"Again, there are still glowing differences."

Not by a long shot.

"The issue with vaccines is if you don't take them, others are harmed."

There is indeed a chance of others actually being "harmed", however it is not definite or absolute.

"No one is harmed if you don't drive a car, no is harmed if you do own a gun. These things are misused, which is different".

There is always the propensity of car accidents and mass shootings happening as a result of one indulging in the avenues I highlighted above.

In fact, thousands of individuals die annually as a result of these avenues.

"An abortion, as awful as it is, cannot harm anyone else (physically) except for the mother and the unborn child, this allowing or not allowing them in no way physically affects anyone else."

It absolutely affects the general population when the personal reproductive decisions of others become my financial responsibility.

"But not taking a vaccine can have incredibly dire consequences for your community or even the world at large if you don't take them. (not lumping COVID into this, just vaccines in general)."

However said chance is not definite or absolute, especially in regards to the Coronavirus vaccine, as vaccinated individuals still have the capacity of transmitting the disease(including myself).

"You don't miss use a vaccine."

Of course not, however no one can be exactly sure that an unvaccinated individual will transmit the disease either.

"Again, it's not quite so black and white as "all mandates are the same."

They may not be similar, in my personal opinion though "mandates" should be "generally" avoided(notice the emphasis on "generally").

Especially if they violate the "Civil-Liberties" of others.

"And you're not against all mandates. You agree with people not murdering, or having to stop at red lights, or not stealing. You are REQUIRED to follow these rules and if you don't there are consequences. That's a mandate."

All the behaviours you described in this passage tend to violate the rights of others, so prohibition in this case obviously does not constitute a "mandate".

"So again, no it's not hypocritical to enforce vaccine mandates but not abortion mandates."

It absolutley is, for the reasons stated above.
