surely an immunologist wrote that definition, and didn't leave out a single detail or important context.

anyway,
@-=SS=- your claim of it being akin to a saline solution is more what i was going for (if you've got
good evidence to present for that, please do) but i'll bite:
Complete protection against infection has long been hailed as the holy grail of vaccination. It might simply be unachievable.

Vaccines are used to boost your immune system and prevent the risk of infection and the severity of infections, including those that cause serious, life-threatening diseases.

we now know that they aren't as effective as the cdc was claiming (and the dumb assholes told us we could go around vaccinated people, unmasked, with our unvaccinated children), but they are still quite effective at preventing severe disease and death.
they, in fact, stimulate our immune system to not only make antibodies, but also tell our b cells and t cells to snap a memento for future introductions of similar coronaviruses.
our immune system isn't just an on-off switch that goes from 0% immunity to 100% immunity.

They might as well be saline really.
it's like saying seatbelts do absolutely nothing because they don't perfectly prevent you from injury or death in a car accident, and might as well be a shoestring.
i'd rather get a moderately effective vaccine than go into cootie- town with nothing. ymmv (depending on how bad at statistics you are)...
