The article you quote is one of the rare ones that allow comments. As usual, the comments are a great way to gauge the truthfulness and understand the article's bias. This one shows the author's obvious bias;
How on earth did you not know that one of your co-authors was associated with Rational Ground, which has a definite ax to grind when it comes to COVID-19 and COVID-19 vaccines, being dedicated to opposing most COVID-19 public health mitigation measures as unnecessary, and also made up of people with zero expertise relevant to COVID-19, epidemiology, VAERS, you know, the sort of knowledge needed for the sort of study you did? To me, that admission is just incredible, in that it strains credulity. At the very least, it suggests a serious lack of due diligence about whom you choose as a co-author. No, you can't say there was no "relationship whatsoever to Rational Ground." You just can't! One of your co-authors is a founder of Rational Ground, and THAT in and of itself is a relationship, whether you like it or not.- D.G.
You are right the VAERS database has not been validated for accuracy. Anyone can report a potential VAERS complication. We shouldn't just ignore the 14,506 covid vaccine deaths, 58,440 covid vaccine hospitalizations, or 675,591 covid vaccine adverse event reports, just because somebody made a report that has errors or is otherwise less than perfect. These reports should be investigated, not ignored. This is more important in light of the Lazarus Report that estimated that VAERS only captures 1% of vaccine injuries.
