What are the symptoms of an allergic reaction to a vaccine?

Question:

I just got 4 shots and about half an hour after, my nose started bleeding and I felt a little nautious. Then, I coughed up a clot of blood and I still feel nautious.

Answers:
there are many signs. An allergic reaction can cause a rash to appear, itching, swelling of the area where you received the shot, and many more, including difficulty breathing.
Go to the ER if you are having bad symptoms. If they are going away, you still need to let your family doctor know. Once you have an allergic reaction, they usually get worse each time.
