The aim of the symposium is to review recent developments in the use of mRNA as a delivery platform for vaccines and therapeutics. The meeting will cover technical improvements of the platform, ongoing applications, mechanistic insights, and provide an outlook of future possibilities.
Organizers/Scientific committee
Karin Loré, Robert Seder and Gunilla Karlsson Hedestam
The symposium is sponsored by the Journal of Internal Medicine (JIM) and the Royal Swedish Academy of Sciences.
Registration
Delegates travelling to Stockholm for the 20th Key Symposium on mRNA vaccines are expected to arrange and pay for their own travel and hotel reservations. Lunch and coffee during the symposium will be covered for all delegates. Registration is on a ”first-come first-served basis”.
