Question: 

HOW LONG DOES TETANUS VACCINE TO WORK

Answer: 

Most vaccines require more than one dose over time to produce immunity and long-lasting protection. After an inactivated vaccine like Tetanus and Diphtheria (Td) Vaccine, it takes a couple of weeks for memory cells to develop (memory cells remember how to fight off the infection in the future).

Inactivated vaccines are made from a killed germ that causes the disease. Inactivated vaccines like Td require more than one dose. In general, the first dose “primes” the immune system and the second and/or third dose produces a protective immune response. Immunity from the Td vaccine declines with time and tetanus-containing booster doses are needed to ensure continued tetanus protection at least every 10 years.
