Vaccination strategies to identify and reach zero-dose and under-immunized children in crisis-affected states in Sudan: a qualitative study.

Background: Globally, 21 million children were un- or under-vaccinated with Diphtheria-Tetanus-Pertussis (DTP)-containing vaccines in 2023. Around 20% of zero-dose children, those who had not received any DTP doses, live in conflict-affected settings in low and middle-income countries. There is insufficient evidence on vaccination interventions to identify and reach zero-dose children in these settings.

Perceived Vaccine Availability and the Uptake of Measles Vaccine in Sudan: The Mediating Role of Vaccination Hesitancy.

This study aimed to evaluate whether measles vaccine uptake can be predicted directly or indirectly by parental perceptions about the availability of measles vaccine services with parental hesitancy towards the measles vaccine as a potential mediator. This was a community-based cross-sectional study conducted at Omdurman locality in Khartoum state, Sudan in February 2019. The study population included parents/guardians having at least one child aged 2-3 years old.
