Vaccinations can be a controversial subject for many people, especially when it comes to injections. So what if you could replace your next shot with a salad instead? Researchers at the University of California-Riverside are working on a way to grow edible plants that carry the same medication as an mRNA vaccine.

The COVID-19 vaccine is one of the many inoculations which use messenger RNA (mRNA) technology to defeat viruses. They work by teaching cells from the immune system to recognize and attack a certain infectious disease. Unfortunately, mRNA vaccines have to stay in cold storage until use or they lose stability. The UC-Riverside team says if they're successful, the public could eat plant-based mRNA vaccines — which could also survive at room temperature.
