The United States and its allies are plotting a "disinformation campaign" to hurt the credibility of Russia's Sputnik V vaccine, Russia's RIA Novosti and TASS news agencies reported on Friday.

According to Russia's special services, such a campaign is being prepared by non-governmental organizations and media in the West, a high-ranking source in the Kremlin was quoted as saying.

The campaign will focus on discrediting the Russian vaccine by fabricating information about its ineffectiveness and even danger to people's lives, the source said.

Russia has registered three COVID-19 vaccines, namely Sputnik V, EpiVacCorona and CoviVac.

As of March 4, more than 2 million people in Russia have received both doses and another 2 million have received the first jab since it started mass vaccination early December.
