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.
If you've been injured, you may be wondering whether you need to get a tetanus booster shot. You will need a tetanus booster shot if: 1  Your wound was caused by a âcleanâ object, but your last tetanus shot was over 10 years ago.  Your wound was caused by a âdirtyâ object and your last tetanus shot more than 5 years ago.
