Falling vacination rates endanger children with compromised immune systems

Zoé Paul, 6, looks out the front door of her Windham home. For Zoé, who was born with a rare birth defect that required a liver transplant at age 2 and has a weakened immune system, vaccines are a life-or-death matter. Maine's vaccination rates for students entering kindergarten worsened yet again, making the return of preventable diseases like measles, pertussis, chicken pox more likely, and puts children like Zoé at risk.
