I have always thought that the trope: "Long Covid" was just a cover to hide the negative and severe effects of Covid 19 "vaccinations"
They had to have a trojan horse narrative to deflect and divert unwanted attention to any long-term vax side effects: hence Long Covid
Now, I think they are laying the groundwork to blame the incoming aggressive cancers and soft tissue cancers on, you guessed it: Long Covid
