When confirmed the name of the vaccines as Pfizer COVID 19 Vaccine, Reporter stated, Yeah, I had received it as well yesterday the only side effect that I experienced is that I am still experiencing is joint pain but that's not anything I would really call about because I've already had some sort of joint pain before this just amplified it a bit.

It's, not like call 911 but he definitely since yesterday and still today that he feels tightness of his chest, he have had shortness of breath, things like that.
