Sound data from the CDC has been especially lacking on natural immunity from prior Covid infection. On Aug. 25, Israel published the most powerful and scientifically rigorous study on the subject to date. In a sample of more than 700,000 people, natural immunity was 27 times more effective than vaccinated immunity in preventing symptomatic infections.
Despite this evidence, U.S. public health officials continue to dismiss natural immunity, insisting that those who have recovered from Covid must still get the vaccine. Policy makers and public health leaders, and the media voices that parrot them, are inexplicably sticking to their original hypothesis that natural immunity is fleeting, even as at least 15 studies show it lasts.
Meanwhile, employers fire workers with natural immunity who won’t get vaccinated. Schools disenroll students who won’t comply.
The CDC did put out
a study on natural immunity last month, forcefully concluding that vaccinated immunity was 2.3 times better than natural immunity. The CDC used these results to justify telling those with natural immunity to get vaccinated.
But the rate of infection in each group was less than 0.01%, meaning infections were exceedingly rare in the short two-month time period the agency chose to study. This is odd, given there are more than a year of data available. Moreover, despite having data on all 50 states, the CDC only reported data from Kentucky. Was Kentucky the only state that produced the desired result? Why else exclude the same data from the other 49 states?
Some public health officials are afraid to acknowledge natural immunity because they fear some will choose infection over vaccination. But leaders can encourage all Americans who aren’t immune to get vaccinated and be transparent with the data at the same time.
The CDC shouldn’t fish for data to support outdated hypotheses. Heeding the robust Israeli data on natural immunity could help restore the agency’s credibility and even help vaccination efforts.
Israel also contributed a brilliant study on vaccinating children. Researchers found that one dose of the Pfizer vaccine, instead of the normal two, was 100% effective in children ages 12 to 15. Such a finding could have significant implications for achieving broad immunity in adolescents while reducing the risk of heart complications, which have been
clustered around the second dose.
These are the studies U.S. public health agencies should be doing but aren’t. By any metric, the CDC has failed in its primary task of preparing the country for a pandemic and telling us how to reduce harm from the novel Covid pathogen.
