Just follow the logic trail and you understand how any conversation is going to go off the rails. There’s definitions for things it’s how you get a medical diagnosis and there is one for long covid as well. It’s probably not neat and tidy which is a problem but it does exist. Say someone that was hospitalized and had their lungs absolutely wrecked by covid and now are fatigued and have difficulty breathing do they have long covid, no it’s cause is well known and defined. Does someone that gets Guillain-Barré syndrome have long covid, no they have Guillain-Barré syndrome caused by covid, just like if it was caused by CMV or EBV, and the rare case a vaccine like the flu shot or zoster vaccine. So then here’s where making up definitions creates things that are misleading.
1. The covid vaccine causes long covid
2. Long covid is just a broad term it includes things like Guillain-Barré syndrome
The covid vaccine does cause things like Guillain-Barré syndrome at an extremely low low rate, just as a slew of other vaccines do but to call it long covid is wrong at best.
Maybe we should starting calling all long term negative effects of any vaccine "Long Covid," just for simplicity.
