This doesnt make sense on its face. That means that your immune system would always be a ticking time bomb for any infection -> this does not happen.
Not for any infection — specific to the coronavirus antigens. Many papers out there; manufacturers of vaccine are trying to minimize the probability by excluding certain adjuvants and other bio components known to exacerbate this. If the vaccine works so well there is no illness or little illness that’s great. But ADE is a known possibility and affected all or nearly all lab animals in a particular study when exposed to a significantly mutated cv.

“Data from the study of SARS-CoV and other respiratory viruses suggest that anti-SARS-CoV-2 antibodies could exacerbate COVID-19 through antibody-dependent enhancement (ADE).”
