What is Adacel?

Adacel is a vaccine used to protect against diphtheria, tetanus, and pertussis for those who are over 10-years-old. A majority of those who are this age need only one Tdap shot to protect themselves from these illnesses.

Bacterial infections cause tetanus, diphtheria, and pertussis. Tetanus (lockjaw) results in an intense tightening of muscles, typically all over the body. It could cause "locking" of the jaw, and the victim would be unable to open their mouths or swallow. Tetanus is a cause of death in about one out of every 10 instances. Diphtheria results in a thick layer of bacteria on the throat, nasal passages, and airways. It could cause breathing difficulties, heart failure, paralysis, or even death.

Pertussis (whooping cough) can cause such severe coughing that it could cause problems with drinking, eating, or breathing. The symptoms can last for weeks and cause seizures, pneumonia (convulsions), brain damage, and even death.

Pertussis and diphtheria can be spread from one person to the next. Tetanus can enter the body via cuts or wounds.

Adacel is essential for health professionals or those who live close to babies less than 12 months old.

AdacelAdacelne involves exposing you to just a tiny amount of bacteria or a protein derived from the bacteria. This causes the body to develop an immunity to the illness. This vaccine cannot cure an active infection that has already started to manifest within your body.

Like all vaccines, Adacel could not protect against every disease.


In the majority of cases, Adacel is given in one dose. Follow your doctor's advice on receiving an additional dose, if required.You are still able to get the Adacel vaccine even if you've got an unaddressed cold. If you have an acute illness with fever or another type of illness, wait until you recover before receiving Adacel.

You shouldn't get Adacel if you've suffered an allergic reaction that was life-threatening to the diphtheria, tetanus, or pertussis vaccination. It is also not recommended to receive this vaccine if there was a neurological disorder that affects the brain within 7 days following the prior pertussis vaccination. Infection with diphtheria, pertussis, or tetanus can be significantly more hazardous to your health than obtaining an Adacel vaccine. But, as with all medicines, this vaccine could result in side effects; however, the likelihood of serious adverse effects is very low.

It is unclear if Adacel can harm a baby who is not yet born. But, it is possible that you will need the Adacel during your pregnancy to protect your baby's health from the pertussis. The youngest babies are the most susceptible to severe, life-threatening pertussis complications. Your doctor should determine if you are a candidate for this vaccine during your pregnancy.

If you are expecting and are a registered mother, your name could be included on the pregnancy registry. This is done to monitor the progress of your pregnancy and assess any consequences of Adacel for the newborn. It is unclear if the vaccine Tdap is passed into breast milk or if it can harm the nursing infant. Consult your physician if you are breastfeeding a baby. Adacel is not recommended for anyone under 10 years old. A different vaccine is offered to children under the age of 10.

Details On Dosage

Adacel is administered by injecting a shot into the muscle. It is administered in the clinic, in a doctor's office, or in a hospital. Adacel is typically only given once. Unless your physician's advice is different, it is not necessary to get an injection booster. Adacel is typically given once every 10 years.

What Happens If I Miss a Dose?

What Happens If I Overdose?

A dose of the vaccine that is too high is  unlikely to occur.
