Jabbed Pilots a Danger in the Sky

Something that was on people's radars about a year or so ago but you do not hear much about recently. Pilots that have been jabbed appear to be at higher risk of heart attacks in the cockpit. Apparently in response the FAA has reduced the coronary testing requirement for commercial pilots, including the ones that fly passenger jets. This is a disaster waiting to happen. I have heard stories of one pilot dying or becoming incapacitated while in flight. The copilot had to take over and land the plane. This means the plane has fallen to its backup plan. What if the backup plan fails? The backup plan is taking the same shots.
