Tetanus, diphtheria, and pertussis or whooping cough: the three life-threatening bacterial diseases. The question is, how can you protect yourself from these three troubles? The answer is easy: Tdap.

Tdap is a combination vaccine that protects preteens and adults against these three diseases: tetanus, diphtheria, and pertussis. Especially pertussis or whooping cough as pertussis is perennial and spreading continuously in the United States compared to the other two diseases. We will explore in this article all you need to know about Tdap: when you should take it, how often you should take it, and how long does a Tdap vaccine last.

What is the Tdap Vaccine?

Tdap is the combination vaccine that stands for tetanus (T), diphtheria (D), and acellular pertussis (aP). Tdap is different from the DTaP vaccine. DTaP is for infants and children younger than 7 years who get the vaccine in five doses. However, Tdap is primarily for adults and children above 7 years old.

Earlier, in the US, tetanus, diphtheria, and whooping cough were common and fatal diseases. In time, though routine vaccinations discard the danger of tetanus and diphtheria infection, no vaccine for children above 6 years and adults was there to protect against pertussis. Due to this reason, there were outbreaks of whooping cough in several areas.

Finally, in 2005, the Tdap vaccine became available for everyone: preteens, adults, and children above 7. Now, it is successfully providing the best protection against the three diseases. Tdap is an inactive vaccine; it uses dead bacteria. Therefore, it can’t cause any diseases like live bacterias. Before we learn how long a Tdap vaccine lasts, let’s know more about the three diseases Tdap fights.

Tetanus is a non-contagious disease that enters the body through a wound or a cut. These bacterias usually dwell in soil, dust, and fertilizer that affects your brain and nervous system. Tetanus can also cause excruciating muscle spasms or tightening of the jaw muscle. Due to this reason, tetanus gets its popular name, “Lockjaw.”


Diphtheria is a highly contagious disease that can cause difficulty breathing, heart failure, paralysis, and death. The bacteria causing diphtheria usually transmits through respiratory droplets, coughing, sneezing, and in many cases, from contact with open sores or ulcers.

Pertussis or Whooping Cough

Whooping cough or pertussis is a highly contagious bacterial infection that can lead to severe breathing problems, especially in newborns. The bacteria usually attack the respiratory system that initially looks like a common cold. However, the cold and cough soon become intense and uncontrollable, creating the noise “whoop” while breathing after the cough.

Infants are more prone to get affected by the disease than adults. However, they often get the infection from adults. DTaP can protect children against pertussis; however, the protection declines over time. Here comes Tdap maintaining the safety circle of immunity around them.

How Long Does A Tdap Vaccine Last?

Tdap is an effective vaccine against tetanus and diphtheria. However, effective, it’s not totally perfect against pertussis.

Research suggested that Tdap effectively protects everyone against tetanus and diphtheria for 10 years. However, against pertussis, they offer sufficient protection within the first 2 years only. After that, the defense starts to decline gradually.

CDC records that Tdap fully protects about 7 in 10 people in the first year after getting the vaccine. However, Tdap protects about 3 or 4 in 10 people in the fourth year. The effectiveness of the protection declines each year gradually.

On the other hand, Tdap taken during pregnancy can effectively protect more than 3 in 4 babies from getting whooping cough. Thanks to the vaccine, about 9 in 10 babies suffering from whooping cough don’t need serious hospital care due to the protection during pregnancy.

Therefore, keep your vaccination routine up to date if you want to keep yourself and your family safe and protected against these bacteria. Contact MyConciergeMD, to get proper administration and maintenance of your vaccination routine to keep you healthy.

When and How Often Can You Get The Tdap Vaccine?

Doctors usually recommend a Tdap vaccine depending on your age, condition, and vaccination history.

Preteens and Teens

Preteens usually get one shot of Tdap between the age of 11 and 12 years. However, the catch-up vaccination observes the following-

Ages 7-18 years (who haven’t completed full vaccination with DTaP)
