A professor of epidemiology at the University of California, Berkeley’s School of Public Health, indicates that certain types of companies can require particular job-holders to be vaccinated against measles, according to a recent blog on NPR.

Hospitals, for one, are within their rights because of the high risks to patients with other ailments. According to the epidemiologist, that’s also why every medical and nursing school requires students to be vaccinated before they start training.

On the other hand, most office environments provide no palpable risk to employees. In between are public sites like Disneyland, which host many children and international visitors, as well as schools and daycare centers – where staffers probably should be immunized to protect themselves and others.

Taking the workplace issue a step further, a recent blog post from workforce.com ponders whether measles and other short-term viruses are protected under the Americans with Disabilities Act (ADA). The Equal Employment Opportunity Commission weighs in that private employers can compel their workforce to be vaccinated – provided they make allowances for ADA-defined disabilities and religious objections.
