Also, turns out preventing kids from getting sick improves educational outcomes.

My dad made a similar observation, assuming the children were young. However, upon reviewing the article, I noticed it doesn’t explicitly mention the grade level. Considering younger children have weaker immune systems, this could potentially lead to fewer missed classes and improved grades. Personally, my first grader misses out on a considerable number of classes.

However, if these results were observed in grades 3 or higher, it could suggest a more substantial phenomenon. I randomly picked the third grade, but perhaps there’s a specific age after which the medical community considers a child’s immunity to be significantly enhanced.

It's not that they are weaker, but that many things actually confer long term immunity. The "common cold" is actually many viruses, once you've beaten one it's not likely to get you again but it's cousins will.
