Judging from how a former friend who was a registered nurse in surgery or recovery talked about her colleagues years ago now I wonder how many have been double jabbed. She used to talk about consultant friends and colleagues who used to talk about vaccines not working or causing the condition they're designed to prevent. I used to know a few NHS workers and they were all negative about their job, colleagues and the system. Mind you they were quite happy getting the extra lists and effect adding 50% to their paypacket each month due to the incompetence of a colleague, systems, hospital or trust.
I'm sure NHS workers tend to remember the negative more than the positive, but it was furness general back when it hit the headlines so they could have a point.
