Dr. Jonathan Samet, an epidemiologist and the dean of the Colorado School of Public Health, said that he hopes people will continue to be vaccinated in large numbers, which will help reduce the spread of the pandemic, and urged people to continue other precautions, like masking and distancing, until coronavirus numbers recede. "I don't think anyone would have thought we'd be looking forward to summer where we're mostly vaccinated," Samet said. "A year ago, that was not a prediction I would have made. I think we can look forward to a summer that would be far better than I thought it would be."
