## Summary

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.
