The U.S. Food and Drug Administration approved the Pfizer-BioNTech COVID-19 vaccine on Monday. 

The vaccine will be marketed to people 16 and over to prevent the spread of COVID-19, but will still be available for people 12 to 15, according to an FDA article. 

The vaccine is 91 percent effective at preventing COVID-19, according to the article. 

WSU students now have 45 days to receive the vaccine or a medical or religious exemption from the vaccine, said Phil Weiler, WSU vice president of marketing and communications. 

Students will not be able to register for classes in the spring, according to a Daily Evergreen article.
