⁣Until the last six months, Greg Pierson was a pilot with a major airline. He received his first dose of the Pfizer vaccine last August. He went home after the shot, went to bed, and woke up fifteen hours later with his heart pounding at 180 beats per minute. He went into the ER, where they diagnosed him with atrial fibrillation. The doctors got Greg stabilized and his heart rate under control, but he hasn’t been able to fly since and now has to live on disability.
