'Kids need to be in school.' Updated COVID guidance from Children's Hospital

The last two years have been very hard for schools trying to come up with policies to keep kids and staff safe during the COVID-19 pandemic. One of the key groups that has helped schools create policies during the pandemic is the Children's Hospital of Philadelphia PolicyLab. They recently updated their guidance for schools, so KYW Newsradio's Jim Melwert reached out to PolicyLab's Director Dr. David Rubin to ask what changed, why, and get his thoughts on where we are in this pandemic and why it's different than a year ago.
