"But the pandemic has put those gains at risk. The avoidable suffering and death caused by children missing out on routine immunizations could be far greater than COVID-19 itself. But it doesn’t have to be that way. Vaccines can be delivered safely even during the pandemic, and we are calling on countries to ensure these essential life-saving programmes continue."
