I don't get it, it says that they've used the data from "Vaccine Adverse Events Reporting System VAERS", and it says that "In large part, reports to VAERS are voluntary, which means they are subject to biases. This creates specific limitations on how the data can be used scientifically. Data from VAERS reports should always be interpreted with these limitations in mind."

What's the point of the system of reporting adverse events from vaccines if it's can't be used in data analysis? How do people have to report adverse effects then? How do we measure valid data?
