I dont really care but it seems pretty obvious that the omicron one has came from a vaccinated person with reduced immunity, i.e. the hiv or similar
These jabs generally restrict anything getting to the lungs but don't actually block infection in the slightest, so it's probably sat there in their system unable to shift it and mutating to remain
By the time it transmits to some nurse or whatever its become less deadly but more transmissible, we should be thanking the vax really
