South America's 2023 Flu Vaccines Cut Risk of Flu Hospitalizations by About Half

RNA vaccines against Covid-19 have proven effective at reducing the severity of disease. However, a team of researchers at MIT is working on making them 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.Adjuvants are molecules commonly used to increase the immu
