Excerpt:
The contribution of natural immunity should speed up the timeline for returning fully to normal. With more than 8 in 10 adults protected from either contracting or transmitting the virus, it can’t readily propagate by jumping around in the population. In public health, we call that herd immunity, defined broadly on the Johns Hopkins Covid information webpage as “when most of a population is immune.” It’s not eradication, but it’s powerful.
Without accounting for natural immunity, we are far from Anthony Fauci’s stated target of 70% to 85% of the population becoming immune through full vaccination. But the effect of natural immunity is all around us. The plummeting case numbers in late April and May weren’t the result of vaccination alone, and they came amid a loosening of both restrictions and behavior.

Researchers from the Cleveland Clinic published a study this week of 1,359 people previously infected with Covid who were unvaccinated. None of the subjects subsequently became infected, leading the researchers to conclude that “individuals who have had SARS-CoV-2 infection are unlikely to benefit from COVID-19 vaccination.”
