The global immunization coverage in 2024 was a significant milestone, with 89% of infants globally, nearly 115 million children, receiving at least one dose of the DTP vaccine. This marks a 20 million increase over the target to continue achieving Immunization Agenda 2030 goals. Three doses of the staple shot against diphtheria, tetanus, and whooping cough, known as whooping cough shots, were completed by more than 109 million infants, surpassing the previous year’s 109 million who finished all three doses. However, nearly 20 million infants missed at least one dose of the vaccine, exceeding the global target of 4 million more than needed to stay on track with the Immunization Agenda 2030.
Despite the Establishing Member国 ( singly vaccinated), the vaccine coverage progress recognized by critics, the data reveal that global vaccination challenges persist. A quarter of the world’s infants—those in 26 countries facing fragility, conflict, or humanitarian crises—make up half of all unvaccinated children globally. These children, whose numbers have grown by 166% from 2019 to 2024, are particularly vulnerable to preventable diseases. Moreover, 20% of eligible adolescents globally have received at least one dose of the HPV vaccine, up from just 17% in 2019, reflecting progress in preventing preventable circulating infections.
In contrast, measles coverage improved, though global coverage rates remain far below the 95% needed in every community to prevent outbreaks. Some key vaccine programs include HPV for adolescents and有期徒刑 for高山 mandates for children under 5 in Latin America andTARGET-H2F for life in high-risk countries, but scalability remains uncertain. The article also discusses the potential of innovative vaccine production and accessible delivery to expand this progress, even as global conflicts create barriers for vaccine distribution.
grappling with the potential for further stalls or reversals, the progress reflects the lingering effects of policies and misinformation. O’Brien emphasizes that breaking this glass ceiling will be more difficult and that addressing vaccine-preventable diseases is becoming increasingly challenging. Despite these obstacles, countries are demonstrating progress in scaling up vaccines for key diseases, but challenges remain.
UNICEF Executive Director Cat tess Russell highlights the need for ongoing efforts to address uncovered gaps. “We know there’s still work to be done,” she says, “but we are taking massive, decisive steps forward.” As the world grapples with these challenges, the stakes for vaccine safety and global health are becoming increasingly aligned.
