MIT Engineers Design More Powerful Covid-19 RNA Vaccines; New Approach Could Lead to Intranasal Vaccines for Covid-19 and Other Respiratory Diseases

Nucleic acid (NA) vaccines against Covid-19 have proven effective at reducing the severity of disease. However, a team of researchers at MIT is working on making these vaccines even better. By tweaking the design of the vaccines, the researchers showed that they could generate Covid-19 RNA vaccines that produce a stronger immune response, at a lower dose, in mice.
