The Tdap vaccine is a combination vaccine that provides protection against three serious bacterial infections:

1. Tetanus, commonly known as "lockjaw," causes painful muscle stiffness and spasms and can be life-threatening.
2. Diphtheria affects the respiratory system, potentially leading to breathing problems, heart failure, and paralysis.
3. Pertussis (whooping cough) is a highly contagious respiratory disease known for uncontrollable, violent coughing which can make breathing difficult.

The Tdap vaccine is administered to boost immunity against these diseases and plays a vital role in reducing the transmission of these infections, particularly to vulnerable groups like newborns and those who cannot be vaccinated for medical reasons.

While both Tdap and DTaP vaccines offer protection against the same infections, they are designed for different age groups and differ in their contents. DTaP is administered to infants and continues as a series of doses throughout early childhood. Tdap, in contrast, is a booster for older children, adolescents, and adults, with lower doses of diphtheria and pertussis components to reduce side effects while maintaining immunity.

The Tdap vaccine works by stimulating the immune system to produce antibodies that neutralise the toxins produced by the bacteria causing tetanus, diphtheria, and pertussis. For tetanus, it prevents the effects of Clostridium tetani toxins, which can cause severe muscle stiffness and spasms. For diphtheria and pertussis, it reduces respiratory symptoms and the risk of spreading these contagious diseases.

In Singapore, vaccination against diphtheria is legally required. As part of the National Childhood Immunisation Schedule (NCIS), children receive a series of DTaP vaccine doses from 2 to 18 months of age, followed by a Tdap booster at 10-11 years old. For adults, the Tdap vaccine is recommended for those with certain medical conditions, those who have not been vaccinated before, or if it has been over 10 years since their last dose.

The Tdap vaccine is typically administered as an injection, either into the muscle or just under the skin.

The recommended dosage for the Tdap vaccine is as follows:

If you're unsure of your vaccination status, it's best to consult with your doctor.

The immunity provided by the Tdap vaccine lasts approximately 10 years. Booster shots are recommended every decade to maintain protection.

Common side effects of the Tdap vaccine include mild reactions like dizziness, pain, or redness at the injection site, and headaches. These symptoms are generally short-lived, but you should consult a doctor if they persist or worsen.

In rare cases, severe allergic reactions might occur, such as swelling of the face or eyes, breathing difficulties, or widespread itchy rashes. Seek immediate medical attention if any of these symptoms are observed.
