According to health reports, large outbreaks of diseases that primarily kill children are spreading around the world, a grim legacy of disruptions to health systems during the Covid-19 pandemic that have left more than 60 million children without a single dose of standard childhood vaccines.
Nigeria is currently facing the largest diphtheria outbreak in its history, with more than 17,000 suspected cases and nearly 600 deaths so far.
Twelve countries, from Afghanistan to Zimbabwe, are reporting circulating polio virus.
Many of the children who missed their shots have now aged out of routine immunization programs. So-called “zero-dose children” account for nearly half of all child deaths from vaccine-preventable illnesses, according to Gavi, the organization that helps fund vaccination in low- and middle-income countries.
An additional 85 million children are under-immunized as a result of the pandemic — that is, they received only part of the standard course of several shots required to be fully protected from a particular disease.
