Caregivers and health workers can now return to hospital services, after refusing to be vaccinated during the Covid-19 outbreak. Good news for some, but apprehension for others, who will face the disapproval and concern of their department heads.

This is the case of Gilles Pialoux, head of the infectious diseases department at Tenon Hospital in Paris. "Explain to me how you are going to reintegrate unvaccinated people into bone marrow transplant services, for example," he said.
