Facebook and YouTube have both removed videos from their platforms featuring Brazil President Jair Bolsonaro, in which the leader makes a false claim that COVID-19 vaccines are linked to developing AIDS.

Both sites said the video violated their policies.

“We removed a video from Jair Bolsonaro’s channel for violating our medical disinformation policy regarding COVID-19 for alleging that vaccines don’t reduce the risk of contracting the disease and that they cause other infectious diseases, and that they cause other infectious diseases,” YouTube said in a statement.

Last month, YouTube moved to remove vaccine misinformation of all kinds from its platform, and has removed more than 1 million videos related to COVID-19 vaccine misinformation since the pandemic began.

Earlier this year, YouTube removed videos from Bolsonaro’s official channel where he recommended using hydroxychloroquine and ivermectin against COVID-19, two drugs that are proven to be ineffective in the treatment of the disease.
