I don't understand why you refuse to acknowledge that the main reason a healthcare provider, like Becca's employer, requires vaccines. It has almost NOTHING AT ALL TO DO WITH BECCA'S RISK OF DEATH!!!! (although see below). They require vaccines, primarily, because vaccines 1) reduce infections, and 2) therefore, reduce the risks that Becca et al. will get a COVID case, often asymptomatic, then spread it to patients/clients and KILL THOSE PATIENTS.
And the problem is for an employer, employees are shitty, terrible, awful at assessing their own risks. So you saw hospitals full this Fall with people who deliberately avoided vaccines, believed they were not at risk, and they were wrong, they were overweight, had undiagnosed or diagnosed high blood pressure - actually the biggest risk factor - or had other conditions that resulted in a serious case, and they were in ICUs running up 6 figure tabs, and way, way too often dying. About 90% of them locally were unvaccinated - 90% believed they were bullet proof with COVID. So they failed at risk evaluation, and we all paid the price.
Just on the business end, do you want to let employees do a terrible job of assessing their own risks, and then pay out $100k per case, or require a 'free' vaccine? If that financial risk was related to a $100k 18 wheeler, and they could fix the brakes for $20 or assume the small but easily quantifiable risk of a crash totaling the truck and killing the driver, and putting other drivers at higher risk of death, what do you think every employer on planet earth would do? Fix the brakes - 100% of them, at least 100% of them not total idiots, verifiable incompetents. And you'd have employers do the opposite with COVID vaccines......
