Vivotif side effects: where the data is
Reported reactions for Vivotif and the other typhoid products are compiled on the typhoid vaccine page: pre-licensure trial reactogenicity, VAERS report counts, and international databases (Canada Vigilance, EudraVigilance, Lareb, VigiAccess). Those counts are spontaneous reports with no denominator — a report does not establish that the vaccine caused the event.
Vivotif lot number lookup
This site does not yet hold lot-level VAERS counts for typhoid vaccines. Any lot can still be searched in the lot explorer; a lot number is printed on the vaccination record and the vial.
