Researchers Review COVID Database, Discover a Lot When They Exclude Vaccinated People

A new study showcases the power of natural immunity to fight the worst effects of the coronavirus.

The researchers, who reported their results last week in New England Journal of Medicine, examined 353,326 COVID-19 patients in the Arabian Peninsula nation of Qatar who were infected anywhere between February 28, 2020 and April 28, 2021.

The study excluded approximately 87,500 people who had been vaccinated during the study period.

Of the rest of the group studied, only 1,304 contracted COVID-19 again, with nobody need intensive care treatment for this disease, officially known as SARS-CoV-2.

Researchers from the Qatar National Research Group on COVID-19 Epidemiology said: “In previous studies, we evaluated the effect of previous natural infection on its ability to protect against re-infection with SARS-CoV-2 is 85% or higher.

“Accordingly, for a person who has had a primary infection, the risk of severe reinfection is only approximately 1% compared with the risk of a previously uninfected person having a severe primary infection.”

The researchers note that the time of natural immunity needs to be better understood.

Is the Biden administration really following the science of COVID-19?

“It is necessary to determine whether protection against severe disease upon reinfection lasts for longer periods, similar to immunity developed against seasonal ‘common cold’ coronaviruses. other, conferring short-term immunity against mild reinfection but longer-lasting immunity against more severe disease with reinfection,” the study said.

If this is the case for SARS-CoV-2, the virus (or at least the variants studied so far) could adopt a more benign form of infection when it becomes infected, the study said. become an epidemic.

The study noted that people infected once has “a 90% lower rate of hospitalization or death than primary infection.”

“Four re-infections were severe enough to result in acute care hospitalization. None of the cases resulted in hospitalization in the ICU and none resulted in death,” the study reported.

“Reinfections are rare and generally mild, probably because the immune system is protected after primary infection.”

“When you only have 1,300 of those reinfections and four with severe disease, that’s pretty remarkable,” said John Alcorn, an immunologist and professor of pediatrics at the University of Pittsburgh. . CNN.

Alcorn was not part of the research team.

According to CNN, one potential weakness in the study: It is limited to Qatari nationals and may not be replicated globally.
