Argentine vaccine deal probe: Sigman denies irregularities, seeks dismissal

Pharma executive Hugo Sigman submitted a written statement to Judge Ariel Lijo, denying any irregularities in Covid-19 vaccine agreements with AstraZeneca and Sinopharm under the Fernández government, and distancing his companies from dose marketing. The case continues, with Sigman requesting dismissal. This is a legal development in an ongoing corruption investigation, not a market-moving event.
