Most of the folks at work taking thr J&J vaccine have had a reaction to it. Latest was a buddy of mine. He got it last night. I texted him at 6 am. No issues. He texted me at 9 am said he had flulike symptoms. The majority of folks in my department have had stuff ranging from chills, aches and pains, chest tightness, low grade fevers, or extreme fatigue. One of the younger guys said "it felt like I ran a marathon, did a power lifting competition, and played 4 qtrs of football both ways all in the same day".
