Healthcare advocates on Thursday welcomed a pledge from presumptive Democratic presidential nominee Joe Biden to share any potential Covid-19 vaccine with the rest of the world if elected, calling it an important "step in the right direction" that must be followed up with a substantive plan to reverse President Donald Trump's "America First" approach to the global pandemic.

"Covid-19 technologies must be treated by the U.S. and all nations as global public goods," said Emily Sanderson, an organizer with Health GAP, an international advocacy group dedicated to expanding global access to medicine.

"Hoarding, nationalism, pushing people in low-, middle-income, and other upper-middle income countries to the back of the line, blocking healthcare workers' access to life-saving personal protective equipment, and buying up supplies of current and prospective treatments is a losing prescription for the American people," Sanderson said.
