Late-stage data on an experimental COVID-19 vaccine from Sanofi and GSK has shown the shot confers protection against the Omicron variant of the virus, the companies said on Friday.In a trial involving 13 000 adults, the vaccine demonstrated an efficacy rate of 64.7% against symptomatic COVID-19, and 72% efficacy against infections specifically caused by the Omicron variant.
When used in people who previously had COVID-19, the results were stronger. The vaccine generated an efficacy rate of 75.1% against symptomatic COVID19 and 93.2% in Omicron-confirmed symptomatic cases, the companies said. “Sanofi-GSK’s vaccine is the first candidate to demonstrate efficacy in a placebo-controlled trial in an environment of high Omicron variant circulation,” Sanofi said in a statement.
Sanofi’s Paris-listed shares and GSK’s London-listed shares were both up more than 1% in morning trading.
