Italy has passed a law that will require parents to vaccinate their children before pre-school. Those who refuse may be fined.
Children up to age six will need to be vaccinated against several diseases, including measles, chicken pox and meningitis.
The country’s health institute recorded 2,395 cases of measles so far this year, a big increase from 840 cases in all of 2016, and 250 in 2015.
The high numbers prompted other countries to warn citizens about potential exposure to measles while visiting Italy.
