The endless variants of the COVID-19 virus seem to have finally encountered a "nemesis". According to a foreign media report on September 7, a series of studies in the past few months have found that a part of the population has acquired "superhuman" mixed immunity against the COVID-19 virus, which can resist various future COVID-19 viruses. The variant can even resist pan-coronavirus similar to SARS.
Someone already has "superhuman" immunity to COVID-19
"Superhuman" hybrid immunity is born
Mixed-exposure populations can resist various COVID-19 variants
How does this mixed immunity come from? According to reports, those people were first infected with the COVID-19 virus in 2020, then vaccinated, and after a "mixed" double exposure to the virus, they eventually gained "superhuman" immunity.
Studies have found that people who have undergone this "mixed" exposure can produce high levels of antibodies in their bodies. At the same time, their antibodies are also very flexible and can withstand various global COVID- including Delta. 19 variants, coronaviruses in animals, and even COVID-19 variants used in laboratory tests. Therefore, scientists call it "superhuman immunity".
Paul Viñas, a virologist at Rockefeller University in the United States, believes: "You can reasonably speculate that people will be able to resist most or all of the COVID-19 variants that we may face in the foreseeable future. "
Paul Viñas and his colleagues compared antibodies in 15 people who had been exposed to mixed exposures and those who were only vaccinated or only naturally infected. It was found that the antibodies in the human body after the mixed exposure can strongly neutralize the six COVID-19 variants in the test, including delta and beta; it can also resist several viruses related to the COVID-19 virus. Such as SARS.

The virologist Theodora Hatziioannou who participated in several of these studies pointed out: "The antibodies in these people's blood can even neutralize SARS (SARS-CoV-1). That's 20. The one that appeared a year ago is very different from the COVID-19 virus (SARS-CoV-2)."
Their antibodies can even deal with coronaviruses in animals, including one in bats and two in pangolins. Therefore, Viñas believes: "They even have a certain degree of protection against SARS-like viruses that have not yet been able to infect humans."
These antibodies also showed high resistance to the COVID-19 virus variants specially made in the laboratory for testing. This variant contains 20 variants in order to prevent antibodies from binding to it. Antibodies in people who have only been vaccinated or have only been infected are "useless" in the face of it, but antibodies with "mixed immunity" can neutralize them.

Pan-coronavirus vaccine is being studied
Will work for all future variants
Scientists explained that the antibodies in the human body evolved after being naturally infected with the COVID-19 virus, becoming not only more potential, but also a wider range of resistant variants. But the immunity gained by natural infection is different from the immunity gained by vaccination. Previous studies have found that the human body’s natural immunity will be maintained for 7 to 8 months. After about a year, it can only save part of the “memory” of the virus, making it more susceptible to mutations. But if the patient is vaccinated after recovering from COVID-19, the "memory" of the immune system will be strengthened. Moreover, the "new infections" caused by this vaccine will make the immune system treat it as a serious threat, thus mobilizing more resources to initiate a stronger defense.
Paul Viñas pointed out: "Based on all these findings, it seems that the human immune system will eventually defeat this virus."
"In general, the mixed immunity against the COVID-19 virus looks very promising." Immunologist Shane Crotty (Shane Crotty) also commented in a review in Science magazine.
Of course, there are still many questions to be answered by further research: If you are vaccinated first and then infected with the COVID-19 virus, do you still have the same mixed immunity? If a person has not been naturally infected but has been vaccinated with a booster shot, can he gain mixed immunity? In addition, the current research sample size is relatively small, can everyone get mixed immunity?
In addition, many studies are now trying to find a pan-coronavirus vaccine that will work for all future variants. These studies show that mankind now has a way out.
