Keeping children masked and separated is necessary. It could also undermine their bodies’ ability to learn how to fight pathogens.
During the Covid-19 pandemic, the world is unwittingly conducting what amounts to the largest immunological experiment in history on our own children. We have been keeping children inside, relentlessly sanitizing their living spaces and their hands and largely isolating them. In doing so, we have prevented large numbers of them from becoming infected or transmitting the virus. But in the course of social distancing to mitigate the spread, we may also be unintentionally inhibiting the proper development of children’s immune systems.
