Remdesivir was never 'preferred' for Omicron, and the successful monoclonal antibody treatment REGEN-COV even had its EUA revoked for Omicron.
They were both Alpha fighters, REGEN-COV being the far more proven of the two.
If doctors are still prescribing remdesivir for Omicron, that's not just a problem, that's a potential lawsuit.
I correctly opined that remdesivir AND REGEN-COV would eventually lead to the escape of a mutation.
Eventually, a South African AIDS + long-Covid patient who had received the gamut of Rx (probably both remdesivir & REGEN-COV; and probably not Plaquenil or ivermectin) had both Alpha and Beta languishing in his system, and he subsequently produced the volatile Omicron mutation just in time for the 2021 holiday season.
