From the VAERS matching of call center cases (loader/vaers_match_*). Only the best match is shown, and only if it scores 8 or more out of 11. The score adds up timing (VAERS received soon after the call center contact), dose and shared symptoms; state only breaks ties. Confidence is high when the score is 8+ and at least 3 points ahead of the runner-up, medium when 5+ and 2 ahead, otherwise low. A match is a likely link, not a confirmed one.

Each entry is dated by the survey it was written in (the CDC re-sent the releases with survey dates in 2025); click a date to see that survey response. The CDC cut some text off at about 250 characters: symptoms in every release, and the other two fields in releases 9-12. Those entries are marked "cut off by CDC".
