The disease killed over 80 million people in the world before the vaccine was introduced. After the vaccine, there was only 30 cases discovered in the United States in 2016. Cases have declined over 95% and deaths have declined over 99% since 1937.
The tetanus vaccine was introduced in 1937. The vaccine is used to help prevent the disease "Tetanus" which causes "lockjaw", a painful contraction of all of your muscles.
There are 4 different types of tetanus vaccines, depending solely on age. DTaP and DT are given to children under 7 years old. Tdap and Td are given to children over 7 years old and adults.
Tetanus is not a live virus. The function of the t and b cells are seen in the diagram below.
