As one who lost a Grandfather and two Granduncles to the Spanish Flu..., I would only point out that it's occurrence was prior to the advent of antibiotics.
Hot toddy guy claims he refused antibiotics
Antibiotics are pretty much useless against a virus.
Vaccination was the way to go but you can’t use it against unknown.
Real antiviral drugs were first developed to counter AIDS and yet to prove to be really effective.
My Grandmother died of the Spanish Flu. My Dad was 5 months old.
Antibiotics do zero/nada/nothing for any and all viruses. In a few cases they may prevent secondary infection but these infected people are primarily dying because their own immune system causes swelling in the lungs and fluid accumulation and they essentially drown in phlem. (Cytokine Storm)
Antiretrovirals may... and this is a big maybe have some treatment effect as might strong anti-inflammatories. Prone position induced coma with low volume artificial respiration may also help. Treatment is essentially keeping the person from drowning while their body fights off the virus. The Spanish Flu killed in the same manner.
There are a lot more cases than are reported and/or diagnosed. Some who get it are not stricken down with severe symptoms. I have seen numbers of from 90,000 to 165,000.
A virus isn’t a living germ. It’s a bound-up chemical, against which an antibiotic is useless.
Where are the materials for antibiotics sourced from? Did I hear China and India?
How much is in-transit in the distribution pipeline? What reserves are already warehoused in the country?
How long to source materials and set up an alternative manufacture of the needed antibiotics within the country?

As one who lost an uncle and all most my dad, antibiotics would not have worked then, in between and now against any virus.
