This was posted on /r/news and everybody thinks this is about the anti-abortion laws. If you read the article, it's actually because of covid (this is not me saying anti-abortion laws won't have an effect, that's just not what this current issue is about).
That's actually the reason I remembered this, because the "Immunity Debt" explanation was kind of blown out of the water by the uptick in RSV from children who weren't around for the "dreaded" era of masking.
