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.
Quick Answer. A tetanus shot series is given at 2, 4 and 6 months of age, notes the Centers for Disease Control and Prevention. Boosters are given at 15 to 18 months old, 4 to 6 years old and 11 to 18 years old. A booster every 10 years thereafter is recommended.
