Following significant setbacks due to the COVID-19 pandemic, childhood immunization rates in the world's least affluent nations have begun to climb. Preliminary data from Gavi, the Vaccine Alliance, reveals encouraging progress in essential vaccine coverage.

In 2022, approximately 80% of children in Gavi-supported countries received the crucial diphtheria, tetanus, and pertussis (DTP3) vaccine. This represents a positive shift from the 78% coverage in 2020 and 77% in 2021, though still slightly below the pre-pandemic level of 82%.

While the pandemic's impact on routine childhood immunizations has been described as a substantial setback, this recent data from 57 of the world's poorest countries, supported by Gavi, suggests a hopeful trend of recovery. This initial rebound is seen as a critical first step in addressing the immunization gap created by the pandemic.

The World Health Organization (WHO) emphasizes the urgency of ensuring all children receive essential vaccinations. Wider coverage estimates are expected from the WHO and UNICEF in the coming month. The DTP3 vaccine coverage serves as an important indicator for broader routine immunization rates, including protection against measles and other serious diseases.

This positive development was announced during Gavi's strategic meeting in Madrid, where the organization also celebrated a milestone: reaching over one billion children with vaccinations since its inception in 2000. Supported by various governments and philanthropic organizations, Gavi plays a vital role in facilitating vaccination programs in lower-income nations.
