Epidemiologists estimate over 160 million people worldwide have recovered from COVID-19. Those who have recovered have an astonishingly low frequency of repeat infection, disease, or death. That immunity from prior infection protects many people now where vaccines are not yet available.
The range of reduction of re-infection from COVID-19 was between 82% to 95% among six studies that encompassed nearly 1 million people conducted in the U.S., the U.K., Denmark, Austria, Qatar, and among U.S. Marines. The study in Austria also found that the frequency of re-infection from COVID-19 caused hospitalization in only five out of 14,840 (0.03%) people and death in one out of 14,840 (0.01%).
Moving forward, policymakers should include natural immunity as determined by an accurate and reliable antibody test or the documentation of prior infection (previous positive PCR or antigen test), as evidence of immunity equal to that of vaccination. That immunity should be given the same societal status as vaccine-inducted immunity.
