1. It's a leaky vaccine, it doesn't stop transmission.
2. These healthcare workers either have natural immunity and are vaccinated. It doesn't make sense to continually force them to bi-annual boosters, like they soon will probably do.
3. We know that the majority of ppl who get it don't get hospitalized, plus there are a variety of ways to greatly reduce your odds of hospilaztion (boost your immune system, get in shape, treatments like monoclonals and covid pills).
It's silly to force that 26 y/o healthy nurse to take multiple boosters, when she might have better odds w/ covid than her 3x vaxxed 70 yo hospital admin that has a comorbidity.
