Tdap and Td Boosters in Adults: A Quick NP Guide

Tetanus, diphtheria, and pertussis may sound like diseases from the past, but adult vaccination is still critical. As a new nurse practitioner in primary care, you’ll need to know which booster to give, when to give it, and how to handle special situations like pregnancy or wound care.

Tdap vs Td: What’s the Difference?

• Tdap = Tetanus, diphtheria, acellular pertussis.

• Td = Tetanus, diphtheria (no pertussis component).

Adult Vaccination Schedule

• One dose of Tdap as an adult (if never received).

• Then Td or Tdap every 10 years for routine boosting.

📌 Clinical Pearl: You can substitute Tdap for Td at the 10-year mark — it’s safe and recommended.

Special Situations

Pregnancy

• All pregnant women should receive Tdap during each pregnancy, ideally between 27–36 weeks.

• Protects both mother and newborn (passive antibody transfer).

Wound Management

• If wound is clean & minor → give booster if last dose was >10 years ago.

• If wound is dirty or major → give booster if last dose was >5 years ago.

• If unsure or incomplete series → may need tetanus immune globulin (TIG).

Contraindications & Precautions

• Severe allergic reaction to a prior dose or vaccine component.

• History of encephalopathy within 7 days of pertussis vaccine (rare).

• Delay if moderate or severe acute illness.

Why It Matters in Primary Care

• Pertussis is still circulating and can be severe in infants and older adults.

• Tetanus is rare but deadly, often from contaminated wounds.

• Boosters are a simple, low-cost intervention with major impact.

Takeaway for New Nurse Practitioners

• Every adult needs one Tdap dose, then Td/Tdap every 10 years.

• Pregnant patients need Tdap each pregnancy (27–36 weeks).

• Don’t forget wound-based updates in the urgent care/clinic setting.

A quick vaccine check during wellness visits ensures adults stay protected.
