After RFK, Jr. is replaced: A breakthrough mRNA vaccine that suppresses food and seasonal allergies

A new mRNA vaccine stopped allergens from causing dangerous immune reactions and life-threatening inflammation in mice, according to researchers from the Perelman School of Medicine at the University of Pennsylvania and Cincinnati Children’s. The vaccine, outlined in the Journal of Clinical Investigation, may one day be tested and tailored to a variety of seasonal and food allergies.

“This is a potential breakthrough for millions of people worldwide who suffer from life-threatening allergies,” said Nobel laureate Drew Weissman, MD, PhD ….

[Scientists] tweaked the mRNA to instruct cells to produce proteins that resemble certain allergens. By presenting these proteins in a controlled way, the vaccine didn’t cause allergic reactions but did instruct the immune system to respond more appropriately in the future. And, when mice were later exposed to the respective allergens, the vaccines worked.
