Noting “a full 84 percent of the world’s one-year-olds are vaccinated against measles,” Orin Levine, director of vaccine delivery at the Bill & Melinda Gates Foundation, writes in the foundation’s “Impatient Optimists” blog that “less than one in five Americans identified the correct level” in a recent Gapminder survey. The survey “provides a wakeup call that too many of us are unaware of the impact our contributions are having in expanding childhood vaccinations, fighting deadly disease and saving lives,” he writes, concluding, “We need to take the responsibility to share what we know so that others see those successes and ironically, their role in them. Without their support we risk successful programs going unsupported because of ignorance or misinformation” (12/14).
