Even under normal circumstances, parents in many parts of the world struggle to get their children the vaccinations they need to protect against deadly infections such as measles, whooping cough, and diarrheal diseases. But as the coronavirus pandemic sweeps across the world, national governments and nongovernmental organizations alike are struggling to contain its spread while preserving essential health care services like routine immunization. Unlike COVID-19, measles can be prevented with a vaccine—but only if children receive it. The Measles and Rubella Initiative estimates that more than 117 million children in 37 countries will miss out on measles vaccines because mass-vaccination campaigns and other immunization services will be suspended due to the pandemic. How do you make sure kids get the vaccines they need while also protecting them from COVID-19? In this video, Doctors Without Borders/Médecins Sans Frontières (MSF) vaccines policy advisor Kate Elder reflects on the dilemma that’s keeping her up at night.
