Whose vaccine helped protect against hepatitis B and was the first designed with recombinant DNA?
Quick Answer
The hepatitis B vaccine was first licensed in 1981 in a recombinant form developed by teams including Maurice Hilleman’s group and genetic-engineering pioneers. It was the first major human vaccine made using recombinant DNA technology.
The Full Story
The hepatitis B vaccine marked a major shift in vaccine design because it used recombinant DNA methods rather than material taken directly from infected human blood. The first recombinant hepatitis B vaccine was licensed in 1981. This approach relied on producing hepatitis B surface antigen in yeast cells, making the vaccine safer and more scalable. It became a milestone in biotechnology as well as preventive medicine.
