95% of Singapore population has mRNA vaccines, but less than 0.01% report these symptoms.

Sounds exactly like a theist. Simply claim something then ask others to prove he is wrong.

From Health Science Authority of Singapore:
The serious AE reporting rates for the first and second booster doses were at 0.004% (162 reports) and 0.0005% (2 reports), respectively, which were lower compared to the primary doses at 0.009% (916 reports).

Sure, can speculate like that all you want.
But let's pretend it's unstated by 10 times, it's still less than 0.05%
