Glad your kids are okay. Looks like Omicron is SO different genetically from earlier forms that natural immunity isn't enough. As you found, most people have symptoms for a couple of days at most. This is typical. Vaxxed just seem to get it more easily but get NO better outcomes, from what I've seen, which is fine because outcomes are just sick for a couple of days. No biggie. Great news about you and your wife. Basic health is key.

Yes....I'd been wondering about the natural immunity part of thing. This kind of confirms that if it is Omicron, natural immunity either wanes by 24 months out or the older Covid doesn't cover it.

Natural immunity lasts for years if not lifetime. It is more likely omi-whatever has nothing to do with the alleged SARS-CoV-2. There is something which obviously is difficult to be immune against - common cold caused by a corona virus.

I have natural immunity from previous November, had a covid case in my family just 2 weeks ago, did not get infected. I am vax-free and damn glad.

A preprint study by very reputable collaborations in South Africa showed that a previous delta infection or vaccination does not protect against omicron infection. But it shows that an omicron infection does confer protection against the riskier Delta strain. It's speculated the Omicron will displace Detal.

Sounds logical to me at this point.

My understanding from epidemiologist substacks is the natural immunity to earlier strains is less effective with omicron.

Natural omicron immunity, otoh, appears to be effective against earlier strains. Personally I consider it the strain to catch...

Yes. I believe this is the study that conclusion was based on, which states that antibodes from either a previous Delta infection or vax will NOT (edit: I left out the "not") protect against Omi but an omicrn infection offers protection against Delta.

Yes, but isn't the focus of the study not on the 13 subjects but on using them as "stock" to extract the virus from their blood samples, to seed Vero E6 cells used for experimenting to determine infectivity and cross-neutralizing between the various mutations of Covid? I myself relied on the summary provided by Dr. John Campbell which the text of the study seems to support to my untrained eyes. If you have a clearer understanding of the study I'd love to hear your interpretation of it.
