Dr. Martin Kulldorf has worked on vaccine epidemiology for nearly twenty years, since joining the Harvard faculty, and is among many epidemiologists who have quickly pointed out the CDC study’s fatal flaws. A Harvard epidemiologist and co-author of the Great Barrington Declaration, has highlighted the severe failings of a Centers for Disease Control study which tried to show that natural immunity for COVID-19 was not as effective as the experimental injections. Amid more than 100 studies showing the superiority of natural COVID-19 immunity over vaccine-produced immunity, the Centers for Disease Control (CDC) released the results this week of a study claiming to show the opposite. But Dr. Martin Kulldorf, who has worked on vaccine epidemiology since joining the Harvard faculty nearly two decades ago, is among many epidemiologists who have quickly pointed out the CDC study’s fatal flaws. In an article for the Brownstone Institute, he compared the CDC research with an Israeli study that found people vaccinated for COVID-19 are 27 times more likely to have a symptomatic COVID infection than those previously infected by the virus. The Israeli study further found that the vaccinated were nine times more likely to be hospitalized for COVID than those with natural immunity. Meanwhile, the CDC study claims that the COVID recovered are five times more likely to be hospitalized for COVID than the vaccinated. Kulldorf, noting both studies cannot be right, said he has never “never before seen such a large discrepancy between studies that are supposed to answer the same question.” Kulldorff is an epidemiologist, biostatistician and professor of Medicine at Harvard Medical School. He is the co-author, along with Dr. Jay Bhattacharya of Stanford and Dr. Sunetra Gupta of Oxford, of the Great Barrington Declaration, advocating a public policy of “focused protection” on the vulnerable while letting others go about their business. More than 860,000 people have signed the declaration, including 14,981 medical and public health scientists, and 44,167 medical practitioners. As the federal and local governments double down on vaccine mandates, a new study by the Yale School of Public Health offers the latest evidence that the immunity acquired by COVID-19 infection is superior to the immunity from vaccination. A total of 102 studies with the same conclusion has been compiled by Dr. Paul Elias Alexander and several other prominent colleagues. Defending their paper, Israeli researchers said their analysis “demonstrated that natural immunity affords longer lasting and stronger protection against infection, symptomatic disease and hospitalization due to the delta variant.”
