I can speak by experience had Covid in October and never want it again a good 6 weeks of feeling very bad. Recently had Moderna 1 and my reaction to the shot was absolutely horrible so much pain and cortisone shot in my shoulder with opiates got me thru. Month later Moderna 2 hit me exactly 12 hours after the shot intense chills in bed with every blanket we had my shoulders and every joint in my body was on fire and sore. Saw my doctor no idea what causes this they just know it happens to some people others not so much. My wife went thru everything I did covid and shots and she did much better. Younger yes and again doctors don’t know why some have severe reactions others don’t. Imo go into the Covid disease and vaccines with eyes wide open the medical field hopes you do well but bottom line they just don’t know who will breeze thru , who will not do well and in extreme cases those that will die. The statistics just aren’t known yet and governments have made the decisions to move forward with vaccines this we do know. Now it’s your choice no one can force you to take vaccines in the USA at least going into April 2021.
