  International public health policies increasingly favor mandatory
immunization. If its short-term effects on vaccine coverage are well
documented, there has been little consideration to its effects on public
attitudes towards vaccines. In this paper, we examine Google searches related
to vaccines in five countries (Australia, France, Germany, Italy, Serbia) and
two American states (California) which experienced at least one vaccine mandate
extension in the past decade. We found that the effects of a new mandate
implementation heavily depends on the context in each specific country or
state. We also observed that there is little indication that the passing of new
or extended mandates attenuated public doubt towards vaccines.
