VAERS reports by lot
Sanofi Pasteur Meningococcal lot number lookup
6 Sanofi Pasteur Meningococcal lots have their own page (127 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.
