MIT develops stronger RNA vaccine for Covid-19 with enhanced delivery.

Researchers at MIT have developed a new RNA vaccine for Covid-19 that produces a stronger immune response at a lower dose. The team engineered the nanoparticles used to deliver the vaccine and the antigen itself to boost the immune response, eliminating the need for a separate adjuvant. The vaccine also showed promise when delivered intranasally, potentially offering enhanced protection against infection and making it easier to administer.
