Denmark routinely vaccinates all kids against just 10 diseases.

In the U.S., it's 16 diseases.

Dr. Sean O'Leary with the American Academy of Pediatrics says the two countries are very different.

Denmark also has free universal health care.

Families get about a year of paid parental leave so they can stay home with their babies, so they potentially aren't exposed to as many diseases.

And if a child gets hospitalized, their health system absorbs that cost.

Meanwhile, in the U.S., many people struggle with access to health care and paid leave.
