Facebook under fire for allowing anti-vaccine doctors grow into 'superstars'

Joe McCarron, from Dungloe, who had refused the vaccine, left hospital after being treated for Covid-19 and later died.

An international group of former and current healthcare professionals promoting anti-vaccine sentiment have reached millions of users on Facebook, despite promises by the platform to tackle disinformation, a report has claimed.

The World Doctors Alliance, which has members across the world, including Ireland's Dolores Cahill, has falsely claimed that Covid-19 is a hoax.
