The Centers for Disease Control and Prevention released a study which claims that the COVID-19 mRNA-vaccines provide better protection against illness than natural immunity, Just the News reported.
“All eligible persons should be vaccinated against COVID-19 as soon as possible, including unvaccinated persons previously infected with SARS-CoV-2,” the CDC study concluded.
The study, which tracked only “7,000 COVID-19–like illness hospitalizations,” found that there “was a 5.5 times higher odds of laboratory-confirmed COVID-19 among previously infected patients than among fully vaccinated patients.”
The study contained major flaws, according to immunologist Hooman Noorchashm, who called it a “piece of propaganda” in a tweet.
Noorchasm found two major problems: the CDC’s study did not include people who have received the Johnson & Johnson shot among the vaccinated, and it may have counted people among the vaccinated who had also developed natural immunity.
I have some ideas why this study purporting to show vaccine immunity is better than NI is flawed but would be really helpful to hear from scientists. @MartinKulldorff @DrJBhattacharya @mahesh_shenai @DrSamPappas @noorchashm @GirardotMarc @NickHudsonCT

The authors admit the second defect: “If SARS-CoV-2 testing occurred outside of network partners’ medical facilities or if vaccinated persons are less likely to seek testing, some positive SARS-CoV-2 test results might have been missed and thus some patients classified as vaccinated and previously uninfected might also have been infected.”
The authors identified “seven limitations” in the study’s conclusions, yet they boldly claimed the need for universal vaccination, including for people with natural immunity.
The CDC study also rejects an earlier and much larger Israeli study, which found that natural immunity is superior to the immunity acquired from an mRNA injection.
The CDC even mentions this study in its “Comparison of Infection- and Vaccine-induced Immune Responses.”
“A systematic review and meta-analysis including data from three vaccine efficacy trials and four observational studies from the US, Israel, and the United Kingdom, found no significant difference in the overall level of protection provided by infection as compared with protection provided by vaccination; this included studies from both prior to and during the period in which Delta was the predominant variant,” according to the CDC website.
