IOW, even the VAERS information is probably not accurate because sometimes things either aren't reported by physicians, or they might be double reported from various sources, etc.  So these sites are constantly monitored now, so that doesn't happen and so their information is much more accurate.  No one had considered that the VAERS information may not be totally accurate.  But it's a whole helluva lot closer to reality than anything you're going to get from some GUBMINT system of "reporting" (even more skewed, but always in favor of the gubmint, of that you can be positive).
