Laden with expletives & name-calling directed at the deliberately misinforming group determined to convince you that SARS-CoV-2 was an entirely new form of biology & that immunity did not or could not result from it.
This overview deliciously confirms what some of us have been trying so hard to communicate for a long time now. Infection by SARS-CoV-2 - or vaccination with a SARS-CoV-2 active ingredients - produces real, solid, functional immunity.
The studies in this article show that an infected human produces an immune response—they developed immunity—to SARS-CoV-2, which helps to protect them from infection by the same variant. Immunity makes it really hard to intentionally infect that person with the same variant.
The same principle applies to vaccination - especially when well-matched with what's around - which is how it saved so many lives when used early on (see Australian and New Zealand examples), reduces the occurrence of long-term COVID-19, and makes disease outcomes less serious.
The new study shows that once there's immunity to a variant, it takes SO MUCH MORE (10,000X in one study) of that variant to kick off a 2nd infection. Thanks immunity that does exist, is produced and protects us.
Unfortunately, the term “reinfect” was never defined; it was just used incredibly lazily and without thought. And so, it was taken to mean infection by any variant. Which it shouldn't have been. It should have been used with a definition, for example:
..Reinfection is either by the same variant (which is not very common because IMMUNITY) or by a newly evolved variant (which is pretty common and is what we mostly see with SARS-CoV-2 "reinfection"). Despite wanting some clarity, it never emerged.
Immunity exists to that which triggers it. But if a new variant emerges, it has BY * DEFINITION done so because it changed itself to escape previous immune system recognition. That’s why we see one variant REPLACE another instead of the same variants causing multiple epidemics.
Of course, our vaccines have not been good enough to prevent everyone getting seriously ill, & they can’t work as well for those with certain predisposing factors. We’ve also been pathetically slow at rolling out new variant vaccines and so, apart from the very early days...
