FDA is running ads for pharma because OPDP would go after pharma if they ran them themselves. Current federal regulations forbid advertising of EUA products (which is what these new mouse shots are) without massive disclosures in the ads themselves about how they're EUA, not approved, and we don't know whether they're safe and effective. It must be so awesome to be Pfizer and have the taxpayer foot the bill for an ad that would get shut down in a heartbeat if you ran it yourself.
