Biden: We Need to Go "Door to Door" to Get People Vaccinated

How Does VAERS Link Vaccine Deaths?

According to their website:

VAERS collects data on any adverse event following vaccination, be it coincidental or truly caused by a vaccine. A report to VAERS generally does not prove that the identified vaccine(s) caused the adverse event described. It only confirms that the reported event occurred sometime after vaccine was given.... Coincidences make it difficult to know whether a particular adverse event resulted from a medical condition or from a vaccination. Therefore, vaccine providers are encouraged to report all adverse events following vaccination, whether or not they believe the vaccination was the cause.

However, the VAERS website also states:

Underreporting is one of the main limitations of passive surveillance systems, including VAERS. The term 'underreporting' refers to the fact that VAERS receives reports for only a small fraction of actual adverse events.
