“This is important work,” comments publication of scientists biologist Ancha Baranova. “It follows from this that a long “Covid tail” is more likely to grow in those who, even before meeting SARS-CoV-2, had met its little brother named HCoV-OC43, which has been roaming human populations since at least 1963.”
Those patients who already had antibodies to this virus Having become infected with Covid, they could not “raise” a new type of antibodies to the coronavirus spike to the required height and turned out to be more prone to delayed covid symptoms for a long time, that is, to “long” covid.
“This was “antigenic sin” – explains the expert. “The bodies of those who recovered from OC43 chose to neutralize SARS-CoV-2 with everything they already had, instead of making new, specific antibody weapons, and as a result were unable to respond to the Covid invasion properly.”
