Herpes is a normally-dormant virus that, when it flares up, causes those annoying blisters, until it goes dormant again. Tons of people have this problem, it's extremely common (this virus causes cold sores, canker sores, etc. Probably most of the population has this virus.). So sure, if you can find some kind of antiviral that suppresses or kills the virus, you can avoid those blisters. And luckily, the effects of herpes simplex are almost always minor and temporary in nature, not life-changing. What we're talking about here with polio isn't suppressing or eliminating a virus, we're talking about fixing damage caused by a viral infection to the CNS. At this point, the polio virus isn't even a problem: people who recover from it don't have the virus anymore, they're just stuck with the damage it's caused, much like people today with "long Covid". This isn't something that's going to be easy to fix.
