Protection against reinfection is highest for the ancestral (original) strain of COVID-19 and alpha, beta, and delta variants, remaining at more than 78% after 40 weeks.
Decreased protection for the omicron BA. 1 variant, which fell to 36. 1% in the same period.

For severe illness (hospitalization or death), coverage is maximum in all variants, with an average of 78% or more for ancestral, alpha, beta, delta, and omicron BA. 1 40 weeks after infection.
The coverage point decreased over time for all variants, but dropped to the maximum for the omicron BA. 1 variant.
The study, titled “Coverage of past SARS-CoV-2 infection as opposed to reinfection: a systematic review and meta-analysis,” conducted through an organization of researchers that make up the COVID-19 prediction team.
A previous COVID-19 infection provides at least the same point of coverage as two doses of mRNA vaccines.
Dr. Marc Siegel, a professor of medicine at NYU Langone Medical Center in New York and a medical contributor to Fox News, told Fox News Digital that immunity to a past infection (called herbal immunity) and immunity to vaccines offer significant opposite coverage. to severe illnesses and some coverage (for at least a few months) against the recurrence of the virus.
“That’s why I don’t propose the booster vaccine for at least a few months after infection,” he said.

Dr. Siegel said the most powerful immunity is a mixture of both, known as hybrid immunity; However, I would never recommend that it be deliberately inflamed.

“It’s too unpredictable in terms of the end results of the disease and the spread of COVID,” he said.
The effects of the new study could simply include vaccine requirement policies.

“This location also has vital implications for the design of policies that limit access to or require vaccination of workers,” the study authors wrote.
“This supports the concept that those who have a documented infection should be treated in the same way as those who have been fully vaccinated with high-quality vaccines. “

The researchers analyzed a total of studies in 19 countries.
The studies compared other people who had previously recovered from COVID-19 with those who had not been infected, until September 31, 2022.
When assessing inflamed cases, the researchers took into account the severity of symptoms, variant virus and the time since other people tested positive.
The authors noted in effects that this is the first study to “comprehensively assess the coverage of natural immunity against the COVID-19 variant of reinfection (infection number one and reinfection) and assess the reduction of immunity over time since infection number one. “
As of Feb. 15, the Centers for Disease Control and Prevention reported an average of 259,339 new COVID cases during the week.
He had some limitations.
There were few studies to evaluate, for example, and little knowledge was available beyond 40 weeks.

In addition, the studies built on other strategies for previous infection status, adding the search for antibodies and reviewing the effects of previous COVID-19 testing.
