Can vaccinations cause more harm than good?

According to UNICEF, in the first three months of 2019, more than 110,000 measles cases were reported worldwide. That's almost triple the amount from the same period last year. The vaccine to prevent the disease is 97 percent effective. So we asked if vaccinations should be optional or mandatory.
