Science's COVID-19 reporting is supported by the Pulitzer Center and the Heising-Simons Foundation.

As countries like the United States and United Kingdom inoculate their residents with never-before-used vaccine technology, others, including Russia, China, and India, are investing in more traditional approaches, like inactivated coronavirus vaccines.
