You should ask your doctor. Not just a yes or no question, but have a conversation.

If your primary care physician can't address your concerns, as you've stated them here, then get a second opinion.

That said, myself and my family have taken the full course of mRNA vaccines from their earliest availability and continue to get boosters. One member of my family has a chronic illness and has also taken all the vaccines. None of us have had any side effects (beyond soreness from the injection site and maybe lethargy day of vaccination) and none of us have tested positive for COVID or been sick. That's my one data point for your collection. :-)
