More Powerful RNA Vaccines

MIT researchers have engineered both the nanoparticles used to deliver the COVID-19 antigen and the antigen itself, to boost the immune response, without the need for a separate adjuvant. If further developed for use in humans, this type of RNA vaccine could help to reduce costs, the dosage needed, and potentially lead to longer-lasting immunity.
