The Pfizer and Moderna vaccines both demonstrated about 95% efficacy and no serious safety concerns. CDC guidelines on prioritization of vaccine recipients list healthcare first responders and nursing home residents in Group 1a. Group 1b is non-healthcare essential workers, like teachers. Group 1c is seniors over 65, and adults of any age with co-morbidities.

Some adults may not receive a shot until March or so.

Given that fact, is it any surprise that the well-heeled are willing to pay for a faster vaccination?
