a big part of the initial scare story on COV19 was "it's a zoonotic virus to which humans have no pre-existing resistance."

it was never true.

yet another study showing that over 80% of non-exposed individuals already have cross resistance to covid 19.

this is important in several ways.

1. this resistance is predominantly t-cell mediated. antibodies need not develop and antibody testing is going to miss a lot of cases AND a lot of resistance.

there is a reason they do not use IgG tests to measure epidemics.

2. it shows that the best responses were broadly activated t cell response. it implies that resistance here has many facets and that if your t cells recognized and attacked covid in a variety of ways, you got a mild case.

this makes resistance look plausible and durable.

3. it also makes vaccines look much more difficult and herd immunity more important.

effective resistance is not so much a silver bullet as a gang tackle.

this fits with children (whose immune systems are less calibrated an more likely to attack things) getting so little cov

4. it also fits with this finding that memory t cells have durable resistance to sars-1.

it's not about "antibodies". it's about broad activation of a variety of t-cell responses. https://twitter.com/boriquagato/status/1284134457348362240?s=20

5. this also fits with this theory on asia.

the whole pac rim and china adjacent world had the same incredibly low covid death count.

it's because they've had more exposure to sars-like viruses and thus have the t-cell memory to mount broad responses. https://twitter.com/boriquagato/status/1280212958392446977?s=20

oh, sure, you might say. hindsight is 20/20.

but this was glaringly obvious right from the start.

this is what certain internet cats were saying on march 17th (and getting shouted down over)

this is just basic virology. https://twitter.com/boriquagato/status/1239988242570608640?s=20

remember that now as the same folks that told you of 2 and 4% IFR and millions or 10's of millions dead preach "second wave" and ignore every standing bit of pandemic policy to push lockdowns and travel bans and masks that are KNOWN not to work.

it's just theater.

none of these claims and models were true then and almost none of them are true now.

it's a carnival of fear mongering, crony capitalism, and partisan warfare.

and we're all caught in the middle.

but the facts are the facts.

disease resistance to cov19 is real and durable, vaccines uncertain and unlikely in a relevant time-frame anyhow, and herd resistance clearly works and is achieved in the 10-25% infection ranges depending on the location.

the clear play is to generate low risk immunity.
