  • Adolescents who have already gotten a booster dose of Td are encouraged to get a dose of Tdap as well. Waiting 5 years after their last Td is encouraged but not required. A period of at least 2 years between Td and Tdap is recommended in these cases.
  • Pregnancy is not a contraindication to Tdap. The only true contraindication to tetanus immunization is a history of neurologic or severe hypersensitivity to a previous dose.
  • Stable neurologic disorders and family history of vaccine reactions are not contraindications to receiving these vaccines.
  • No vaccine has ever been shown to play any role in the development of autism or autism spectrum disorders.
