There are morally acceptable vaccines:

Yes, in particular the Covaxin from India. Nevertheless, it is my understanding that since they're not approved by the FDA/CDC, they don't "count" towad the jab requirement in the US. I recall hearing that somewhere. In any case, if these bishops / priests got the non-compromised jabs, then I could definitely see making a case for it ... when the faithful would require the Sacraments ... but not really for a speaking tour.
I've discussed this elsewere that if I had the option of taking a jab like Covaxin, which is an attenuated virus jab, assuming they'e not lying about it, I would feel morally required to take it to continue supporting my family. In essence, it's the equivalent of catching COVID naturally.
