Answer:
Salk Polio Vaccine
The Salk polio vaccine was developed by the American biologist and virologist Jonas Salk and is made from inactivated poliovirus. It was announced to the public on April 12, 1955 and was the first successful vaccine for the prevention of polio. It was made available to the public in the United States in 1955 and is still used today in some countries.
History of the Vaccine
The development of the Salk polio vaccine began with the work of Jonas Salk in 1952. Salk worked on the development of inactivated polio virus vaccines, which are made from killed viruses, and is considered one of the greatest medical breakthroughs of the 20th century. After extensive clinical trials, the vaccine was declared safe and effective in 1955 and began to be administered to the public.
How It Works
The Salk polio vaccine works by introducing a weakened form of the virus into the body, which stimulates the immune system to produce antibodies that will protect against the disease. When a person is exposed to the wild poliovirus, their body will already have the antibodies to fight it off, preventing them from becoming infected.
Benefits of the Vaccine
The Salk polio vaccine has been credited with virtually eliminating polio in the United States and around the world. In addition to protecting individuals from the disease, the vaccine has also helped to reduce the economic burden of treating polio-related illnesses.
