Full Answer

Signs of a severe allergic reaction include hives, difficulty breathing, swelling of the face or throat, dizziness and weakness, states the CDC. Allergic reactions typically begin a few minutes to a few hours after vaccination and require emergency medical attention. Some individuals should not receive a tetanus shot, including those who have a history of severe allergic reaction to the vaccine and individuals who are moderately-to-severely ill. People with a history of seizures, nervous system problems or Guillain Barre Syndrome should speak to a doctor before receiving a tetanus vaccine.

Tetanus shots come in three different varieties: DTaP, Tdap and Td, explains WebMD and the CDC. All three vaccines contain inactivated forms of the disease toxin, causing the body to create antibodies against the diseases. Children under the age of 7 receive DTaP, which protects against diphtheria, pertussis and tetanus. Children and adults between the ages of 11 and 64 receive Tdap, which protects against the same diseases. The Td vaccine protects against tetanus and diphtheria, and health care providers give it as a booster shot every 10 years.
