The outbreak of COVID-19 triggered the worst health crisis of the 21st century, and some of its serious consequences are still being felt five years later. One of these is the significant drop in routine vaccination rates—that is, the vaccines included in pediatric schedules to protect newborns from preventable diseases, such as diphtheria, whooping cough, polio, and measles. According to data published Tuesday by the World Health Organization (WHO) and UNICEF, global childhood immunization coverage has improved slightly compared to 2023, when they warned that had stagnated, but last year's data is still below that of 2019. Thus, health authorities warn that the improvement is not enough to make progress towards the goals of the 2030 Vaccination Agenda, and they call on countries to make efforts to reduce the number of children who have not received vaccinations. In 2024, there were still 1.4 million more unvaccinated children than in 2019, and approximately another 4 million are missing to reach the proposed target within five years. Furthermore, the poorest countries are those with the least signs of recovery: they are the furthest from recovering pre-pandemic vaccination coverage and those experiencing the fastest population growth.
