Key points

1. Mark Chapman, 66, a former Sea King helicopter pilot with about 30 years of military service, later flew offshore oil-and-gas helicopters and captained an amphibious Harbour Hopper in Halifax.
2. He says his licenses required regular physicals and he had 47 years of documented good health, including cardiac health, and was very physically active before vaccination.
3. He received three Pfizer shots and says the day after his third, on December 20, 2021, his Apple Watch flagged atrial fibrillation and tachycardia.
4. He describes ongoing cardiac problems, chronic fatigue, chronic full-body pain, numbness, muscle contractions, gastrointestinal issues, and cognitive and memory decline.
5. He recounts being unable to deliver a presentation he had written and forgetting routine tasks, ending his career training pilots in flight simulators.
6. He says he passed out and was picked off the floor five times in one summer, and in June 2025 suffered an ischemic colon requiring hospitalization, later followed by gallbladder removal and a temporarily paralyzed leg.
7. He now uses a walker and scooter, is exhausted by simple tasks, and links his sudden decline to the timing of his third shot.
