Covid-19 milestones: 800,000 deaths, 50 million infections, 1 year of vaccines

Tuesday marks precisely one year since the first coronavirus vaccine shots were going into arms in the US. Over the course of that year, an incredible 202 million people and counting -- more than 60% of the entire US population -- have been fully vaccinated; about 484 million vaccine doses have been delivered; and now the government is encouraging everyone 16 and older to get a booster shot. The number of people fully vaccinated is both incredible and not nearly enough. Fights over how to get the rest of the country to utilize the shots waiting for them have turned into a massive political and legal standoff over requirements.
