Measles and diphtheria are serious infectious diseases, and vaccinations against the two diseases are mandated under the Infectious Diseases Act 1976 for all children residing in Singapore.

There is a need to ensure high vaccination coverage or immunity among workers in healthcare, to minimise the risk of disease outbreak and spread of the diseases to patients, and other healthcare workers.

The measles outbreaks in 2019 globally further highlight the vulnerability of not being protected against the disease. It is important to ensure that all healthcare workers who are clinically eligible for the vaccines are protected against these serious infectious diseases through up-to-date vaccinations.
