What age is Tdap for adults? A guide to vaccination recommendations

According to the Centers for Disease Control and Prevention (CDC), cases of pertussis, or whooping cough, still affect thousands of people annually in the U.S. Understanding what age is Tdap for adults is a crucial first step toward protecting not only your own health but also the health of those around you, especially vulnerable infants.

Quick Summary

All adults aged 19 and older who have not received a Tdap vaccine should get one dose, followed by a Td or Tdap booster every 10 years to maintain immunity.

Key Points

• Initial Dose: All adults aged 19 years and older who have not been previously vaccinated with Tdap should receive a single dose.

• Decennial Booster: A Tdap or Td booster shot is recommended every 10 years for all adults to maintain protection.

• Pregnancy: The Tdap vaccine should be administered during every pregnancy, ideally between 27 and 36 weeks' gestation, to protect newborns.

• Older Adults: The CDC advises that adults 65 years and older, who have not received a Tdap dose, should get one.

• Wound Management: Tdap is the preferred vaccine over Td for wound management in adults who have not had a previous Tdap dose.

• Disease Prevention: The primary benefit of Tdap over Td is the added protection against pertussis, which is highly contagious and particularly dangerous for infants.

Initial Tdap Dose: The Adult Foundation

For any adult aged 19 years or older who has never received a Tdap vaccine, the recommendation is to get a single dose as soon as possible. This is particularly important for adults who were not vaccinated during their adolescence. Unlike the Td (tetanus and diphtheria) vaccine, the Tdap vaccine provides essential protection against pertussis, a highly contagious respiratory illness. This initial dose helps bridge the immunity gap from childhood vaccinations and protects against current outbreaks.

The Every-10-Year Booster: Maintaining Protection

Following the initial Tdap dose, maintaining protection is a lifelong process. The CDC recommends a booster shot every 10 years throughout adulthood. For these routine boosters, a Tdap vaccine can be used, but a standard Td vaccine is also an option. Choosing Tdap for subsequent boosters is often advised, especially for individuals who interact with infants or work in healthcare settings, due to its continued protection against pertussis. For those needing a tetanus shot due to a serious wound, Tdap is often the preferred vaccine if the last booster was more than five years ago.

Special Considerations for Adult Tdap Vaccination

Tdap during Pregnancy

One of the most critical recommendations is for pregnant individuals. The CDC advises that a dose of Tdap should be received during every pregnancy, ideally during the early part of the third trimester (between 27 and 36 weeks' gestation). This provides the infant with a crucial protective antibody boost from the mother before birth, helping to safeguard them from pertussis during their most vulnerable first few months of life, before they can receive their own immunizations.

Adults Ages 65 and Older

For older adults, staying up-to-date on vaccinations is key to healthy aging. While Tdap is licensed for individuals up to age 64, those 65 years and older can still receive it. Healthcare providers are encouraged not to miss an opportunity to vaccinate adults in this age group, using a Tdap product like Boostrix when feasible. This ensures they have the same robust protection against tetanus, diphtheria, and pertussis.

Catch-Up Schedule for Adults with Incomplete Records

For adults with incomplete or unknown vaccination histories, a catch-up schedule is necessary. This typically involves a series of shots to establish full immunity.

1. First Dose: A single dose of Tdap should be given as the first shot in the series.
2. Second Dose: A dose of Td or Tdap should follow at least four weeks after the first dose.
3. Third Dose: Another dose of Td or Tdap is given six to twelve months after the second dose.

Potential Side Effects and What to Expect

As with any vaccine, Tdap can cause minor side effects. These are typically mild and go away on their own within a few days.

• Pain, redness, or swelling at the injection site.
• Body aches or fatigue.
• A low-grade fever.
• Headache.

Serious side effects are rare. It is important to discuss any concerns or severe reactions with a healthcare provider.

Tdap vs. Td: A Comparison

Feature	Tdap	Td
Protects Against	Tetanus, Diphtheria, Pertussis (whooping cough)	Tetanus, Diphtheria
Recommended For	Initial dose for all adults 19+, pregnant people, and close contacts of infants	Routine every 10-year booster for adults, and wound management
Benefit	Provides broader protection, including against whooping cough	Protects against tetanus and diphtheria only

Conclusion

Knowing what age is Tdap for adults is a crucial part of a proactive healthcare strategy. With a simple, one-time initial dose for all unvaccinated adults over 19, followed by regular 10-year boosters, individuals can significantly reduce their risk of contracting and spreading serious diseases like tetanus and pertussis. For pregnant women and those caring for infants, the Tdap vaccine offers an additional layer of protection for the most vulnerable members of our communities. Always consult with a healthcare provider to determine the best vaccination schedule for your personal health needs.

Frequently Asked Questions

Do I need a Tdap shot if I had one as a child?

Yes, even if you received a Tdap or DTaP vaccine as a child, adults need a booster shot. The CDC recommends one Tdap dose for adults who have not had one before, followed by a Td or Tdap booster every 10 years.

Can adults over 65 get the Tdap vaccine?

Yes, while some Tdap products were initially only licensed for younger adults, the CDC recommends that adults aged 65 and older should not miss the opportunity to get a Tdap vaccine. Your doctor can recommend the best option.

How often do adults need a Tdap booster?

Following your initial Tdap dose, you should receive a Td or Tdap booster shot every 10 years to ensure continued protection against tetanus and diphtheria.

Is the Tdap vaccine safe for pregnant women?

Yes, the Tdap vaccine is safe and highly recommended for pregnant women. It is given during each pregnancy to pass protective antibodies to the newborn, offering them early protection against whooping cough.

What is the difference between the Tdap and Td vaccines for adults?

Tdap is a combination vaccine that protects against tetanus, diphtheria, and pertussis (whooping cough). Td only protects against tetanus and diphtheria. Tdap is generally preferred for the initial adult dose and during pregnancy due to its protection against pertussis.

What should I do if I have a deep wound and haven't had a tetanus shot in a while?

For adults with a serious or deep wound, Tdap is the preferred tetanus-containing vaccine if your last dose was more than five years ago and you have never had a Tdap shot. Consult a healthcare provider for prompt treatment.

Why is adult Tdap vaccination important for senior care?

Protecting seniors with the Tdap vaccine is crucial because it not only prevents them from getting sick but also reduces the risk of transmitting pertussis to others, including vulnerable young grandchildren.
