The extent of vaccine nationalism, however, may strongly impact global trajectories of COVID-19 case numbers and increase the potential emergence of novel variants, according to a Princeton University and McGill University study published Aug. 17 in the journal Science.

A new technology being developed by Princeton University researchers and alumni could offer a more effective and robust delivery method for COVID-19 vaccines.

One early feature of reporting on the coronavirus pandemic was the perception that sub-Saharan Africa was largely being spared the skyrocketing infection and death rates that were disrupting nations around the world.

On April 1, 2020, as the pandemic threatened to overwhelm area hospitals, Andrew Leifer was looking for a way to help.
