They are very few (read: "none as far as I know it") people jailed in the EU for having said that vaccines were "dangerous / ineffective / a plot by the governement to inject 5G chip / insert theory here" - neither for writing it on social media, nor for telling it on broadcast radio / TV.

However, and sorry for the cliché, there seems to be some places where you can get in jail for calling a "special operation" a cat.
