It seems that some are hesitant to get the vaccine because they are concerned about long term effects. I haven't looked into that enough to develop any significant level of expertise, but so far I don't get the concern.
This is what's in the Pfizer vaccine. I focus on that one cuz that's the one I got. [

Lipids – The following lipids are in the new COVID vaccine. Their main role is to protect the mRNA and provide somewhat of a “greasy” exterior that helps the mRNA slide inside the cells.
((4-hydroxybutyl)azanediyl)bis(hexane-6,1-diyl)bis
(2-hexyldecanoate), 2 [(polyethylene glycol)-2000]-N,N-ditetradecylacetamide
1,2-Distearoyl-snglycero-3- phosphocholine
cholesterol
Salts – The following salts are included in the Pfizer vaccine and help balance the acidity in your body
potassium chloride
monobasic potassium phosphate
sodium chloride
dibasic sodium phosphate dihydrate
Sugar – Basic table sugar, also known as sucrose, can also be found in the new COVID vaccine. This ingredient helps the molecules maintain their shape during freezing.So... fat, salt, and sugar. And mRNA molecules.
The poloyethylene glycol (aka PEG) in that second lipid has been a suspect in some alergic reactions.
From this article: [

There is only one ingredient in the vaccine, called PEG, that could potentially cause an allergic reaction, but experts agree it is unlikely to be a problem for the vast majority of people.
PEG "is a very common inactive ingredient found in a lot of over-the-counter things and in a lot of injectable medications," Dr. Erin L. Reigh, a staff physician in the Section of Allergy and Clinical Immunology at Dartmouth-Hitchcock Medical Center, told ABC News.
In fact, PEG is so commonly found around us that "you probably ate it this morning," said Stukus. "It is in many different foods and medications. It's in in MiraLAX, for when people are constipated. It's present in some other vaccines as well."Even considering that, though, those vanishingly rare allergic reactions occur shortly after the vaccine is administered.
I can't find anything that makes me think this vaccine can cause any issues down the road. From what I've read (and as I understand it), everything in the vaccine - mRNA, fats, salt, and sugar - are processed within weeks of the vaccine and are no longer present in your system after that. Same thing for the proteins that the body produces: the body's immune system activates and destroy those proteins and after that they're gone as well. After a couple weeks all that's left is your immune system's memory of what that protein looks like. The question I keep asking: how can the vaccine cause any issues down the road when every component of the vaccine is eliminated from your system in a couple weeks?
