I think the bug was probably lurking in the filth of Gaza and Hebron all of winter 2020, the way the average Chinese guy in his mid-20s with burner phones and a thousand crypto wallets are now the world's money launderers. Remember Abbas got it in late March 2020 and nearly croaked. Erekat did croak in November.
So given the way the virus cycles they probably did miss the winter 2020 cycle that we had in the US, so they are a full cycle behind, ie, they still have caches of a vulnerable population.
My bet is on “death after vaccine.” We here in the U.S. are up to 2,509 and an update is due tomorrow.
I have read hundreds of our VAERS/Deaths. 1/3 of all of the deaths are occurring in the first 48 hours after vax.
