In late December, Twitter announced updates aimed to help stop the spread of false information related to the COVID-19 vaccine. As well as removing harmfully false Tweets that make unsubstantiated claims, Twitter has begun labeling Tweets that might have misleading information about the vaccine.

Both humans and technology review Tweets to check for false claims. And Twitter is working in consultation with numerous health authorities to enforce the policy.

Twitter says this update might go further in 2021, with a warning placed on Tweets that are advancing rumors or falsehoods.
