Vaccinating people who have had covid-19: why doesn’t natural immunity count in the US? [BMJ feature.] The substantial number of infections, coupled with the increasing scientific evidence that natural immunity was durable, led some medical observers to ask why natural immunity didn’t seem to be factored into decisions about prioritising vaccination. “The CDC could say [to people who had recovered], very well grounded in excellent data, that you should wait 8 months,” Monica Gandhi, an infectious disease specialist at University of California San Francisco, told Medpage Today in January. “Many of us were saying let’s use [the vaccine] to save lives, not to vaccinate people already immune,” says Marty Makary, a professor of health policy and management at Johns Hopkins University. Real world data have also been supportive. Several studies (in Qatar, England, Israel, and the US) have found infection rates at equally low levels among people who are fully vaccinated and those who have previously had covid-19. But as the delta variant and rising case counts have the US on edge, renewed vaccination incentives and mandates apply regardless of infection history.
