" No vaccine has ever been proven to be effective against any disease. Only the creation of antibodies is tested, which is different than actual immunity to disease.
In fact, recent outbreaks of measles and mumps in those vaccinated provides proof that vaccines are not effective.
The case for hepatitis B vaccines is no different. This vaccine has shown a temporary increase in antibodies, but this does NOT equate to immunity. The vaccine makers themselves do not promise immunity."
