Why use DT instead of DTaP?

The DT vaccine is used in children who had a bad reaction to a DTaP vaccine, or any other vaccine with a pertussis (whooping cough) component. DT is safer than DTaP for children with these conditions:

  • Progressive neurological illness
  • Uncontrolled epilepsy or seizure disorder
  • Infantile spasms
  • Progressive encephalopathy
  • Unevaluated history of seizures

Pertussis vaccines can sometimes cause severe allergic reactions, seizures, fever over 105°F, brain inflammation (encephalopathy), collapse or shock-like state, Hypotonic-Hyporesponsive Episode (HHE), inconsolable crying for 3 hours or more, and other side effects.

These side effects are almost never associated with DT vaccines, but most children should still get DTaP because the risk of side effects is much lower than the risk of dying in an outbreak of pertussis.

How many shots do I need?
