A'9' amino-acid sequence 'PRRARSVAS' that CHANGED the world; FURIN Cleavage Site (FCS) insertion in SARS-CoV-2 inserted between S1 & S2 sub-units of spike protein (devastating, pathogenic, infectious)

'PRRARSVAS'; SARS-CoV-2 is only member of subgenus sarbecovirus with FCS; Must investigate EcoHealth Alliance (Daszak), University of North Carolina (Chapel Hill), Wuhan Institute of Virology, USAID
It changed the world. Catastrophically. This 9 amino-acid sequence, where the the purist would argue the 4 amino-acid code PRRA is the key insert, but I am saying we will look at the complete 9 amino-acid sequence starting with amino-acid P ending in S (see embed below). But you should know the PRRA is the devastating insert and it is unique to the initial legacy Wuhan strain that began all this madness.
It is this 9 amino-acid sequence that devastated the world and this 9 amino-acid sequence is the ‘furin cleavage site’ that is inserted to the spike that made the Wuhan (Wuhan-Hu-1) legacy strain coronavirus highly infectious and lethal.
