The Daily Expose.uk, is a go-to site for technical objections to the Covid vaxxes, a bit more detail than other great sites like Natural News.com. A recent article puts the case that the risk of stroke due to the Covid jab increases by a whopping 11,361 percent, compared to seasonal flu shots. I imagine that the pro-vaxxers would argue that the risk of stroke from the seasonal flu shot is relatively low, so the argument is deflected. But still, the mainstream Covid vax narrative has held that stroke risk is just as low as the seasonal flu shot, so the claims are significant.
