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.
Confidence votes 48. A booster tetanus shot should be had every five to ten years. However, if you are 40 or under, you should technically be immune to tetanus because of the new vaccine brought out.ou may need a tetanus shot if you've had a dirty traumatic injury requiring a visit to your ER or doctor if it has bee â¦ n more than 5 years since your last Tetanus vaccine.
