native_samples You've been misinformed. We have pre launch studies with 40k+ participants showing no meaningful risk. And post launch when there were exceedingly rare ("This adverse event is rare, occurring at a rate of about 7 per 1 million vaccinated women between 18 and 49 years old. For women 50 years and older and men of all ages, this adverse event is even more rare.") and not unexpected clotting issues vaccine administration was paused so the issue could be analyzed more thoroughly and quantified specifying to defeat this kind of FUD. "As to safety The Pfizer trial reported serious adverse reactions in 0.6% of vaccine recipients and 0.5% of placebo recipients." https://www.sciencemediacentre.org/expert-reaction-to-phase-...https://www.cdc.gov/coronavirus/2019-ncov/vaccines/safety/sa...https://www.cdc.gov/vaccines/covid-19/info-by-product/pfizer...
Unfortunately, there is evidence that trials under-state risks. Evidence for this is:
1. Safety notices for the vaccines have been edited post launch to start talking about risks of heart inflammation and other problems, which were not detected by the trials but are now common enough to justify people being warned about them.
Additionally, the trials never formally completed, cannot now complete because the control groups have been vaccinated, and some of them excluded whole groups of people e.g. pregnant women, children and in some cases the elderly!
This leads to an absurd situation in which the US CDC is saying that the vaccine is safe for pregnant women simultaneous with Moderna starting trials in pregnant women (who were previously excluded).
And finally, putting all those problems to one side, the issue is actually relative risks. Even if the risk of a vaccine is low, even if similar to or higher than the risks of the thing it's trying to vaccinate you against, it may not make sense to take it. That is just basic cost/benefit analysis.

2. Drug trials appear to regularly understate the scale of side effects and nobody can figure out why: https://sebastianrushworth.com/2021/07/19/do-drug-trials-und...
