Diphtheria-Tetanus-Pertussis
A combined vaccine protecting against tetanus, diphtheria, and pertussis (whooping cough). Diphtheria is now mainly seen in international travellers, so a current Tdap booster is especially relevant before a trip.
Dosing & timing
A single Tdap or Td booster, effective within days. Adults should have a booster every 10 years — or after 5 years if you've had a dirty wound or burn. Pregnant travellers should receive Tdap during every pregnancy.
Who should consider it
Travellers to destinations where CDC lists Diphtheria-Tetanus-Pertussisunder “recommended for most” or “recommended for some”. See the country list below for destinations on this site. Your travel doctor will tailor the decision to your itinerary, duration, and health.
Side effects and safety
Most travel vaccine reactions are mild — soreness at the injection site, low-grade fever, headache, or tiredness for a day or two. Serious reactions are rare. Learn more about vaccine safety on CDC.
