I assume salt water has lower side effects, so that seemed like a promising thing to check.
Why do you make that assumption? Besides the antiviral effect of it, I would expect salt water to drain H_2O from the oral mucosa. Do you think the effect is too small to matter? Do you think it’s a desirable effect?
There’s a question of how much of the iodine goes to the thyroid and that might produce side effects. On the other hand, the salt water might also have side effects. Do you have reason to believe the salt water to have negligible side effects?

Because I don’t believe the papers saying that iodine doesn’t alter the thyroid.
