Vaxchora side effects: where the data is
Reported reactions for Vaxchora and the other cholera products are compiled on the cholera 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.
