ME/CFS is a long-lasting illness of extreme fatigue and other symptoms that often starts suddenly like a flu. This review examines several theories about what might cause ME/CFS, including infections, genetic factors, hormone problems, immune system dysfunction, and psychological stress. The authors discuss a newer condition called ASIA syndrome, which involves autoimmune reactions that may be triggered by vaccine adjuvants (ingredients added to vaccines to boost immune response).
This review is important because it consolidates multiple etiologic theories for ME/CFS and highlights the emerging ASIA syndrome concept, which may help explain why some patients develop ME/CFS-like symptoms following infections or immunological triggers. Understanding potential mechanisms—whether infectious, genetic, immune-mediated, or adjuvant-related—is crucial for guiding future diagnostic and therapeutic research.
This review does not prove that vaccines or adjuvants cause ME/CFS, nor does it establish a definitive causal mechanism for the disease. It presents hypotheses and theoretical connections rather than new empirical evidence, and correlation between infectious illness onset and ME/CFS symptoms does not establish infection as the primary cause. The speculative nature of ASIA syndrome links to CFS requires rigorous prospective studies to validate.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
