Anti-COVID Nanobubbles Block the Virus from Infecting Cells

Vaccines aren’t the best at protecting against virus variants because they focus on a specific strain. According to a recent Medgadget article, a team of researchers at Northwestern University has a new strategy to fight the virus that is unlikely to be affected by changes in future variants. They discovered natural extracellular vesicles in the blood that act as a decoy binding site for viral particles and prevent them from binding to and infecting cells.
