"In the first and third groups there are antibodies to antigen A, which bears little resemblance to the coronavirus antigen," the doctor explained in an interview with Lente.ru.
Thus, people with the second and fourth blood groups are more susceptible to the risk of infection with coronavirus, and with the first and third - vice versa.
According to Baranova, when a person with these antigens meets a new coronavirus infection, his antibodies can affect the virus and muffle its symptoms.
“The likelihood of not getting sick or transferring an infection is easy for the owners of the first and third blood groups is only ten percent lower,” she explained.
Earlier, virologist Anatoly Altstein, in an interview with the NSN, said that next year could be the final year for a pandemic: when all countries finally get access to vaccines, everything will depend only on the behavior of the population.
