MTG cited data that's purely anecdotal and has never been verified by the FDA or any other government agency. VAERS accepts reports of adverse events from anyone but the data on it is always UNVERIFIED.
There is a Disclaimer right on their site that states in part..."VAERS reports alone cannot be used to determine if a vaccine caused or contributed to an adverse event or illness. The reports may contain information that is incomplete, inaccurate, coincidental, or unverifiable. 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."
