Data published by the World Health Organization (WHO) and UNICEF purports that an additional 2.7M children were under or un-vaccinated in 2023 compared to 2019, based on their analysis of immunization trends for 14 diseases.
The number of children who haven't received a single dose of the diphtheria, tetanus and pertussis (DTP) vaccine — a benchmark figure for child immunization — went from 12.8M pre-pandemic to 14.5M in 2023, while 6.5M did not receive their final, third dose of the shot.
