Some people are indeed immune to covid, babies too, most probably. I've personally heard of numerous cases of persons not getting the virus at all while their spouse was in intensive therapy or worse.
HN readers seem to have totally lost it w.r.t. COVID and misinformation. It's practically guaranteed that in any thread about misinformation/FB/Twitter/etc someone will state something about COVID that's true and then describe it as misinformation, or state something about it that's false and then decry the conspiracy theorists who don't believe it.
Your assertion that "babies are in fact immune" is demonstrably false: https://data.cdc.gov/NCHS/Provisional-COVID-19-Death-Counts-... shows 20 deaths for children under 1 year old. Presumably many more than that were infected but survived (unfortunately covid.cdc.gov is timing out for me right now and a quick search didn't give me infection rates for that age group).
Yes, the number is small compared to cases in older people. But "babies in fact are immune" is in fact the same kind of misinformation you're railing against.
To put it in perspective, according to the UK govt's own analysis, it's very likely that all currently reported positive infections are false positives!
Later edit: To add to my comment, what do you call sleeping in the same bed, eating from the same plate and having direct physical contact with a person who gets the virus and ends up in IC or dead while the other person tests negative for the virus?
Let's not forget that ever since February we've all known that this virus is particularly easy to transmit/get, so you cannot say "that person got really lucky, that's why he/she hasn't got it".
