Here is an excerpt from Tim O’Shea’s great book.
Please get the facts and make good decisions not only for yourself but for your children too.
Vaccination Is Not Immunization , 3rd ed. 2013
The most reliable vaccine resource for parents about to make the most important decision of the child’s life.
Hepatitis B is an inflammatory liver disease, found most often among drug addicts. Most victims recover on their own within a few months, with no chronic liver disease. In 1991, however, the CDC and the AAP began including Hepatitis B vaccine for all infants. (p 172 ) Why?
Before 1991, hepatitis B vaccine was only given to high risk groups – health workers, drug users, those with multiple sex partners, and those with a history of the disease.
The disease is transmissible from mother to infant, but if the mother tests negative, it is very unlikely that the infant will have multiple sex partners or be an IV drug abuser, know what I’m saying?
Especially within the first day of life. This is the type of common sense notion that gets overlooked when fortunes are to be made.
Efficacy? No long-term studies had been done before the vaccine was forced on the general population. (Neustaedter, p125)  The insert itself says that the vaccine was only monitored for 5 days before it was released on the market! 
Merck had been developing the Hep B vaccine since the early 1970s, and testing it on live populations of monkeys and humans. (p.244)  Formaldehyde, a carcinogenic inactivater used in many vaccines, supposedly tones down the Hep B virus so that the vaccine hopefully doesn’t give the person hepatitis.
But the real horror of Hepatitis B vaccine comes into focus when you find out that this mercury-laden vaccine is given on the first day of life. The EPA safe level of mercury is .1 micrograms per kilogram per day. For an adult, that is.
As of 2004, one hepatitis B shot had 30 times that amount! – FDA Hepatitis Control, 
Side effects? The CDC failed to mention any side effects in 8 million people who received the vaccine before 1991. (p 175)  But a number of studies have documented the following adverse reactions to the Hepatitis B vaccine:
Guillain-Barre enlarged spleen
demyelinating disease anaphylactic shock
autoimmune reactions jaundice 
In a statement to Congress, Director of the Association of American Physicians and Surgeons Jane Orient, MD said that deaths and adverse reactions to hepatitis B vaccines are
“…vastly underreported, as formal long-term studies of vaccine safety have not been completed. 
“…for most children the risk of a serious vaccine reaction may be 100 times greater than the risk of Hepatitis B.”
By 1999, the number of reported severe adverse reactions to the Hep B vaccine became higher than the actual number of cases of the disease itself! ( Townsend Letter, Sep 2000, p 148) 
Hepatitis B vaccination was dropped from the mandatory school program in France in Oct. 1998 after 15,000 citizens filed a class action suit against the government. The reason: hundreds of neurological and auto-immune disorders. (Belkin) 
PARENTS RESPONSIBLE FOR HEP B REACTIONS
There’s a related story every parent should read, especially those who think they’re doing the right thing to vaccinate a newborn with the dangerous Hepatitis B shot. If the baby has a reaction, the parents are now the prime target for accusations of Shaken Baby! Not kidding – this happens all the time. Look at  (Elber)”
“The great enemy of the truth is very often not the lie — deliberate, contrived and dishonest, but the myth, persistent, persuasive, and unrealistic. Belief in myths allows the comfort of opinion without the discomfort of thought.”
