Yes. I don’t know how you can see these things, be traumatised by them and still not want to prevent others from suffering like those patients and their families did.
Personal choice when it comes to your body, yes of course. But this affects everyone. Also you do not have to work for the NHS, plenty of private practices about if you don’t want the vacccine.
You have to have the Hep C vaccine to work in patient facing care in the NHS, no exceptions other than allergies. I don’t see why this should be any different. It’s to protect both yourself and the wider community.
