VAERS reports by lot
Protein Sciences (Sanofi) Flu lot number lookup
17 Protein Sciences (Sanofi) Flu lots have their own page (484 VAERS reports in total).
Read this first. VAERS accepts reports from anyone, and a report does not establish that the vaccine caused the event. A lot's report count mostly reflects how many doses it contained, when it was used and who received it; no administered-dose counts are published for this lot, so counts are not rates and cannot rank lots against each other. Lot numbers in VAERS reports are typed by reporters and are sometimes wrong.
