Russia's Sputnik V vaccine, Pfizer, and Moderna induce better than natural immunity from mild COVID

Researchers from Skoltech, two Russian Academy of Sciences institutes, and U.S. biotech companies VirIntel and Argentys Informatics have investigated the effect of coronavirus immunization with three popular vaccines: Moderna, Pfizer, and the Russian Sputnik V. The team found that complete vaccination—that is, getting both shots—on average resulted in a similar and sufficiently high immune response regardless of which of the three vaccines was used. The effect was also comparable to that after recovering from a severe or moderate, but not mild, COVID-19 infection. The findings are reported in a study released as a preprint on medRxiv.
