The Vaccine Trust Team had the pleasure of joining Gates Foundation stakeholders and teams from around the world as they discussed their work to reach zero-dose families. The Zero Dose Learning Agenda (ZDLA) brings together partners who are actively experimenting with different ways of reaching those who are currently missed or under-vaccinated. Working across a diverse range of contexts, the ZDLA teams have done deep research and designed interventions with and for communities – ranging from outreach to parents, to HCW training – which are now being implemented.
