'Unethical and unconscionable': Should young Americans get COVID-19 vaccine before poorer nations' most at-risk?

While images of people lined up for long-awaited COVID-19 vaccinations spurred hope in millions across the globe, they stirred up something else in Dr. Juan Jose Velez: frustration. Velez runs the coronavirus ward in one of the biggest public hospitals in Colombia, a country with one of the highest death rates and positivity rates in the world. While more than 152 million COVID-19 vaccine doses have been administered globally, with roughly a third of those in the U.S., according to Bloomberg's vaccine tracker, Colombia is among a number of lower- to middle-income countries that still had not administered a single dose by mid-February.
