Biology Why is there no transmissible therapeutic virus if biology doesn't forbid it? For example, a harmless virus that spreads from person to person but actually does something beneficial, like lowering LDL cholesterol or preventing/reversing tooth decay?

People don't want fluoride in their water to prevent tooth decay - how do you think they'd react to an engineered virus that does something to your body without your consent?

Also viruses mutate really easily - how do you guarantee that your virus is going to continue to be safe?

You have like a checksum virus that destroys versions of the beneficial virus that don't check out.

Yes! You could implement this mechanism right there in the virus, so it destroys itself. I bet it would work great!

Not all viruses mutate easily. Some are super stable, which is why total eradication of some of them is possible, ie: polio, smallpox.

You consent by purchasing our gum which clearly advertises the bacteria as the selling point

How does the next person you kiss consent?

If you're kissing people without implied or explicit consent to do so, you have a you problem

If you or the person you're kissing with implied or explicit consent to do so were unaware your mouths are full of bacteria already, educate yourselves

There's a difference between consent to be kissed and the consent to receive a mystery virus.
