AUSTIN – In a recent essay on Samantha Power, President Joe Biden’s new administrator of the United States Agency for International Development, Michelle Goldberg of The New York Times writes – correctly – that Power’s “first big test … lies in what America does to help vaccinate the rest of the world against COVID-19.” In other words, the “aim” would be to get “at least” 435 million additional vaccine doses to the COVAX facility (the international mechanism established to ensure vaccine access in poorer countries) “by 2022.” If India alone – the world’s largest vaccine producer – could overcome current production difficulties, it could resume exports and start supplying doses to the rest of Asia and to Africa, while meeting its own requirements by the end of this year.
