Steve and CSIS Senior Fellow Katherine Bliss enjoined Sir Andrew Witty to help us answer a few fundamental question: what exactly is this new, umbrella coalition, the ACT Accelerator; what is its value, six months after its creation; and what are its true prospects of success in battling hyper-nationalism and enhancing access by low and middle income countries to Covid-19 vaccines, therapies and diagnostics? Along the way, we delved into the significance of the November 21-22 G-20 summit, discussed the finance gap, the prospects of massive vaccine surpluses in the hands of the most wealthy and powerful countries, and China’s participation. Is the door open for the United States to join, belatedly? And what would the special value of that be? Andrew Witty is the Co-Lead of the Access to Covid Tools (ACT) Accelerator and WHO Envoy for Covid-19. Between 2008 and 2017, he was the chief executive officer of GlaxoSmithKline. He is currently president, UnitedHealth Group, and chief executive officer, Optum.
