So we all know, of course, that young kids seem to have a lower risk of picking up COVID and an even lower risk of becoming severely affected should they manage to get infected in the first place.
No one knows why his is true although the bulk of attention has been paid, I think, to a theory that says that since young kids are sick so often with other coronaviruses (the ones that cause all those colds and runny noses in young kids), perhaps there’s some spillover protection against infection with this novel coronavirus.
But another theory has just been offered up in mBio, an open-access journal of the American Society for Microbiology, that looks to MMR vaccines as a protective weapon against COVID.
These investigators found an intriguing connection between “mumps titer levels and COVID-19 severity in people under age 42 who have had MMR II vaccinations.”
In plainer English that means that the stronger the immune response people under age 42 to an MMR vaccine, the lower their risk of severe COVID.
Now, this was a pretty small study – 80 individuals, only 50 of whom had been immunized – so the results would definitely need to be replicated with much more data.
That said, it’s an intriguing possibility and one I really hope ends up having some validity since it would be a pretty strong argument for the MMR deniers to have to go up against.
