Vaccine designs that elicit a robust immune response against a pathogen without causing unneeded inflammation are in high demand. To ‘tune’ vaccines and achieve this balance, the adjuvant and its mode of delivery are critical. In a paper by Robert Seder and colleagues, the authors explore the use of different types of polymers to deliver Toll-like receptor agonists, a type of powerful adjuvant, and find that polymer-adjuvants best suited for vaccine design are those that form particles. The paper also examines factors that influence why some polymers work better than others.
