Some degree of caution is warranted on the part of the individual when unwelcome side effects manifest following a drug or vaccine. Doubly so when you can find cases where others have reported the same side effects.

We are also dealing with a novel (and evolving) virus and an even more novel set of vaccines. We're still learning about both. I find it silly that one could possess hubris about their stance on such a matter.
