When people use the term "medicine" or "drugs" when referring to vaccines it's a good indicator they're either being disingenuous or don't know what they're talking about.

The way drugs interact with your body is incredibly complex and difficult, if not impossible, to fully monitor. You're putting some molecules in your body and hoping they'll end up doing x without knowing what else they might be effecting. Throw in another drug or medical condition that might interact with the first and it gets very crazy very fast. This is why most drugs require prescriptions.

Vaccines on the other hand are very straight forward. They mimic a the natural process of a foreign virus or bacteria entering your system and being found and eventually neutralized by your immune system, training it to know what to look for in the future in the process. It's inherently vastly less complicated with essentially no long term risk that could crop up out of nowhere.

If a knowledgeable person was truly concerned about a vaccine causing long term issues, they'd be absolutely terrified of every virus or bacteria entering their system since those have had no previous testing and will multiply many, many times more than the contents of a vaccine.

Vaccine adjuvants are not at all straightforward. The mechanisms of action are complex and poorly understood.

Despite the unknowns, approved adjuvants are very safe and the presence of adjuvants isn't a reason to avoid vaccination.
