Diphtheria Tetanus Polio (dT-IPV)

The dT-IPV vaccine (Revaxis) is a combination vaccine that provides protection against diphtheria, tetanus and polio. It is typically given to infants and young children as part of routine immunisation schedules in many countries and as a booster vaccine as a travel vaccination.

Here’s a brief overview of the diseases that this vaccine protects against:


Diphtheria is a bacterial infection caused by Corynebacterium diphtheriae. It primarily affects the respiratory system, causing a thick coating to form in the throat, which can lead to severe breathing difficulties and even death.


Tetanus, also known as lockjaw, is caused by the bacteria Clostridium tetani. It enters the body through wounds and produces a toxin that affects the nervous system, leading to muscle stiffness and spasms. Tetanus can be life-threatening.


Polio, short for poliomyelitis, is a highly contagious viral disease caused by the polio virus. It primarily affects the nervous system, potentially causing paralysis, muscle weakness, and in severe cases, respiratory failure. Polio has largely been eradicated in many parts of the world due to widespread vaccination efforts.

The dT-IPV vaccine combines the antigens from diphtheria and tetanus toxoids with inactivated polio virus strains to stimulate the immune system to produce protective antibodies against these diseases. It is typically administered as a series of doses starting in infancy, with booster doses recommended at specific intervals.

Side Effects
Common side effects of the Revaxis vaccine are generally mild and typically resolve on their own. These side effects may include:
1. Redness, swelling, or pain at the injection site: This is the most common side effect and usually goes away within a few days.
2. Fever: A low-grade fever may occur after receiving the vaccine but it is generally short-lived.
3. Headache: Some individuals may experience mild headaches after vaccination.
4. Fatigue: Feeling tired or fatigued is another possible side effect but it is usually temporary.
5. Muscle aches: Mild muscle aches or discomfort can occur following vaccination.

Serious side effects from the Revaxis vaccine are rare. However, as with any vaccine, there is a small risk of an allergic reaction. Signs of a severe allergic reaction may include difficulty breathing, swelling of the face or throat, hives or a fast heartbeat. If any of these symptoms occur after receiving the vaccine, immediate medical attention must be sought.

It’s important to note that no vaccine offers 100% protection and individual immune responses can vary. However, the Revaxis vaccine has proven to be highly effective in reducing the incidence and severity of diphtheria, tetanus and polio.

It’s important to follow the recommended vaccination schedule and consult with healthcare professionals for specific information about the dT-IPV vaccine, including its availability, potential side effects, and any precautions or contraindications associated with the vaccine.
