Mailchimp will no longer serve email newsletters and sites that contain anti-vaccination content.
It has removed several anti-vaccination activists from its platform, NBC News reports.
It adds: “Spreading misinformation about the safety and efficacy of vaccines poses a serious threat to public health and causes real-world harm. We cannot allow these individuals and groups to use our Marketing Platform to spread harmful messages and expand their audiences.”
The firm says it trusts “the world’s leading health authorities, like the CDC, WHO, and the AAP," and will "follow their guidance when assessing this type of misuse of our platform.”
