You are over generalizing. Yes, propaganda has been used to promote causes. That does not make the support of your claim. Your claim is on the order of saying "German shepherds are dogs, therefore this dog:

As you see even he is confused by that claim.
I can't find my reply to you unfortunately. But if I remember, according to history and purpose of propaganda the cause prompted is getting the vaccine because of the pandemic.
1. Marketing: like the mc Donald's picture I showed. Amazon products.
2. Language, analogies, and sayings
3. Communication theories. Experts and people studied how media affects people's emotions and behaviors. I linked them but I don't know if it was to you or not.
4. Censorship. Assuming anything that challenges vaccines is misinformation. Outside of conspiracy theories, skepticism is healthy when making healthcare decisions.
5. Logical fallacies (I won't list though political like religious topics there are a few repeated fallacies do noticed.
There are others.
The thing is this isn't charging facts. There are experts who do but because it distracts people from the cause it's deleted.
I just disagree with it. It's causing political division and people don't care or see it because saving lives as an immediate goal overlooks long term effects.
Anyway.
Usage of propaganda in causes is a fact. There's lots of examples but, well, coming from an unvaxed person it's see differently.....
Which is a huge problem. When you judge the validity of information based on who said it you (people) can do that when they listen to opinions and decern the facts from media and it can cause confirmation bias...
Edit.
I can give expert citations to this information for technical reasons. I'm just quoting what I've observed, evidence, and facts from history and all of that.
Media influence, usage if propaganda, etc are interesting topics. But, well,
