However, this does not compute with veterinary antibiotics (essentially the same as human antibiotics, and work in humans, but are far less controlled and monitored), that are useless against viruses.
Unless the tangible threat is of a weaponized bacteria that is susceptible to those particular antibiotics.

May or may not be relevant, but someone I know who works in a vet practice was informed by suppliers a few weeks ago that all meds are going way up in price. Some common antibiotics, like doxycycline, already have. There has been such a rush on various tetracyclines that dispensing veterinarians are back ordered.
I assume this will be true for the same meds dispensed by pharmacies for human use.
