What do I need to know about getting the Covid vaccine? Is it safe?

So I have started my diagnostic imaging program at school. The school itself doesn't require students to be vaccinated but some of the sites where I'll be doing clinicals will require students to have the vaccine. Tomorrow I will be going to the pharmacy to ask for the Pfizer vaccine. Those of you who are well educated on the Pfizer vaccine what do I need to know? There is a part of me worried I will have some adverse reaction to it. I am not allergic or have had negative reactions to anything except amoxicillin and it was still a very mild reaction. Of course I hear about the people who have serious reactions to the vaccines and it does make me nervous.
