Tashkent, Uzbekistan (UzDaily.com) -- American scientists believe that vaccination after recovery from COVID-19 allows people to get a "superhuman" immune response that better protects against new strains of infection.

It is noted that two doses of the Pfizer or Moderna vaccine, after an infection, provoke the body to produce a huge amount of "flexible" antibodies, which were effective against 6 mutations of the coronavirus, including the delta and beta variants.

"Flexible" antibodies were also able to cope with a mutation specially created in the laboratory and combining several strains at once. The immunity of only those who had been ill or only vaccinated did not cope with this infection.
