Tdap vs Td vs DTaP: which tetanus vaccine do you need, and what does each cost?
The three vaccines, side by side
| Vaccine | Ages | Covers | When recommended | Cash price (typical) |
|---|---|---|---|---|
| DTaP Daptacel, Infanrix | 0 to 6 | Diphtheria, Tetanus, Pertussis All full-strength | 5-dose primary childhood series at 2, 4, 6, 15–18 months, and 4–6 years.[2] VFC-eligible kids get it free.[9] | $0 with insurance, ~$25–$40 cash per dose |
| Tdap Boostrix, Adacel | 7 and above | Tetanus (full), diphtheria (reduced), pertussis (reduced) | Single dose for adolescent and adult booster, 11–12 routine and every 10 years thereafter; every pregnancy at 27–36 weeks; after a dirty wound if last dose >5 years.[1][3] | $0 with insurance, ~$50–$95 cash |
| Td Tenivac | 7 and above | Tetanus (full), diphtheria (reduced) | Routine 10-year adult booster when Tdap recently given; sometimes preferred for wound-care boosters in adults already up to date on pertussis.[1] | $0 with insurance, ~$40–$80 cash |
The notation, in plain English
Uppercase letters mean full-strength antigen; lowercase mean reduced. T (uppercase) is full-strength tetanus toxoid in all three vaccines. D vs d distinguishes the pediatric (full) versus adult (reduced) diphtheria dose. P (full DTaP) versus aP (reduced, in Tdap) distinguishes the pediatric versus adult acellular pertussis dose. The reason this matters: a child's immune system needs full priming doses; an adult's already-primed immune system only needs a reduced booster.
Decision tree
DTaP, primary childhood series. VFC-eligible kids get the full series free.[9] Insured kids: typically $0 under ACA preventive. Cash without coverage: ~$25 to $40 per dose, billed at the pediatric provider.
Tdap, every pregnancy, regardless of prior history. The aim is to transfer pertussis antibodies to the newborn before delivery.[3] Covered $0 under ACA preventive maternity care.
Tdap or Td as wound-care booster, same day. Dirty wounds include puncture wounds, soil-contaminated cuts, animal bites, burns.[4] See /urgent-care-tetanus-cost for the urgent-care decision frame.
Tdap (preferred if not previously had Tdap), or Td as routine 10-year adult booster.[1] Pharmacy walk-in is fine for a routine booster. With insurance: $0. Cash: see the pharmacy comparison.
Tdap or Td as routine booster. The 10-year rule applies for clean minor wounds.[4] Pharmacy is fine if the wound itself does not need clinical attention.
Cost per branch
- DTaP for children: VFC-eligible kids free.[9] Insured kids typically $0 under ACA preventive. Cash: ~$25 to $40 per dose (pediatric series).[10]
- Tdap for adolescents and adults: cash $50 to $95, $0 with most insurance, GoodRx Boostrix from $60.86[5], Adacel similar.[6]
- Td for adults: cash $40 to $80, $0 with most insurance, GoodRx Tenivac from $51.93.[7][8]
- Pregnancy Tdap: $0 with insurance under ACA preventive maternity benefit; $0 with Medicaid; billed under prenatal care.
- Wound-care Tdap or Td: covered under Medicare Part B (post-injury) and most insurance as injury-related care.
Brand-name reference
- Tdap brands: Boostrix (GSK), Adacel (Sanofi)
- Td brands: Tenivac (Sanofi). MassBiologics discontinued Tdvax in 2024 (last lots orderable through 10 January 2025), so Tenivac is now the only Td vaccine available in the US.
- DTaP brands: Daptacel, Infanrix; combination products include Quadracel, Pediarix, Pentacel, Vaxelis
Pharmacies stock either Boostrix or Adacel for Tdap, and Tenivac for Td. Either Tdap brand is clinically interchangeable per ACIP. With Tdvax discontinued, CDC notes that Tdap is an acceptable substitute for Td in most situations, so a routine Td booster is often given as Tdap when Td supply is constrained.
Pregnancy Tdap, in detail
CDC ACIP recommends Tdap during every pregnancy at 27 to 36 weeks gestation, regardless of prior Tdap history.[3] The clinical aim is to transfer pertussis antibodies to the newborn before they can be vaccinated themselves. Pregnant adults are covered $0 under the ACA preventive maternity benefit and $0 under Medicaid. Most prenatal care providers administer Tdap during routine third-trimester visits; pharmacies also administer it on walk-in if the provider prefers that route.
Wound-care branch, in one paragraph
For a dirty wound (puncture, soil-contamination, animal bite, burn), CDC wound-management guidance recommends a tetanus-containing booster if the last dose was more than 5 years ago. For clean minor wounds, the threshold remains 10 years.[4] The 5-year rule is the single piece of guidance most clinic-vendor pages either gloss or omit. See /urgent-care-tetanus-cost for the decision frame and cost ranges.
