What is the Boostrix vaccination?
Boostrix is a Tdap vaccine that protects you against three serious bacterial infections:
- T – Tetanus
- D – Diphtheria
- Ap – Acellular Pertussis
This 3-in-1 combination vaccine helps your immune system make antibodies and antitoxins against these diseases. When you get the Boostrix vaccination, your body learns to protect itself against the diseases without you actually getting sick.
Boostrix is not a treatment for these diseases—it's a preventive measure to keep you safe. As you grow from childhood into adolescence and adulthood, your immunity from earlier vaccinations gradually decreases. That's why Boostrix serves as an important booster dose to maintain your protection.
What is this medicine used for?
Boostrix boosts immunity for three life-threatening diseases:
Diphtheria
Diphtheria is a bacterial infection that affects your throat and upper airways. It produces toxins that can lead to severe complications like heart and nerve damage. Getting vaccinated helps you avoid these risks and prevents outbreaks.
Tetanus
Tetanus, also known as lockjaw, is caused by bacteria found in soil, dust, and manure. These bacteria can enter your body through cuts or wounds, releasing toxins that cause intense muscle stiffness and spasms. The vaccine offers you the best protection against tetanus.
Whooping cough (pertussis)
Whooping cough is a highly contagious respiratory infection caused by the Bordetella pertussis bacteria. It can cause severe coughing fits, difficulty breathing, and complications—especially in infants, young children, and older adults. Boostrix helps you maintain immunity and reduce the risk of spreading the disease to others.
When to get the Boostrix vaccine?

As an adult:
You should get one booster dose if you haven't had a tetanus, diphtheria, or pertussis booster in the past 10 years.
This is especially important if you work in healthcare, are a caregiver, or are often around babies.
If you are pregnant:
You’re advised to get the whooping cough vaccine during pregnancy between 27 and 36 weeks.
The vaccine helps protect your baby from whooping cough, as the antibodies you develop will be passed to your baby before birth.
If you get a dirty wound:
If you have a deep or infected wound and haven't had a tetanus shot in the last 5 years, you should get a dose of Boostrix to prevent you from getting tetanus.
If you have questions about the Boostrix vaccine or whether it's suitable for your health needs, it's best to speak with a qualified healthcare professional. You may contact Thomson Medical to arrange a consultation and receive guidance tailored to your medical needs.
What precautions should you follow before receiving the Tdap vaccine?
Before getting your Tdap vaccine, it’s important to share your medical history with your healthcare provider. This information helps ensure the vaccine is safe and suitable for you. Be sure to inform them if:
- You’ve had an allergic reaction to a previous dose of the Tdap vaccine or any of its components.
- You are pregnant, planning to conceive, or currently breastfeeding, your provider can advise you on the best timing for vaccination.
- You are currently taking medications, including over-the-counter drugs or supplements, which might interfere with the vaccine.
- You experienced a serious reaction after a previous dose, particularly affecting the nervous system, such as fits (seizures), altered mental status, or loss of consciousness.
- You are currently unwell or having a fever; you may need to delay your shot until you’ve recovered.
- You have a bleeding disorder or are taking blood-thinning medications, as this may affect how the injection is administered.
Being open about your health condition allows your healthcare provider to take the right precautions and provide you with the appropriate care.
Are there any side effects?
Like all vaccines, you may experience some side effects after receiving your Boostrix vaccination.
Common side effects

If any side effects persist or worsen, it’s important to consult your doctor or a healthcare professional for further guidance.
FAQ
How often do you need Boostrix as an adult?
You should receive a Tdap booster vaccine, such as Boostrix, every 10 years to maintain your antibody protection against diphtheria, tetanus, and pertussis in individuals aged 10 and older.
If you experience a wound or injury, or if you are in the third trimester of pregnancy, your doctor may recommend an earlier booster to ensure your antibody levels are high enough to protect your newborn baby from pertussis.
Is the Boostrix injection necessary for you?
Yes, it's essential to maintain your immunity against diphtheria, tetanus, and pertussis, especially if you're at risk or in close contact with vulnerable people, like infants or elderly individuals.
Who should get the Tdap vaccine?
In Singapore, diphtheria vaccination is required by law. According to the National Childhood Immunisation Schedule (NCIS), children receive a series of DTaP vaccine doses between 2 and 18 months of age, with a Tdap booster given at 10 to 11 years old.
For adults, the Tdap vaccine is recommended if:
- You have certain medical conditions
- You have never received the vaccine before
- It has been more than 10 years since your last Tdap doses
Do I really need a tetanus shot every 10 years?
Yes, your antibody protection decreases over time. Getting a booster every 10 years ensures you stay protected against tetanus, which can cause serious complications requiring extensive medical treatment. This is particularly important after injuries that might increase your risk of active infection.
Is the Boostrix injection painful?
The Boostrix injection may cause mild pain, redness, or swelling at the injection site, which is common with many injectable vaccines. This discomfort is usually temporary and goes away within a few days. Severe pain or serious reactions are rare. Using a cold pack can help ease soreness after vaccination.
What is the alternative to the Boostrix vaccine?
You have several alternatives to Boostrix, including other Tdap vaccines such as Adacel. If you only need protection against tetanus and diphtheria, you might consider Td vaccines like Tenivac. Regardless of which vaccine you choose, it's important to keep your immunisations on time to minimise potential adverse effects and maintain continuous protection.
