The race to defeat the coronavirus can be viewed in two very distinct ways. One is based on international cooperation, with a vaccine treated as a "global public good." The other is competitive, a battle between nations that's being described as "vaccine nationalism."

As COVID-19 continues to spread across the country, state and local health officials rush to try to detect and contain outbreaks before they get out of control. A key to that is testing, and despite a slow start, testing has increased around the country.
