After a long ten months, the moment we’ve been waiting for is almost here. This week, drug companies Moderna and Pfizer both announced that clinical trials on their respective COVID-19 vaccines had concluded, and both were found to be 95% effective against the coronavirus. 

While that may be very welcome good news, it comes in the same week that deaths from the coronavirus surpassed 250,000 in the United States. The Atlantic staff writer Sarah Zhang joins Ira to talk about what we can expect over the coming months as these vaccines roll out—with more still to come. Plus, the prehistoric parasites that likely killed a dinosaur, and a scientific debate is sparked on TikTok.
