Why does my child need a hepatitis b vaccine if he is not yet at risk of contracting the disease?

Dangerous disease: Newborns are at risk of hepatits b if the mom is infected and doesn't know it. Some people are silent carriers of this disease. I recommend it at birth even if mom tests negative because it is a safe, effective vaccine against a very bad disease, which causes liver cancer and cirrhosis. It is a series of three shots, and it is required for school attendance.

Life time risk of 5%: Overall lifetime risk of contracting hepatitis b is approaching 5% and higher for some people and in some locations. In addition, shots work far better in younger people and even better in infants, thus the majority of shots being given at this age bracket. Even teenaged patients are ancient when it comes to immunologic response to vaccines and this is the main reason to immunize at a young age.

Safe and effective: Hepatitis b is a serious disease; it can lead to liver cancer and cirrhosis. Expectant mothers are tested for hep b during pregnancy but they may become infected after testing is done. To assure a baby never gets this disease, hep b vaccine is used at birth. The vaccine is safe and it works. In addition, we never think our kids are "at risk" of getting an "adult" disease; until they have it.

It is also less expensive to immunize infants due to the smaller amounts of vaccine used.There is absolutely no reason to not vaccinate

Risk is ever-present: As protective as we parents try to be, certain risks are ever-present. Since we don't have the proverbial crystal ball to determine all risks, prevention is best. Who knows if our children will inadvertently be exposed to infected blood products that can transmit the hep b virus? The vaccine sets up the body's defense before infection occurs.Thankfully the vaccine is proven safe and effective!

Hep B vaccine was...: ...Originally tested in countries where most people were infected at birth, then went on to infect their own children at their birth, and died young of liver cancer. The vaccine worked extremely well and safely. Once we knew this, there seemed to be no reason to wait longer.

He doesn't: While hepatitis is a serious disease, the hepatitis vaccine, in my opinion, is not necessary in children with no risk factors. If mom had prenatal care and is hepatitis negative, and the baby will not be in a high risk environment, I do not see the need to give it right away. It can be done later if necessary. You may want to do more research on your own.

At risk from birth: A child is at risk of catching hepatitis b, from the day he is born. So, the vaccine is usually started on that day. Hepatitis b virus is in blood and bodily fluids, and is very contagious. Almost all people who are carriers of hepatitis b "look normal", so one cannot tell who is carrying the virus, among the general population.

3-dose series, : Hepatitis b vaccination is typically given; 1st dose within 24 hours of birth, 2nd dose at 1-2 months of age, and 3rd dose at 6 mos. Same vaccination can be started at any age with same intervals, i.e., 0, 1, and 6 month.
