It's a choice, but in healthcare roles it shouldn't be IMO. You are working with the most vulnerable group to infectious illnesses of all kinds and present a risk to them when unvaccinated for various illnesses and it's a total betrayal of medical ethics IMO to risk wander around spreading disease when you can be vaccinated and protect them and yourself. When your choice presents a risk of your patient's health or ability to survive their hospitalization i.e. the ability to do your job without being a risk, it's quite another thing. Your choice shouldn't potentially kill or maim people who are trusting you to do your job.
I know someone whose elderly dad went into a hospital around my way for a needed and already very delayed back operation last December. Quarantined for two weeks prior to entering the hospital, tested negative, then was infected in the hospital post-operation and subsequently nearly died of COVID. Should have been out within a week, spent over a month in there instead and still is suffering the after effects of the illness. Unacceptable to begin with back then, and clearly transmitted by staff as no patients were allowed in without mandatory quarantine and testing, but it would be ten times as unacceptable now, given staff have better means to protect themselves from the disease.
I have two relatives in the NHS, one in a lab role, and another one who tends to dabble a lot with conspiracy shit, and even he manned up and got both vaccinations after some whining. The first in December last year. His job takes him miles around the hospital every day, in and out of wards, plus handling food, and if he were infected with COVID he'd be the equivalent of Typhoid Mary taking out patients left, right and centre, so he got vaxxed. Thankfully.
The fertility thing shows they've been reading crank sites. There's no evidence whatsover for any of the vaccines impeding fertility. There's not even a medically possible pathway known that could even do it. It really bothers me that people in healthcare would begin the swallow that scare story, because it implies kneejerking in fear rather than proper investigation, and reading nonsense sites rather than seeking out actual credible medical sources. Shouldn't we at least expect people in healthcare to read proper medical sources?
It's like the bloodclot thing, people going crazy about some super rare events that aren't necessarily caused by the vaccine, when other very commonly used drugs such as various contraceptive pills and the blood thinner Heparin have much, much larger incidence of thrombosis. Heparin 1000x more commonly. Yet, nobody suddenly decides to eschew blood thinners or the pill when indicated despite these being known risks, or form a far reaching world conspiracy around them. Probably half the people squawking about AZ or whatever are taking daily prescribed drugs with higher chances of causing a blood clot.
