A Perilous Quest to Save the World’s Children tells the inspiring story of Dr. Maurice R. Hilleman, a man with a singular, unwavering focus — to eliminate the diseases of children. From his poverty-stricken youth on the plains of Montana, he came to prevent pandemic flu, develop the measles-mumps-rubella (MMR) vaccine, and invent the first-ever vaccine against human cancer.
