can be infected during birth if his or her mother has hepatitis B.

Call your local emergency number (911 in the US) if:

• Your child has signs of a severe allergic reaction, such as trouble breathing, hives, or wheezing.

Seek care immediately if:

• Your child has a high fever or behavior changes that concern you.

Call your child's doctor if:

• You have questions or concerns about the hepatitis B vaccine.

When your child should get the hepatitis B vaccine:

The hepatitis B vaccine is usually given in 3 doses. Your baby may need an additional dose depending on his or her weight and risk for hepatitis B. The vaccine is often given with polio, DTaP, pneumococcal, and Hib vaccines. Your child may need these or other childhood vaccines at certain ages. Contact your child's healthcare provider to schedule a catch-up dose if any routine dose is missed:

• Babies are routinely given a dose of the hepatitis B vaccine within 24 hours of birth. If your baby's mother has hepatitis B, your baby should get the vaccine within 12 hours of birth.
• A second dose is given at 1 to 2 months.
• A third dose is given at 6 to 18 months.

Reasons your child should not get the hepatitis B vaccine or should wait to get it:

Your child should not get the hepatitis B vaccine if he or she has a severe allergy to yeast. Your child should not get a second dose if the first caused a severe allergic reaction. Ask about ingredients in the vaccine that can trigger a reaction if your child has a severe allergy. Wait to get the vaccine if your child is sick or has a fever on the appointment day.

Risks of the hepatitis B vaccine:

The area where your child got the shot may be sore. This should get better in 1 to 2 days. Your child may have a low fever. An allergic reaction to the vaccine may happen after any dose. The reaction can be life-threatening.
