Ed Pilkington and Jessica Glenza, The Guardian; Facebook under pressure to halt rise of anti-vaccination groups

"Dr Noni MacDonald, a professor of pediatrics at Dalhousie University in Halifax, Nova Scotia, Canada, who has worked as an expert adviser to the WHO on immunization, questioned why Facebook was unrestrained by the stringent controls against misinformation put on drug companies. “We don’t let big pharma or big food or big radio companies do this, so why should we let this happen in this venue?”

She added: “When a drug company puts a drug up in the formal media, they can’t tell you something false or they will be sued. So why is this different? Why is this allowed?”"
