ARE CORONA VIRUS VACCINES EFFECTIVE AGAINST DELTA MUTANTS?
According to results from some laboratory studies, the Delta variant shows greater resistance to vaccines than other variants of SARS-Cov-2. The results of a study conducted in England were published in the journal “The Lancet” in early June. In the aforementioned study, it was determined that after two doses of Pfizer/Biontech vaccine administered to the Delta variant, six times lower antibodies developed in the body compared to the original virus type. This rate of regression was determined as 2.6 factors in the Alpha variant, which was first detected in England, and 4.9 factors in the Beta variant, which was first seen in South Africa.
