The crowdfunding platform announced it was carrying out a “thorough review” following reports that one campaigner had gathered nearly $80,000 (£60,000) in donations.
Larry Cook, who promoted his fundraising efforts using Facebook adverts, targeted mothers with claims the medical community was covering up baby “slaughter”.
GoFundMe spokesman Bobby Whithorne said: “Campaigns raising money to promote misinformation about vaccines violate GoFundMe’s terms of service and will be removed from the platform.
“We are conducting a thorough review and will remove any campaigns currently on the platform.”
However The Independent has found several campaigns promoting the anti-vaxxer message still running on the site, three weeks after GoFundMe’s decision was reported by The Daily Beast.
