It’s only censorship if the government does it. However, I think there’s a grain of truth to the idea that vaccinations are harmful. The veterinary profession has severely cut back on its recommended vaccination protocol after years of associating such ill effects as auto-immune disease and certain cancers with over-vaccination. They have done this to their own cost, in terms of actual revenue.
It is censorship when someone censors it. Not sure why people want to deny that unless government does it.
