That would be really bad PR if we have players that are not double vaccinated at this stage...or even single dose vaccinated...
I'd guess most are single dosed mate but the players have been jetting off all over the world this summer for one reason or another. Do you think Richarlison, for example, will have had both jabs yet?
It's probably on the clubs to sort but that's hard because each county has it's own rules and only now are we seeing vaccine surplus. Wasn't exactly feasible back in April and May for football clubs to be demanding vaccines to get all their players and staff done was it?
