Utter BS.
If that's supposed to be based in 'science', it's political 'science'...
We have been forcing the entrapment of virus’s and pathogens against our children’s face with forced masking. That couldn’t be it right? /s
What response to a coronavirus became the new normal when it came to children? An approach that was never in play except for children at high risk should they contact a virus. I can think of two. Universal masking and social isolation.
Perhaps these meant their immune systems were not able to build up a robust defense against common usually mild viruses.
They are just trying to cover for mRNA vaccine caused immune suppression.
