On Monday, the U.S. Centers for Disease Control and Prevention issued new guidelines on how fully vaccinated people can gather with others. I think these guidelines do a nice job of balancing data around decreased transmission of coronavirus from people who are vaccinated and the continued risk of community transmission because so many people are not vaccinated. The biggest part of what vaccines do is prepare the immune system to respond to an infection. In the current setting, because so few of us are vaccinated, I think the cautious approach is the right one. And guidelines that allow vaccinated people an incremental return to normalcy help that.
