US may be turning a corner on Covid-19. Here's when we could see cases and deaths plummet, expert says

While the pace of Covid-19 vaccinations may be slowing in the US, experts are optimistic about where the country will be in just a matter of weeks. 'This summer is going to seem so much closer to normal than we've had in a very long time,' Dr. Jonathan Reiner, professor of medicine and surgery at George Washington University, told CNN on Sunday. 'The key statistic to think about is ... what percentage of the adult population has received at least one vaccination.' Roughly 58% of US adults -- and nearly 46% of the country's total population -- have received at least one Covid-19 vaccine dose, according to data from the Centers for Disease Control and Prevention. More than 34% of the US population is fully vaccinated, CDC data shows.
