In this episode, an edited version of a live event on November 15, Katherine talks with Seth Berkley, CEO of Gavi, the Vaccine Alliance, about the first year and a half of COVAX, the global collaboration focused on ensuring globally equitable access to Covid-19 vaccines. One year after the first vaccines were made available, their distribution remains highly unequal, with an overwhelming majority of doses so far delivered to populations in high-income countries. Even as vaccine production has expanded, inequities have worsened, especially among lower-income countries. What difficult lessons have been learned over COVAX’s first year and a half? How likely is it that populations in lower-income countries will have access to Covid-19 vaccines in 2022? And how can countries that have surplus vaccines best support COVAX and the distribution of vaccines globally?
