Can "The Big Catch Up" Boost Childhood Vaccinations Worldwide?

Before COVID more and more children around the world were receiving their routine vaccinations on time and in full. But COVID severely interrupted that progress. Now, we are seeing lagging indicators of interrupted childhood vaccinations in the form of outbreaks of vaccine preventable diseases like measles and diphtheria.  To reverse this trend a number of global health entities have joined forces for what they call "The Big Catch-up" to boost vaccination among children following declines driven by the COVID-19 pandemic. joining me to discuss trends in routine childhood vaccinations around the world, the impact of COVID 19 on those trends and what can be done to restore progress is Dr. Ephrem Lemango, associate director of immunization at UNICEF headquarters in New York.
