Janssen (J&J) COVID-19 lot 211A21A: VAERS reports

460 VAERS reports list lot 211A21A as a Janssen (J&J) COVID-19 vaccine, received between 2021-09-21 and 2024-09-23. Data: VAERS public files through 31 December 2024 (site extract 2026-07-04).

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.
