Difference Between TDaP and DTaP

DTaP is a vaccine that helps children younger than age 7 develop immunity to three deadly diseases caused by bacteria: diphtheria, tetanus, and whooping cough (pertussis). Tdap is a booster immunization given at age 11 that offers continued protection from those diseases for adolescents and adults.

Are DTP and Tdap the same?

DTaP produces fewer side effects and is a safer version of an older vaccine called DTP, which is no longer used in the United States. Tdap vaccine is licensed for people 10 years through 64 years of age. Tdap contains a lower concentration of diphtheria and pertussis toxoids than DTaP. Tdap is given at 11-12 years.

Do you need Tdap if you had DTaP?

Do you need Tdap if you've had DTaP? Yes. Tdap is often used as a booster. Anyone over age 7 who needs diphtheria, tetanus, and whooping cough vaccines gets Tdap.

Do adults need Tdap booster?

Every adult should get the Tdap vaccine once if they did not receive it as an adolescent to protect against pertussis (whooping cough), and then a Td (tetanus, diphtheria) booster shot every 10 years. In addition, women should get the Tdap vaccine each time they are pregnant, preferably at 27 through 36 weeks.

Why is DTP no longer used?

In the US by the mid-1980s, lawsuits related to vaccine safety led several manufacturers to withdraw their DTP vaccines and paved the way to the US National Childhood Vaccine Injury Act in 1986. This act provides funds to compensate for adverse events following immunization.

Is it OK to get Tdap twice?

Studies looked at the safety of giving multiple Tdap doses because there is a theoretical risk for severe local reactions (called hypersensitivity) if the tetanus component of the vaccine is given too often.

How often do Grandparents need Tdap?

A single shot of Tdap is recommended in place of your next Td (tetanus, diphtheria) booster, which is given every 10 years.

How soon after Tdap can I be around baby?

All close contacts to the newborn should be vaccinated with the annual influenza vaccine at least 2 weeks before meeting the baby. They should also have had Tdap in the last 10 years. If they have not received that vaccine, they should get a Tdap booster at least 2 weeks before meeting the baby.

What happens if you get Tdap too soon?

Answer: Getting a tetanus booster dose early is not harmful. However, booster doses of tetanus-containing vaccines given too frequently may cause an increased local reaction. Your immunizing health care provider can make a recommendation for you.

Is it bad to get Tdap before 10 years?

This is especially true in patients at increased risk of pertussis or its complications; the benefit of a single dose of Tdap at an interval of less than 10 years will likely outweigh the risk of adverse reactions to the vaccine. In addition, an interval as short as two years between Td and Tdap is considered safe.

Why does the Tdap shot hurt so much?

The pain you are experiencing is usually soreness of the muscle where the injection was given. This pain is also a sign that your immune system is making antibodies in response to the viruses in the vaccine.

How long does Tdap vaccine last for adults?

Studies estimate that diphtheria toxoid-containing vaccines protect nearly all people (95 in 100) for approximately 10 years. Protection decreases over time, so adults need to get a Td or Tdap booster shot every 10 years to stay protected.

Does my husband need Tdap vaccine?

All adults and adolescents in contact with the baby need to get the flu and Tdap vaccines. This includes: partners, fathers, grandparents, caregivers, and siblings. The flu vaccine is recommended every year. Unless you are pregnant, the current Tdap recommendation is once during adulthood (after 19 years old).
