Experts worry that a bill to suspend compulsory vaccination of children in Italy could spread the anti-vaxx movement across borders, posing a serious global health threat. Pushed by Italy's populist government, the bill will become law if approved by the lower house of its parliament.

Why it matters: Vaccinations have helped to eradicate a dozen major childhood diseases and are praised as a key advance of the 20th century. But the anti-establishment wave in Europe and the U.S., plus the ability of social media to spread any opinion, have put new impetus behind the opposition to mandatory inoculation.
