Important factoid just making the rounds.
2/3 of US infections as of January in Omicron dense regions are re-infections. Recovered immunity 1) doesn’t last long and 2) doesn’t prevent omicron infection.
We’ll need some time to see if omicron’s recovered immunity duration is also short.
That would be my guess. We'll enjoy it while it lasts. I think we've learned enough from Alpha, Delta and other variants that this appears to be the case, unfortunately. We'll have to keep this in mind 6 months from now (or in a year) when the next variant may emerge.
