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.
Know if it's time to get your tetanus shot. If you never received the first series of tetanus shots (primary vaccination series) or you're not sure when you had your last tetanus shot, you should go get a tetanus shot. If you've been injured, you may be wondering whether you need to get a tetanus booster shot.
