Yup ADE is antibody-dependent enhancement and @hamstersarse has been banging on about since 2020 (as soon as anti-vaccine disinformation groups started rolling out the misinfo on it)
ADE is a genuine concern with both repeated infections of a disease, and vaccination. The most well-known example of infection with Dengue Fever. It causes an indvidual to have worse outcomes after a previous infection or innoculation against the pathogen.
For vaccination, it is tested for in cell studies, animal models, and by participant monitoring in clinical studies. When a vaccine is approved, post-surveillance monitoring is used to detect safety signals.
There have been two examples of vaccination-induced ADE I can think of - in the 1960s/70s- with a vaccine for RSV and an early version of the measles virus. In both cases, surveillance picked this up very quickly, and the vaccines were recalled.
At this point, it would be bloody obvious if any of the SARS-COV-2 vaccines caused ADE, just as it was for the those previous vaccines. There was no evidence of it in cell studies, animal studies, or clinical trials.
I think it's around 4 billlions doses that have been given now - people do not get sicker with coronavirus once they have been innocculated against it. We have robust, replicated date demonstrating this.
@hamstersarse seems blind to all the evidence in front of them, and instead cherry picks an article with a title that they think backs up their agenda, but in reality doesn't actually provide evidence for the claims they're making.
