First human viral vaccine to prevent cancer (hepatitis B vaccine for liver cancer) was introduced
In 1981, the FDA approved a plasma-derived hepatitis B vaccine for human use. This ﾓinactivatedﾔ type of vaccine involved the collection of blood from hepatitis B virus-infected (HBsAg-positive) donors.
The hepatitis B virus was discovered in 1965 by Dr. Baruch Blumberg who won the Nobel Prize for his discovery.
