Diphtheria and Measles are the two mandatory by law in Singapore. An infant should undergo three doses of Diphtheria vaccine before turning one year old. To ensure continued defense against diphtheria, the first booster dose is administered at 18 months of age, followed by a top-up booster at 11 years of age.
The first dose of Measles vaccine is administered at the age of 12 months.
In addition to the mandatory vaccines, vaccinations such as BCG, hepatitis B, pertussis, tetanus, poliomyelitis are required for a child in order to enrol in Singapore’s primary school.
