Although numbers have decreased since the peak of the pandemic, when 24.4 million children missed out on the vaccines in 2021, they are still high compared to before Covid-19 began. In 2019, 18.4 million children were not fully protected.

According to the two UN agencies, the number of children without even a first dose of the diphtheria, tetanus and whooping cough vaccinations went down in all regions of the world.

The WHO and Unicef have also warned that measles vaccinations continue to decline in low-income countries and outbreaks of the disease are already on the rise.
