"Beers for Biodefense" - why yeast-based vaccines could be a big deal for biosecurity

A scientist drank a beer brewed with genetically modified yeast and developed antibodies against a virus. This demonstrates a potential new method for creating edible vaccines in foods like beer or chips. The approach could allow rapid, low-cost distribution during outbreaks, bypassing lengthy drug approval processes. It represents over 15 years of work, initially targeting a virus that threatens immunocompromised patients like transplant recipients.
