Waning immunity
Antibody kinetics, B-cell memory, T-cell persistence and the biological factors associated with changing protection over time.
Singapore · July 12–14, 2027
Vaccine durability and waning immunity conference.
NULLIFY 2027 brings together the scientific, clinical, regulatory and public-health perspectives required to understand why protection fades—and how the next generation of vaccines can be designed, evaluated and deployed for more durable immunity.
The central question
How do we build protection that holds?
Vaccine performance is not defined only by the initial immune response. The duration, quality and breadth of protection influence booster schedules, product differentiation, public confidence, health-system planning and the real-world impact of immunization programmes.
NULLIFY creates a focused environment for examining durability across immune memory, antigen and platform design, clinical endpoints, surveillance, regulation and implementation. It is a conference for people who need to connect mechanistic science with practical vaccine-development decisions.
Scientific and strategic themes
What the vaccine durability programme explores.
Correlates of protection
How immune markers, clinical endpoints and real-world evidence can support predictions about durability and effectiveness.
Next-generation platforms
Approaches to antigen design, adjuvants, delivery systems and platform engineering intended to improve the quality or persistence of immunity.
Clinical development
Trial design, longitudinal follow-up, population differences and evidence strategies for measuring durable protection.
Regulation and policy
How regulators, public-health agencies and developers evaluate changing effectiveness, booster strategies and post-market evidence.
Implementation
Translating durability evidence into immunization schedules, procurement decisions, communication and equitable access.

What is a vaccine durability conference?
A vaccine durability conference examines why protection changes over time and how immune memory, antigen design, delivery, clinical evidence, surveillance and booster strategy can support longer-lasting protection.
What topics does NULLIFY 2027 cover?
NULLIFY covers waning immunity, antibody and T-cell persistence, immune memory, correlates of protection, next-generation platforms, clinical development, regulatory evidence and public-health implementation.
Who should attend NULLIFY 2027?
The summit is intended for immunologists, vaccine developers, clinicians, regulators, public-health leaders, academic researchers, technology partners and organizations developing or evaluating vaccines.
