Those old-fashioned simian adenovirus vectors still have their good points. Good news.
Health workers not vaxxing is about as cult-crazy as surgeons not washing their hands. Just fire these shitheads and hire some people who actually know something about medicine. When you have people who are unable to grasp why we no longer suffer (or rarely suffer) from typhus, polio, smallpox, tetanus, diphtheria, pneumococcal, rubella, meningococcal, etc, then you are looking at minds in the powerful grip of a death cult and which are a threat to patient welfare.
Fuck them and the horse dewormer they rode in on.
