Can I be immunized against tetanus?

Yes,but. Tetanus is seldom given alone today because most folks that need tetanus boosters or the primary series need other protection too. Diphtheria toxoid, tetanus toxoid & acellular pertussis are combined into a single vaccine that is well tolerated & now part of the recommended vaccines for adults.It's use can provide personal benefits & stop the passage of pertussis to infants too young for the vacc.
Yes. People should be vaccinated against tetanus, which is a very serious infection. The dtap for ages 2 months through 6 years, the dt for ages 7-10 years, the tdap and the td for ages 11 years and up, are all vaccines that protect against tetanus.
