Study: Children’s immune response to COVID-19 may be explained

ROCHESTER, N.Y. (WHEC) — Although more children have been getting COVID-19 lately, doctors say their symptoms are still usually far less severe than older patients and researchers believe they finally know why.

A recent study published by “Proceedings of the National Academy of Sciences" identified several factors.


The first being younger kids have fewer ACE2 receptors, which is the area of a cell the coronavirus binds to. It's also possible kids may have had other coronavirus infections, like the common cold, leaving them with cross-protection.

“Kids with asthma and allergies also tend to have higher levels of cells called eosinophils that may reduce their risk from COVID,” emergency medicine specialist Dr. Frank McGeorge said. “Young immune systems may also get a jump start on the virus."

Researchers also suggested children may benefit from a more aggressive, early response by their immune system, preventing the coronavirus from progressing the way it does in many adults.
