British photographer David Chancellor captures immunization pioneers in South Africa, who helped transform the country’s vaccination program post-apartheid. David’s portrait takes place in a lively children’s crèche in Khayelitsha, near Cape Town, under the gaze of a colourful mosaic of Nelson Mandela. During apartheid, the country’s health system was fragmented and unequal. Dr. Neil Cameron, former Director of Communicable Disease, Outbreaks, & Immunization, calls the post-apartheid period a “magical time” when old barriers came down, and programs were changed so that all children could access life-saving vaccines. Dr. Cameron is joined in the portrait by Dr. Virginia Azevedo and Veronica Isaacs who all played pivotal roles in improving immunization in the 1980s and 90s. Together they look on while Nurse Nosipho gives a young child a vaccine.
