I'll point out that when we talk about how "oh it'll only be bad if you have comorbidities too", I'm pretty sure more than 75% of the US qualifies as having those. I'm not paranoid by any means, and I don't want vaccine apps or centralised databases to exist (anonymously signed timestamped attestations maybe), but the vaccines are not 100%, and my risk model dislikes being stuck next to someone dumping out virions for over 8 hours a day with recirculating air.
[side note: I've also worked retail in the past and that taught me to never trust the general public, and that some idiot parent absolutely will bring a kid in with measles, norovirus, and smallpox in at the same time while lying about how they're healthy so they don't get charged a $10 cancellation fee.]

Do kids even need it? I was under the impression that child covid deaths (or even just severe reactions to the disease) were incredibly rare.
