Did pandemic lockdowns stunt kids’ immune systems long-term?

The COVID-19 pandemic drastically reduced people’s in-person interactions with others as events were canceled and people limited their excursions, and many also practiced social distancing and masked up if they did go out. These moves were intended to control the spread of the disease and were shown to help flatten the curve.  

However, some concerns have been raised about the potential impact of these actions on children’s immune systems, and namely, kids’ ability to fight infections. But did COVID “lockdowns” and other pandemic-related restrictions actually stunt kids’ immune systems?
