You don’t need to trust the government. You can do your own research by starting with some biology textbooks and then progressing to immunology, the history of medical science, etc. Then you can read a bunch of papers on mRNA vaccines and learn exactly how they work. There is a ton of international clinical data available too, which at least means you don’t have to trust just one government.

Note that nowhere did I mention YouTube videos, celebrities, or talk radio blowhards.
