WHO, UNICEF, Gavi, the Vaccine Alliance and the Bill & Melinda Gates Foundation, along with Immunization Agenda 2030 and many other global and national health partners, are today joining forces to call for “The Big Catch-up”, a targeted global effort to boost vaccination among children following declines driven by the COVID-19 pandemic.

This effort aims to reverse the declines in childhood vaccination recorded in over 100 countries since the pandemic, due to overburdened health services, closed clinics, and disrupted imports and exports of vials, syringes and other medical supplies. Meanwhile, communities and families experienced lockdowns, restricting travel and access to services, and financial and human resources were limited along with access to health commodities, due to the emergency response. Ongoing challenges like conflicts, climate crises and vaccine hesitancy also contributed to the decline in coverage rates.
