Before Alec Mkwamba joined the Ministry of Health in São Tomé and Príncipe, immunization records existed only on paper. Lost vaccine cards meant missed doses, leaving many children unprotected. As an Epidemiologist and Project Manager with the United Nations Development Programme (UNDP), Alec led efforts to transition the health information system to digital platforms, certifying that the children’s vaccination histories were accessible no matter where they received care.

In northeast Nigeria, where conflict has displaced thousands, UN Volunteer Mary Mahdi Bumba works with the United Nations Population Fund (UNFPA) as a Digital Literacy Facilitator. Mary’s journey began by addressing the digital gender gap, equipping girls in internally displaced persons (IDP) camps and schools with essential tech skills. As her initiative grew, boys and adults joined in, learning practical skills like social media marketing and graphic design. These tools go beyond the classroom.
