The Vaccine Adverse Event Reporting System (VAERS) is a national vaccine safety surveillance program co-sponsored by the Centers for Disease Control (CDC) and the Food and Drug Administration (FDA). VAERS is a post-marketing safety surveillance program, collecting information about vaccine reactions (adverse events) that occur after the administration of vaccines licensed for use in the United States. Because it is post-marketing and voluntary, there are limitations to its usefulness.
I have been following the VAERS data for nearly ten years, downloading the published government data and posting it at MedAlerts.org so that anyone can examine the data for themselves. Recently, I have been examining the data more closely, making observations, describing trends, and writing this blog. The reader should know this very important fact about the blog:
I am not a medical professional.
Rather, I am a computer scientist with over forty years experience. So where I am well qualified to deal with data, I do not claim to be an expert on the medicine behind the numbers.
Blog entries are posted when a new month of VAERS data becomes available. So, for example, the June entry does not appear in June, but instead appears when all of the VAERS data for June has been released by the government (typically in July or even August). Each blog entry describes data that is current at that time, but since VAERS data is always subject to change, the actual results in an entry may not be reproducible at a later time unless you use the Wayback Machine to search the older data.
