Messenger RNA (mRNA) vaccines hold promise for creating new and improved immunizations; however, their delivery is challenging in terms of compliance, reactogenicity, cost and scalability. In response to ‘the ultimate bioengineering challenge’ competition, we propose an edible mRNA vaccine platform using lettuce chloroplasts.
