Are you referring to the Omicron variant? Current theories suggest that Omicron evolved inside a HIV patient. There is no reason to believe the patient was vaccinated.

Omicron evades the body’s antibodies generated from infection by the delta or alpha or wild type variants, so there’s no plausible case for vaccine “selective pressure” especially as it emerged from a region of the world with very low vaccination rates.
