More than 64 million people were vaccinated against the novel coronavirus as of Saturday, including 20.5 million Americans. Just as more vaccine supply became available, several mutated coronavirus strains have begun spreading more efficiently than ever, including one that might impact vaccine efficacy. As of Monday morning, nearly 100 million have been infected, and more than 2.15 million people have died of COVID-19 complications. Governments around the world are now looking to speed up vaccination campaigns, with President Biden having committed to vaccinating 100 million people in his first 100 days in office.
