That, and recognize the natural immunity of those recovered from COVID. For those who work with the most vulnerable populations (oncologists, infusion centers, dialysis centers, nursing homes, etc), they should probably require testing regardless of immune status. It's possible Omicron will make this mostly unnecessary.
Yes,that’s true.It’s my understanding that natural immunity is accepted in some countries as a substitute for vaccination. I’d love to get a top Infectious Disease Specialist at Harvard,Columbia,Hopkins,Mayo Clinic or Stanford drunk and ask him/her about natural immunity resulting from having recovered from the virus.
