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.
Adults need a tetanus vaccine booster every 10 years. You may need a tetanus shot if you've had a dirty traumatic injury requiring a visit to your ER or doctor if it has beeâ¦n more than 5 years since your last Tetanus vaccine.
