Sputnik V Associated With Higher Antibody Levels Against Omicron Than Pfizer, Study Shows: Reuters

According to a small preliminary laboratory study, omicron-neutralizing antibodies in people vaccinated with Russia's Sputnik V vaccine did not decline as much as of those after Pfizer Inc PFE COVID-19 shots.

• The joint Russian-Italian study was funded by the Russian Direct Investment Fund, which markets Sputnik V abroad.
• The study compared the blood serum of people who had received the different vaccines taken three to six months after the second dose of a vaccine, Reuters reported.
• Data showed that the levels of antibodies in recipients of two doses of Sputnik V (n=51) were more resistant to omicron than in those vaccinated with Pfizer (n=17).
• The preliminary study that will seek certification by peer review showed that omicron-specific neutralizing antibodies were detected in the blood serum of 74.2% of the people vaccinated with Sputnik and 56.9% of those immunized with Pfizer / BioNTech SE BNTX.

• An earlier preliminary study by the Gamaleya Institute, the developer of Sputnik V, showed that a booster shot of Sputnik Light vaccine provided a stronger antibody response against omicron than the two-dose Sputnik V vaccine alone.
• Price Action: PFE stock is up 0.10% at $53.60, BNTX stock is down 0.55% at $160.78 during the market session on the last check Thursday.
