Challenges to Reaching Coverage Goals

Vaccine supply on a global level has greatly improved over the past year and is no longer the critical limiting factor in 2022. However, supply remains an issue at the local level, particularly for low- and lower-middle income countries in Africa, Eastern Mediterranean, and South-East Asia regions.

For many countries, the primary challenge has shifted from lack of supply to capacity to utilize available supply before product expiration. Daily vaccination rates in many countries remain low. Low- and lower-middle-income countries report significant challenges to vaccination, including lack of sufficient cold storage and transport, shortage of health care workers, vaccine misinformation, and competing health priorities.
