On social networks, doubt about the effectiveness of covid-19 vaccines continues to be expressed and circulate.

People who are visibly affiliated with the conspiracy theory movement QAnon manage to sow doubt without even breaking the community rules. It’s a grey area for Facebook between freedom of expression and propagation of false information that makes moderation more difficult than expected.
