In the 100th conversation of "You Decide," Errol discussed whether Joe Biden's policies and the ongoing vaccine rollout will have an impact on the pandemic with Dr. Irwin Redlener, who is the founding director of the National Center for Disaster Preparedness at Columbia University's Earth Institute and a public health analyst for MSNBC.

As the death toll surpasses 400,000 and the U.S. marks one year since the first positive case, Redlener explained what the year ahead will look like, and he talked about the anti-vaccine movement.

He also discussed his efforts to help provide health care to underserved children and the state of child homelessness.
