A Universal Influenza Vaccine Are Being Developed By MIT Researchers

Scientists at MIT and the Ragon Institute of MIT, Massachusetts General Hospital, and Harvard have recently announced that they have been working on strategies for designing a universal flu vaccine that could work against any flu strain.

The vaccine is made up of nano-particles coated with flu proteins that train the immune system to create the desired antibodies. In a clinical study, it was shown that the vaccine induces an antibody response targeting that elusive protein segment when tested in mice with humanized immune systems.

The research team is excited about this new milestone as they are a step forward in developing a flu vaccine that provides immunizations against any seasonal flu strains.
