As U.S. cases rise, a nationally representative panel survey by the Annenberg Public Policy Center finds a small but significant drop in the proportion of the public that would recommend that someone in their household get the MMR vaccine, which protects against measles, mumps, and rubella. The survey finds drops in both the perceived safety and effectiveness of the MMR vaccine as well as two other vaccines.

A research team at the Nano Life Science Institute (WPI-NanoLSI) and the Faculty of Medicine at Kanazawa University has developed a new class of engineered extracellular vesicles (EVs) capable of inducing antigen-specific regulatory T cells (Tregs), the immune cells that play a central role in suppressing excessive immune responses. The findings, now published in Drug Delivery, may pave the way for next-generation therapies for autoimmune and allergic diseases, where unwanted immune activation must be precisely controlled.
