It need not evolve to be less virulent (selection pressure is transmission, not keeping host alive) so just as dangerous to the immunologically naive *but* those with previous infection/vaccination (thus no longer novel) can experience it as milder. These keep getting conflated.

Also true: even if we experience it much milder *on average*, adding one more seasonal HCoV will add to our disease burden and increase risks for especially for the elderly/immunocompromised. This is true for other viruses, too (RSV even OC43!) but now we have one additional one.

Hence error in arguing merely from "much less likely to get severe disease" (true!) against vaccinating children (especially older ones). Yes, small risk, but adding one more! Also: primary infection with novel virus isn't same process as next exposure.https://twitter.com/loftipixels/status/1448367209680711687 …

I understand, but first, it is not zero. But most importantly, the comparison of vaccine risk isn't to zero risk, it's to risks from getting COVID while unvaccinated. Clearly, both are way smaller risks for children compared to adults, but neither is zero.https://twitter.com/McKotchi/status/1448636692282417160 …

Yes but: studies show that almost all children get exposed to flu before seven or so (also to other human coronaviruses). Here, we are talking about exposure to a *novel* one, while older. Different process, lot more unknowns, and definitely not zero risk.https://twitter.com/atlantictriangl/status/1448639590898679810 …

I'm not dismissing this: of course parents have such questions. However, post-viral myocarditis is also a thing (all viruses! not just this one!) and the correct comparison is the risk after vaccine vs COVID infection. That's what we should compare imo. https://twitter.com/BabeRuthsChris/status/1448640324046295044 …

I don't see how a regular kid—or pretty much any adult in most places, avoids exposure to COVID within the next year or so at most—if not sooner. Yes, risks to kids is *really* low but always the same question: exposure while vaccinated or not vaccinated.https://twitter.com/ariehkovler/status/1448642107737100289 …

These are good questions! I have my own preferences, but that's exactly the correct public discussion, imo. I think we should deeply engage parents with concerns, and address risks as vaccine vs infection with novel virus (something different!).https://twitter.com/colorblindk1d/status/1448644927785635840 …

Also to consider-Pfizer vaccine dose for 5-11 year olds is 1/3 of the adult dose. Post-vax myocarditis risk may well be lower than adult/teen reports. Looking forward to seeing the data.
Thanks. Twitter will use this to make your timeline better. UndoUndo

But the data is showing reinfections are more likely to cause more severe symptoms

Reinfections are a complex thing. I would love to see the data you mention because I have not found anywhere studying it properly. I have been looking for this!
