The Electronic Support for Public Health (ESP:VAERS) project, funded by HHS and conducted by Harvard Pilgrim Health Care, found 35,570 possible adverse reactions from 1.4 million vaccine doses (2.6% rate). The project summary stated 'fewer than 1% of vaccine adverse events are reported' to VAERS. The team developed an automated electronic reporting system to fix underreporting, but reported that the CDC stopped cooperating. Despite VAERS being the primary safety monitoring system, its known limitations have never been addressed.
