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.
Yes, you were probably immune to that particular cold strain. Or you weren't in close contact with your wife during that timeframe, but that wasn't the case for the persons I've written about.
It's hilarious that in a thread about misinformation the idea that children are immune is being treated as not true. Death rates for COVID for people under 20 are ~zero. Babies are in fact immune, perhaps due to relatively lower levels of ACE2 expression compared to adults.
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.
First off, you're moving the goalposts a bit here. No one claimed that the death rate for people under 20 was anywhere near that of older age groups.
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.
Remember you're dealing with a very noisy, FP-prone test, and there have been millions of tests by now. At those levels there are bound to be some babies that tested positive and then died, so you can't infer from it that COVID actually killed them.
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".
If you're going to ask him to share sources, please show some of your own with the level of rigor you would like to see to the contrary. I'm tired of this trend of people shouting Sauce! Sauce! At each other. Collaboration is key.
