The coronavirus vaccine that Russia developed is safe and elicited "strong humoral and cellular immune responses" in human trials.
As part of a study published in The Lancet, researchers in Russia detailed their findings based on two trials that involved a total of 76 people between June 18 and Aug. 3.
The vaccine, they wrote, "has a good safety profile and induced strong humoral and cellular immune responses in participants. Further investigation is needed of the effectiveness of this vaccine for prevention of COVID-19."
The two vaccine trials were non-randomized and included male and female volunteers aged 18 to 60.
"All participants produced antibodies to SARS-CoV-2 glycoprotein," they wrote, referencing the virus that causes COVID-19.
Last month, Russia announced it had developed a vaccine for COVID-19, saying one of President Vladimir Putin's daughters had already received it. The news, however, was met with skepticism because the vaccine had not been tested in a phase 3 trial.
Advanced trials are now underway.
