A spokesperson for the Kremlin on Tuesday denied allegations from the White House that Russia has been working to discredit western coronavirus vaccines, calling it “absurd.”

Russian intelligence services bear direct responsibility for using these four platforms to spread propaganda and lies, a State department spokesperson said. From the very beginning of the COVID-19 pandemic last year, we have seen Russias disinformation ecosystem develop and spread false narratives around the crisis.
