I think most people would rather be led by religion or rhetoric than science. Both the previous things are somewhat cultish & what they state is fairly set in stone. Science at its core should always be evolving with exposure to new information & current events. Religion is a dead thing, a fossil made of old ideas . Science is dynamic. It's adapting, adjusting & refining as it encounters new or further phenomenon.
Do you want a rigid life where the rules are engraved in granite, then religion's for you. If you want to move forward, however frustrating or frightening that may be, look to science. There's the old line, "To boldly go..." Star Trek had ideology & science, not religion. Where the federation got into trouble was when it relied to heavily on it's own rhetoric instead of adapting to the situation.
You have a choice, move forward or stick your head in the sand. There will always be new information, findings, discoveries, formulas, etc... For better or worse, even after decades, new finding still emerge about HIV meds.
But with that new info, they can adjust. That's the way of science. It won't bring the comfort of absolute certainty. But it can give the assurance, it's probably the best currently available & it'll keep looking into the matter. Science isn't a short race with a finish line. It's a long haul, marathon with goals along the way. Passing mile markers doesn't end the endeavor.
Cya...
