Thabani is managing director of country programs at GAVI, the global vaccine alliance, where he oversees equitable distribution of vaccines distribution to some 73 to low- and middle-income countries around the world. Thabani, who previously had a long career as a food security expert and humanitarian with World Vision, says global vaccine inequity was one factor behind the loss of his own grandmother to COVID-19 last year and has vowed to redouble his efforts to ensure that immunization is seen as a central pillar of global health security.
