Olga DobrovidovaRussia’s Sputnik V vaccine is holding up well against the Delta variant, a paper posted yesterday on the preprint server medRxiv shows.
The study of nearly 14,000 people showed the two-dose vaccine reduces the risk of hospitalization with COVID-19 by 81% and helped prevent severe lung injury.Surges of COVID-19 in many countries and an increasing number of “breakthrough” cases in vaccinated people have raised concerns that vaccines don’t protect as well against Delta as against earlier strains, or that vaccines’ protection may be short-lived.
