Why This Summit
Despite growing clinical and immunological evidence, there are no agreed diagnostic criteria, no validated biomarkers, and no completed randomized controlled trials for Post-Acute Vaccination Syndrome (PACVS). The International PACVS Research Summit is the first expert working meeting dedicated to closing these gaps through rigorous, consensus-based methods.
Three Outputs
Consensus Statement
A co-authored, peer-reviewed paper establishing the first proposed diagnostic criteria and research priorities for PACVS.
Core Biomarker Panel
Expert consensus on candidate biomarkers for diagnosis, prognosis, and treatment monitoring in PACVS.
Research Network
An international working group of scientists, clinicians, and patient research partners committed to advancing PACVS research.
Our Approach
We use a modified Delphi consensus method — the same approach used by WHO to define Long COVID — combined with a structured virtual workshop. All panelists rate statements anonymously, discuss contested items in facilitated breakout groups, and finalize positions through iterative voting. The result is a transparent, reproducible consensus that meets peer-review standards.
