⚠️ Emergence of #XAY & #XAW: the NEW complex recombinants of much feared Delta & BA.2 detected in South Africa!
Should we be worried? What do we know about them so far? 1/

A couple of pretty interesting 'complex' recombinants that recently got assigned - XAY and XAW. Both of which are BA.2 x Delta recombinants.
'XAY' contains an immune evasive F486P mutation 2/

XAY found earlier in South Africa has got a very complex pattern of recombination compared to previous recombinants
Both XAY and XAW have a number of additional RBD mutations on top of BA.2 that probably impact antigenicity
