When you hear about pledges to increase immunization in countries like Haiti, where 69 out of every 1,000 children die before their fifth birthday, Gavi—the Global Alliance for Vaccines and Immunization—is probably behind it. The organization, started in 2000 with the help of the Bill and Melinda Gates Foundation, brings together key UN agencies, governments, the vaccine industry, the private sector, and civil organizations with a shared goal of creating equal access to vaccines for children living in the world’s poorest countries. Here at Okta, we contribute to the Gavi cause through the Okta for Good program, which supports nonprofits through free product licensing and preferential pricing. We spoke to David Nix, chief knowledge officer at Gavi, to learn about his role in the organization’s aggressive goal to immunize another 300 million children by 2020. What were some of the IT challenges you faced when you started at Gavi.
