MOSCOW (Reuters) - Russia’s Sputnik V vaccine is 92% effective at protecting people from COVID-19 according to interim trial results, the country’s sovereign wealth fund said on Wednesday, as Moscow rushes to keep pace with Western drugmakers in the race for a shot.

Russia's results are only the second from a late-stage human trial, following on swiftly from data released on Monday by Pfizer Inc PFE.N and BioNTech BNTX.O, which said their shot was also more than 90% effective.

While experts said the Russian data was encouraging and reinforced the idea the pandemic could be halted by vaccines, they warned that the results were only based on a small number of trial volunteers who had contracted COVID-19.

The analysis was conducted after 20 participants developed the virus and examined how many had received the vaccine versus a placebo. That is significantly lower than the 94 infections in the trial of the vaccine being developed by Pfizer and BioNTech.

“I assume there was political pressure after the press release from Pfizer and BioNTech earlier in the week to now draw level with their own data,” said Bodo Plachter, deputy director of the Institute of Virology at the Mainz University. “What is missing for now is an analysis of statistical significance.” ...

The Russian Direct Investment Fund (RDIF), which has been backing Sputnik V’s development, said the Russian trial would continue for six months. ../
