Going Viral: Vaccines, Free Speech, and the Harm Principle

This paper analyzes the case of public anti-vaccine campaigns and examines whether there may be a normative case for placing limitations on public speech of this type on harm principle grounds. It suggests that there is such a case; outlines a framework for when this case applies; and considers seven objections to the case for limitation. While not definitive, the case that some limitation should be placed on empirically false and harmful speech is stronger than it at first appears.
