I think you're jumping the gun a bit here. If vaccines save 10,000 people and kill 10 people, that's still a net positive. That's the kind of moral calculus public health has to deal with all the time.
But the deepest crimes lie elsewhere, by those in power who coerced others into taking drugs they did not want, who used ends-justify-the-means reasoning to violate ethics as physicians or public health officials, and who now continue to try to suppress, deflect, and gaslight us from recognizing the real events which actually occurred and which we are morally obligated to correct for our children.
Or to put it another way, how many vaccine skeptics were pushing for the heavy use of masks, better HVAC systems in buildings, and social distancing when possible? Because I've noticed a large correlation between those that spoke out against vaccines and those that spoke out against any preventative measures at all - regardless of how benign.
It was said once that 5 deaths is a tragedy, but 500k is just a statistic (as a justification of genocide). This is possibly why the 5 deaths in the article possibly from the vaccine is apparently more terrifying.
For 1.5 years we had the notion of "1 death is 1 too many" shoved down our throats at every turn to justify some pretty heinous encroachments on personal freedom.
You need to take age into account, no?
