Natural immunity "protection was higher than that conferred after the same time had elapsed since receipt of a second dose of vaccine among previously uninfected persons," concludes the study.
"Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) provides natural immunity against reinfection," the study states at the outset, adding that recent studies have shown "waning of the immunity provided by" the Pfizer shot.
"Therefore, continued disregard for immunity from natural infection is not only contrary to all the published science, it’s an egregious affront to medical ethics," he added.
"Throughout the pandemic, public health experts have ignored and even disparaged immunity after natural infection, exclusively emphasizing immunity from COVID vaccines. Many people have been unethically forced into unemployment from vaccine mandates that did not accommodate immunity from natural infection. Repeated studies have shown that immunity after COVID infection is comparable or even better than immunity after COVID vaccination," Verma said.
A chart showing the different levels of protection and waning efficacy against infection shows that those in the 4 to <8 months "1 dose + recovered" group didn't experience significantly fewer infections than the "recovered, unvaccinated" group in the same time frame.
In addition, the data doesn't show the 4-8 month result for people who took 3 doses.
