The CDC recently released a study contending that COVID artificial immunity is superior to natural immunity, which on its face obviously goes against common sense and science. Current studies in the Cantor lab have begun to define regulatory T cell lineages that inhibit the development of autoimmune disease and may regulate anti-viral and anti-tumor immunity. In today’s MMWR, a study of COVID-19 infections in Kentucky among people who were previously infected with SAR-CoV-2 shows that unvaccinated individuals are more than twice as likely to be reinfected with COVID-19 than those who were fully vaccinated after initially contracting the virus. Photos courtesy of Michael N. Starnbach, Ph.D., Harvard Medical School Natural immunity comes from battling and defeating an actual infection, then having your immune system primed for the rest of your life to fight it off if it ever shows up again. The new study runs counter to an Israeli analysis, made public in August, that suggested the opposite, with natural immunity seemingly offering greater protection than vaccination. New research found that natural immunity offers exponentially more protection than COVID-19 vaccines. “That natural immunity, it does appear to be stronger than the immunity that the vaccines are able to elicit in patients who have never had COVID,” Dr. Webb adds. Additionally, the immunity wanes over time. The study immediately added that getting natural immunity entails contracting COVID-19, and “a natural infection can also kill you.”. Some epidemiologists describe a government study comparing vaccine and natural immunity as potentially biased. 12.04.2022.

The study’s results show the overwhelming majority of subjects received natural immunity from prior infection, regardless of whether the case was ‘severe’ or ‘mild.’ The researchers also sought to assess if natural immunity to certain variants of concern can be expected to protect against future variants. Dr. William Hanage, an associate professor of epidemiology at Harvard’s T.H. “This study indicates that it’s not simply the presence or absence of antibodies that matter; rather, the amount and type of antibodies that may play a defining role in the development of a protective immune response,” said study senior investigator Galit Alter, professor of medicine at HMS and core member of the Ragon Institute of MGH, MIT and Harvard.

A study from the CDC in September 2021 showed that roughly one-third of those with COVID-19 cases in the study had no apparent natural immunity. In an effort to predict future evolutionary maneuvers of SARS-CoV-2, a research team led by investigators at Harvard Medical School has identified several likely mutations that would allow the virus to evade immune defenses, including natural immunity acquired through infection or from vaccination, as well as antibody-based treatments. Background: Protection afforded from prior disease among patients with coronavirus disease 2019 (COVID-19) infection is unknown. A recent letter in the New England Journal of Medicine illustrates the point. At a Glance. More than 15 studies have demonstrated the power of immunity acquired by previously having the virus.

Revised article below: An Israeli case study conducted by researchers at top Ivy League universities appeared to confirm that natural immunity was 27 times more effective than vaccines at preventing symptomatic transmission of the deadly coronavirus. National Institutes of Health Director Francis Collins “intentionally misrepresented” the conclusions of an August study on people with natural immunity from COVID-19 in violation of his agency’s scientific integrity policy, a watchdog group alleged in a complaint Wednesday. Harvard Medical School professor Martin Kulldorff argues that new research cofirming that natural immunity offers exponentially more protection than vaccines means vaccine passports are both unscientific and discriminatory. Yet public health leadership says everyone needs the vaccine. Herd immunity for the coronavirus may be "wishful thinking," according to Dr. Clay Ackerly. “Vaccine-induced immunity is way better than infection and recovery, what some call weirdly ‘natural immunity,’” Baylor College of Medicine infectious disease expert Dr. Peter J.

Largest real-world study of COVID-19 vaccine safety published. That is true. Contrast that with immunity from infection, which has been shown to be impervious in every study. A healthy immune system can defeat invading pathogens as shown above, where two bacteria that cause gonorrhea are no match for the large phagocyte, called a neutrophil, that engulfs and kills them (see arrows). shaffer mf, enders jf, wu cj. The study looked at data from the VISION Network that showed among adults hospitalized with symptoms similar to COVID-19, unvaccinated people with prior infection within 3-6 months were 5.49 times more likely to have laboratory-confirmed COVID-19 than those who were fully vaccinated within 3-6 months with mRNA (Pfizer or Moderna) COVID-19 vaccines. “Conclusions This study demonstrated that natural immunity confers longer lasting and stronger protection against infection, symptomatic disease and hospitalization caused by the Delta variant of SARS-CoV-2, compared to the BNT162b2 two-dose vaccine-induced immunity.
