#加速主义#It Is Not Too Late To Achieve Global Covid-19 Vaccine Equity

Gavin Yamey and colleagues say that a new, urgent push for global vaccine equity could help avert suffering and deaths, protect economies, and prevent new virus variantsDuring the covid-19 pandemic, we have seen the best of international collective action and its limits. Global scientific cooperation drove the development of safe, highly effective covid-19 vaccines in under one year.1 Yet we have also witnessed global vaccine inequity,2 in which low and middle income countries have “limited supply and limited vaccine brand options.”3With the omicron wave dissipating, several well vaccinated high income nations with stockpiles of covid-19 vaccines are rushing to declare the pandemic over, reminding us of how things unfolded with tuberculosis, malaria, and HIV/AIDS in the past. But the pandemic is not over and 2.8 billion people remain completely unvaccinated. Now is the time to recommit to, and further invest in, equitable and effective country led vaccination campaigns.In this paper, we briefly examine how global vaccine inequity arose, lay out a renewed case for urgently ramping up our commitment to vaccine equity, and propose principles to ensure no one is left behind in the quest to vaccinate the world.High income countries quickly pre-ordered huge numbers of doses from companies such as BioNTech/Pfizer that overcame early manufacturing scale-up challenges relatively quickly.6 In contrast, low and middle income countries, as well as the Covid-19 Vaccines Global Access (Covax) facility that purchased doses for distribution in these countries (box 1), largely relied on initial purchases from Astra Zeneca, Janssen, and Novavax, which were slower to overcome manufacturing scale-up challenges.
