Facebook group with 490,000 members spreads vaccine misinformation as measles returns
A Facebook group called Crunchy Moms, with more than 490,000 members, is circulating false claims about vaccines and measles as the disease returns. The claims may deter parents from vaccinating children, while Meta’s systems have also recommended the group to some users.
The article describes a parent seeking advice during a measles outbreak in Pennsylvania and receiving claims that measles cannot kill and that vaccines are harmful. The state reported six measles-associated deaths this year, including two babies in Lancaster County; health officials say the MMR vaccine is safe and the best protection against measles. A Guardian journalist reported more than 50 posts and comments that appeared to breach Meta’s standards, but Facebook took no action on them. Meta said its policies and enforcement had not changed since 2023 and that people may discuss personal experiences and scientific research.
In short
- Crunchy Moms has more than 490,000 members.
- A journalist’s reports of over 50 posts prompted no action.
- Meta says its health misinformation policies have not changed since 2023.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Meta’s approach can be defended on the grounds that people should be able to discuss personal medical experiences and scientific research, and that moderating health claims risks suppressing legitimate debate or making mistakes about context. The company may also argue that its existing policies strike a balance between addressing harmful misinformation and allowing users to exchange views.
The case against
Critics can argue that leaving demonstrably false claims about vaccines and measles unaddressed, while recommending a group of this size, can amplify misinformation and deter parents from evidence-based care. They may say that platforms with broad reach have a responsibility to enforce health policies consistently, especially when children could face preventable risks.
