Researchers at the University of Pennsylvania and Cincinnati Children’s have developed an mRNA vaccine that prevented dangerous allergic reactions in mice, potentially revolutionizing treatment for food and seasonal allergies. The University NetworkA pioneering mRNA vaccine has successfully prevented dangerous allergic reactions and life-threatening inflammation in mice, a breakthrough that could revolutionize the treatment of food and seasonal allergies. The new vaccine leverages the mRNA lipid nanoparticle (LNP) technology used in COVID-19 vaccines but is modified to instruct cells to produce proteins resembling specific allergens. “People with food allergies that can cause anaphylactic shock are rightfully fearful in social situations, eating out in public, sharing food, and engaging in other fun activities where there are food and allergens around,” Weissman added. “We saw mRNA vaccines save lives during the pandemic, and as the most-tested type of vaccine in history, we know it’s the safest and most effective vaccine ever created,” added Weissman.
