Hepatitis B Vaccine History
The hepatitis B vaccine is the first
anti-cancer vaccine because it can prevent
liver cancer. Worldwide,
chronic hepatitis B causes 80% of all liver
cancer, which is
the 9th leading cause of death. Therefore, a vaccine that protects
against a hepatitis B infection can also help prevent liver cancer.
History of the
Vaccine
The hepatitis B virus was discovered in 1965
by Dr.
Baruch Blumberg who won the Nobel Prize for
his discovery. Originally, the virus was called
the "Australia Antigen" because it
was named for an Australian aborigine's blood
sample that reacted with an antibody in the serum
of an American hemophilia patient.
Working with Dr. Blumberg, microbiologist Irving
Millman helped to develop a blood test for the
hepatitis B virus. Blood banks began using the
test in 1971 to screen blood donations and the
risk of hepatitis B infections from a blood transfusion
decreased by 25 percent. Four years after discovering
the hepatitis B virus, Drs. Blumberg and Millman
developed the first hepatitis B vaccine, which
was initially a heat-treated form of the virus.
First Commercial
Hepatitis B Vaccine
In 1981, the FDA approved a more sophisticated
plasma-derived hepatitis B vaccine for human
use. This “inactivated” type of vaccine involved the collection of blood from hepatitis B virus-infected(HBsAg-positive) donors. The pooled blood was subjected to multiple steps to inactive the viral particles that included formaldehyde and heat treatment (or “pasteurization”). Merck Pharmaceuticals manufactured this plasma vaccine as "Heptavax," which was the first commercial hepatitis B virus vaccine.
The use of this vaccine was discontinued in 1990
and it is no longer available in the U.S.
Current Recombinant
Hepatitis B Vaccines
In 1986, research resulted in a second generation
of genetically engineered (or DNA recombinant)
hepatitis B vaccines. These new approved
vaccines are synthetically prepared and do not
contain blood products - it is impossible
to get hepatitis B from the new recombinant vaccines
that are currently approved in the United
States.
