By law, there are a number of vaccinations that are compulsory for children to recieve such as Diptheria must be completed before a child turns one year old whilst measles must be completed before they turn two. Vaccines against diphtheria and measles is the responsibility of the parent or guardian of the child. In primary school, kids will be vaccinated against a variety of infectious diseases such as BCG, pertussis, tetanus, poliomyelitis, mumps, rubella and hepatitis B. http://sg.theasianparent.com/are-vaccinations-mandatory-can-i-opt-out-of-it/
