We were talking about COVID-19, and your own source states that
Evidence of ADE has not emerged for COVID-19 vaccines even though concerns have been raised.
As @Mythfortune mentioned, the few vaccines that were found to cause ADE were withdrawn from the market. Fortunately,
Neither COVID-19 disease nor the new COVID-19 vaccines have shown evidence of causing ADE. People infected with SARS-CoV-2, the virus that causes COVID-19, have not been likely to develop ADE upon repeat exposure. This is true of other coronaviruses as well. Likewise, studies of vaccines in the laboratory with animals or in the clinical trials in people have not found evidence of ADE.
While it’s true that vaccines can cause ADE, there’s no evidence that any vaccines that are currently being produced (including COVID vaccines) do so.
Again, from your own source:
early during the COVID-19 pandemic, concerns about ADE were top of mind. During this time, a few scientists tried to predict whether ADE would occur by evaluating genes for similarities and differences. While this was a useful approach at a time when we did not have much information about what might happen in people, we have since accumulated several lines of clinical evidence that confirm ADE is not an issue for COVID-19 or the vaccines …
Unfortunately, some people continue to spread misinformation suggesting that ADE is an ongoing concern for COVID-19 vaccines; however, scientists and clinicians are continuing to monitor COVID-19 infections and, to date, no evidence to validate this concern has emerged.
