Volunteers who are registered healthcare professionals are required to comply with the measles and diphtheria immunity requirements. This is because registered healthcare professionals have a professional duty to protect the health of their patients and the public, and thus should in principle be held to a higher standard compared to general volunteers.

Such volunteers will be exempted from the requirements if:

1. The volunteer’s work does not involve direct interaction with a patient and they do not work within the premises or conveyance of a healthcare institution which is used to provide services that involve direct interaction with patients.

2. Volunteers have documented proof that they are certified to be permanently medically unfit for vaccination (for measles and diphtheria); and

3. Volunteers who are employed or engaged (by Licensees or otherwise) for volunteering on a one-off basis.
