My feeling is that they deserve "The cure" blowing up in their face. No one bothered to really grill Eugene b4 committing to drop everything and go on this quest. They basically accepted, "You wouldn't understand".
In one episode he made a feeble attempt to vaguely explain, but no where near enough for them all to simply accept it.
I'm no scientist or biologist either, but I would have wanted more info than what satisfied them. Ricks original crew had the advantage of some knowledge about how the virus works (from the CDC guy in the first season). They should have at least quizzed Eugene to find out if he knew that much.
Also, Eugene spoke about wind currents and pollution, neither of which were relevant as the disease isn't transmitted that way. And since they had not yet synthesized a cure, they could not yet have devised a way to distribute it.
Otoh, people vote for politicians based on less than that, so it is plausible - and we all pay the price for that.
