Have you ever stepped on something like a rusty nail or a piece of metal and got injured? When that happens, we immediately see a doctor and get an Anti-Tetanus shot to prevent tetanus, right? Similarly, we are given many vaccines from childhood to protect us from a number of dangerous diseases. Today, we are going to talk about the only vaccine that protects us from three such very dangerous, and sometimes fatal, diseases. That is the Tdap vaccine . It will be very important for you and your family to be aware of this.
Tdap is a vaccine against what three diseases?
Simply put, Tdap is a combination vaccine that protects against three diseases in one shot. The three letters in its name represent the three diseases. Let's take a look at what they are.
| Letter | Disease | A simple explanation |
|---|---|---|
| T | Tetanus (lockjaw) | This is also called "lockjaw." This causes the muscles in the body, especially around the neck and jaw, to tighten and become painful. You may not be able to open your mouth, breathe, or swallow. If left untreated, it can even lead to death. |
| d | Diphtheria | This causes a thick coating to form at the back of the throat. This can cause breathing difficulties, heart attacks, paralysis, and even death. |
| ap | Acellular Pertussis (Whooping Cough) | This causes a severe, persistent cough that makes it difficult to breathe, eat, or even drink. It can be life-threatening, especially for infants and young children. |
The most important thing is that the Tdap vaccine is only given to children over 7 years of age, adolescents, and adults. There is another vaccine (DTaP) that is given to children younger than that for the same diseases.
What do the uppercase and lowercase letters in the names of these vaccines mean?
You've probably heard several names like DTaP, Tdap, and Td. While this may seem a little confusing, it's actually quite easy to understand.
Simply put, a capital letter in the name indicates that the vaccine contains a full-strength dose of the vaccine for that disease. A lowercase letter , like the 'd' and 'p' in Tdap, indicates that it contains a smaller dose of the vaccine for tetanus and pertussis. This smaller dose is enough to give a booster dose to young and old people.
The 'a' in Tdap and DTaP stands for 'acellular' . This means that the vaccine contains only a portion of the whooping cough bacteria, not the entire bacteria. This makes the risk of side effects much lower.
Who should get the Tdap vaccine?
We need to be clear about who needs this vaccine. It is generally recommended for the following people:
- Children over 7 years of age: If they were unable to complete the vaccine series as a child or did not receive it at all, they are given the Tdap vaccine.
- Children between the ages of 11-12: One dose is given to boost immunity from childhood vaccinations.
- Pregnant mothers: If you are pregnant, it is essential to get the Tdap vaccine during the third trimester of pregnancy. We will talk about this further.
- Adults: Any adult who has never received the Tdap vaccine before should get one dose. After that, it is important to get a booster dose every 10 years to maintain immunity.
Why is it especially important to get the Tdap vaccine during pregnancy?
When a pregnant mother is told to get this vaccine, she may feel a little scared. "Will this affect the baby?" You may wonder. But this is actually a great protection for both you and your unborn baby.
Imagine, when you get this vaccine during pregnancy, your body produces antibodies against measles, mumps, and especially whooping cough. These valuable antibodies are also passed on to your baby through the placenta.
The biggest advantage of this is that the baby is protected from whooping cough from the moment it is born. Because a baby is not protected from whooping cough until about two months after they start their own vaccination series. This disease is very dangerous if a baby gets it. So the vaccine you get is like the first protective shield your baby gets.
Research has shown that getting this vaccine during pregnancy does not pose any risk of premature birth or low birth weight. Therefore, get it without any fear, as per your doctor's advice.
Who should not get the Tdap vaccine?
Some people are not suitable for this vaccine. If you have a serious medical condition, it is best to postpone getting the vaccine until you are well.
Also, if you have any of the following conditions, you should definitely talk to your doctor before getting the vaccine:
- If you have had a severe allergic reaction after receiving a previous Tdap vaccine.
- If you have previously experienced severe pain or swelling after receiving a vaccine for shingles or shingles.
- If you have experienced a coma, loss of consciousness, or seizures after receiving a whooping cough vaccine.
- If you have frequent seizures .
- If you have a neurological condition called Guillain-Barré syndrome (GBS) .
Side effects of the vaccine and what to watch out for
As with any vaccine, some minor side effects may occur after receiving the Tdap vaccine. These usually go away within a day or two.
Common minor side effects:
- Pain, redness, or swelling where the injection was given
- Fatigue
- Headache
- A slight fever
- Nausea and vomiting
- Stomach ache
Severe symptoms that require immediate medical attention:
These are very rare, but if you experience a severe allergic reaction like this, go to the nearest hospital emergency room (ETU) immediately.
- Skin rashes (hives) and swelling of the face and throat
- Difficulty breathing
- Heart palpitations
- Dizziness
- Lifeless body
Some other important facts about the Tdap vaccine
- Where do you get this?
You can get the vaccine from your family doctor, government hospital clinics, and private hospitals. For pregnant women, the vaccine is also available through the local Medical Officer of Health (MOH) office.
- Can this be taken with other vaccines?
Yes. There is no problem getting the Tdap vaccine on the same day as other vaccines, including the COVID-19 vaccine. But always talk to your doctor about it and get advice.
- Do I need to get a booster every 10 years?
Yes, absolutely. The immunity from the vaccine can wane over time. So getting a booster dose every 10 years will give you long-term protection against these dangerous diseases.
