Such a rewarding collab it has been with our colleagues at #Novavax to dissect the MoA of their potent Matrix-M adjuvant. This project has really put the imaging skills of @erixoneriksson.bsky.social to the test. The fruits of this joint labour out now in NPJ Vaccines

Despite its fishy name, the bacteria salmonella has no connection to the underwater creature.
