BUENOS AIRES, January 25. /TASS/. Venezuelan medics have not registered serious complications in volunteers who participated in clinical trials of the Russian Sputnik V vaccine against the coronavirus, Venezuelan doctor Alexis Garcia Pinera who directs the research of the vaccine in the Latin American republic reported on Sunday.

"The first dose was received by over 200 volunteers, both components - by 40. As for complications, which is the most important thing during trials, only light side effects were detected: headache, flu-like condition or pain at the site of injection," he said during a speech which was aired on Venezuelan President Nicolas Maduro’s Twitter.

The doctor also noted that in Venezuela "not a single case of serious complications or of death of a volunteer was registered." "Our results coincide with what one can find in research publications and with the vaccination results in Russia and Argentina," he added.
