An MMR Titer is a blood test that checks your antibody titer levels to Measles, Mumps and Rubella. It is run in a laboratory. A titer test is not an injection, shot, or vaccination. An antibody is a component of the immune system.
If you're an adult, get a Td (tetanus and diphtheria) booster shot every 10 years to stay protected. Since some people may lose the protective antibody levels after 5 years, a booster vaccination is recommended if you get a deep, contaminated wound and haven't had a vaccination in more than 5 years.
The other reason that patient got tetanus was that he hadnât had a tetanus shot since he was a young child. In the United States, babies are immunized against tetanus through a series of four vaccinations. Children then receive two tetanus booster shots between the ages of 4 and 12. After age 12, a tetanus booster shot usually is recommended every 10 years. Why are booster shots necessary? Because the immunity provided by a tetanus booster shot begins to wane after five to 10 years.
