Sure, give it a shot. A vaccine is basically a delicate cocktail of proteins and salts. Throw it into a freezer that isn’t stable, or a hot, humid room, and you’ll start seeing proteins misfold or clump together. That means it won’t trigger the immune system properly. In real life, that translates to people getting the shot and not actually getting protected, which is a mess. The takeaway? Test the limits, but don’t ignore the fact that a bad shelf life can turn a cure into a risk.

Right. If the cold chain collapses, the vaccine turns into a dud. That’s why you can’t skip a proper stability test. It’s the difference between saving lives and handing out a placebo.

Exactly. Skip the test, and the whole thing falls apart. The only way to keep it real is to test hard and keep the chain tight.
