The study showed the high efficiency of “Sputnik V” against the delta strain of coronavirus
Spanish scientists conducted a study of the plasma of people previously vaccinated against COVID-19 and recovered from this virus. They revealed the high efficiency of the Russian Sputnik V vaccine against the delta strain of coronavirus in comparison with the drugs AstraZeneca and Sinopharm, RIA Novosti writes with reference to the newspaper La Nacion .
Specialists from the National University of Cordoba studied 309 plasma samples from patients who had undergone coronavirus and received two doses of Sputnik V vaccines, AstraZeneca (England-Sweden) and Sinopharm (China). They noted that the highest titers of antibodies against the delta strain were in those who were vaccinated with the Russian drug and had had COVID-19 earlier.
In second place in terms of high titers were those who received two doses of Sputnik V, but did not have a coronavirus infection. In third place in terms of protection were those who received two Sinopharm vaccinations and were not sick with COVID-19.
A delta strain of coronavirus has emerged in India. It is twice as infectious as the original virus. The WHO expressed concern about its spread around the world.
We will remind, earlier the head of the Center. Gamaleya of the Russian Ministry of Health Alexander Gintsburg said that the creators of the Sputnik V vaccine had modernized the drug so that it could fight against the delta strain. And the head of Rospotrebnadzor, Anna Popova, said that in Russia, about 95% of cases of COVID-19 infection are attributed to this strain.
