The hepatitis B vaccine protects against infection with the hepatitis B virus. A hepatitis B infection can damage the liver and lead to liver cancer.
The hepatitis B vaccine is given as a series of 3 shots. The age at which the first shot is given varies among provinces. Check with your doctor or visit your provincial health website to learn what is recommended in your area.
If your child is exposed to hepatitis B before getting the vaccine, he or she may need a hepatitis B immune globulin (HBIG) shot. This gives instant protection. The HBIG shot will prevent infection until the hepatitis B vaccine takes effect.
The vaccine may cause pain at the injection site. It can also cause a mild fever for a short time. Your child should not get this vaccine if he or she is allergic to baker's yeast. This is the kind of yeast used to make bread. Your child should not get a second or third dose if he or she had a bad reaction to the first shot.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
