Fireflies are retarded and Joel did nothing wrong.
a surgeon THINKS he could possibly create a vaccine
he's a surgeon, not a biochemist so he knows how to operate a brain but doesn't know how to synthesize anything from the brain, surgeons dont do that
if he could, how would he replicate the vaccine?
if he could replicate the vaccine, how would he manifacture it? Does he have a labratory with other scientists who can do that?
if he has a lab and scientists, where would he get enough materials to create enough vaccines?
if he had enough materials to create a shit ton of vaccines, how would he distribute it?
this whole project can take months, possibly years because manpower shortage
even if you couldn't get infected, the infected will still swarm, attack and kill you
vaccine wouldn't change anything, people and communities would still fight over supplies and resources
nothing changes
Fireflies were chasing a pipedream
