In Pennsylvania, measles — a disease once rendered nearly invisible by decades of vaccination — has returned with enough force to claim infant lives and summon the machinery of public health response.

Even as some resist, others are being moved by grief and witness to reconsider long-held skepticism, suggesting that the most persuasive public health arguments are sometimes not data, but loss.
