The popular video-sharing site YouTube has deleted more than 30,000 videos that contained misinformation about COVID-19 vaccinations since October, according to the company's spokesperson Thursday.

Axar.az reports that the videos included claims about the vaccinations "that contradict local health authorities or the World Health Organization," said Elena Hernandez in a statement carried by multiple outlets.

"Overall, since February 2020, we have removed over 800,000 videos related to dangerous or misleading coronavirus information," she said.

Last October, the company said it would have the right policies in place to remove misinformation related to a COVID-19 vaccine from the platform and vowed to delete any videos in contraction with local health authorities or the World Health Organization.

Facebook and Twitter have also taken similar actions to prevent misleading information about the COVID-19 vaccinations.

COVID-19 vaccines are effective at preventing COVID-19 disease, especially severe illness and death, but some anti-vaccine activists undermine vaccination, claiming the jabs are deadly.

More than 325.5 million vaccine doses have been administered worldwide, according to data compiled by the Our World in Data project at the University of Oxford.
