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.
Do I need a tetanus jab (vaccine) after an accident or injury? You may need a tetanus jab if the injury has broken your skin and your tetanus vaccinations aren't up-to-date. Tetanus is a serious but rare condition that can be fatal if untreated. The bacteria that can cause tetanus can enter your body through a wound or cut in your skin. They are often found in soil and manure.
