I am a long, and this is complete fantasy. I would put it up there with the same fantasy delusions the shorts have.
If you had GBM (or any other solid state cancer), would you want your $200k, life-depends-on-it, DCV-L shot being handled by your local Walgreen staffs, or a dedicated oncologist? That thought of that is half-funny, half-sick. And that is even if Walgreens would be willing to process a $200k insurance co-pay.
You cannot compare a $2/dose COVID jab to a $200k personalized dendritic cell vaccine.
