Primrose Bio was proud to be part of World Vaccine Congress Washington, March 30–April 2, 2026. We were pleased to engage across the program:
Our partner, Serum Institute of India Pvt. Ltd., was represented by Rakesh Lothe, who presented on multivalent conjugate vaccine development and the critical role of carrier protein manufacturing strategies.
Diane Retallack, PhD, led a working group on unmet needs in carrier proteins and presented a poster on emerging capabilities — including extracellular secretion and non-canonical amino acid incorporation — supporting conjugate vaccine discovery and development.
Andrew Burch, Louis J. Cantolupo, and Jennifer Wittbold were on hand at booth 343 to connect with attendees navigating challenges in carrier proteins or mRNA IVT performance, and to discuss how protein expression limitations may be impacting their path to scale.
