Experts know more about the coronavirus vaccines than any other in history, surgeon general says

Great news emerged Sunday on the vaccine front, as a second Covid-19 vaccine will soon be available to some Americans. But for much of the US, the pandemic is raging out of control -- and will get worse before everyone can be vaccinated. In just the past week, more than 18,000 people died from Covid-19 in the US. Hospitals are filling up fast. And the US set a record Friday for the most Covid-19 infections reported in one day: 249,709, according to Johns Hopkins University.
