The New Normal: Should we be concerned about our children's immunity?

News 12's Rich Barrabi was joined this morning by Dr. Robert Lahita to discuss mask-wearing in offices.
This is the first week that masks are off at schools across the entire tri-state. They came off Monday in New York City and New Jersey schools. COVID-19 cases don't seem to be spiking - what does this say about the virus right now - and our immunity?
Should we be worried about our kids' immune systems, since they have been wearing masks for the past two years? Are doctors seeing a rise in other common illnesses since the masks have come off?
How should public policy change - as we move forward to an endemic phase?
For people who got their boosters months ago, is their immunity waning now?
