COVID Vaccine Safety Investigation

I haven't been as up to date on the concerns about the vaccine as others, but this statement caught my eye. Is this another case of:
1) that's a conspiracy theory and it's not happening
2) if it is happening - the numbers are small
3) it it is happening, which it isn't, it might be a good thing
4) it is happening, but this has been known and reported for a long time

My report details how in March 2021, Peter Marks — director of the FDA center that approves vaccines and is responsible for safety surveillance (CBER) — was briefed that the algorithm they were using to analyze the Vaccine Adverse Event Reporting System (VAERS) would mask or hide COVID-19 vaccine adverse event safety signals. Twenty-six days later, using an updated algorithm, senior FDA officials were shown 25 safety signals, including sudden cardiac death, pulmonary infarction, cerebral artery occlusion, basal ganglia stroke, agonal rhythm, and Bell’s palsy.
