I had the Moderna second dose vaccine over 2 weeks ago and am still suffering from the side effects. Day 1 was fine. Day two: headache, nausea, severe fatigue, and joint pain that developed into gout. Today most side effects gone but still fatigued and still have joint pain in knees. Had none of these symptoms prior to vaccine. I have talked to many people who have experienced the same thing with the second dose. I probably would decline a booster shot for the variant.
