In international news, South Africa received its first batch of coronavirus vaccines on Monday. The 1 million AstraZeneca-Oxford shots will be used for healthcare workers as they respond to an overwhelming surge linked to a variant that is believed to be more infectious and potentially more resistant to current vaccines.

In Brazil, hospitals in the Amazonian city Manaus report continued shortages of oxygen amid a second, massive surge in COVID-19 cases. In October, medical researchers found about 75% of Manaus’s population had already been infected; many of the new infections are from a coronavirus variant known as P.1 that appears to have evolved to become more likely to reinfect people. A case of the P.1 variant was recently reported in the United States for the first time, in Minnesota.
