I received my 2nd dose of vaccine against Chairman's Xi Jingpeng's virus, 1st dose a slight bit of soreness that hardly noticed, 2nd dose the soreness was a little longer lasting but still not bad, but hear that the Moderna vaccine is worse then the Pfizer vaccine that I received, everybody is going to react differently, I took the opportunity because of a auto immune issue that has affected my lungs, hemmed & hawed for a while before going through with it.
