Summary of the Expert Hearing on the “National Decade Against Post-Infectious Diseases” in the German Bundestag
17 December 2025 | 07 Fatigatio e.V. News
On 17 December 2025, a public expert hearing on the planned “National Decade Against Post-Infectious Diseases” was held in the Committee on Research and Technology of the German Bundestag. All participating experts assessed the event as a historic opportunity to finally address conditions such as ME/CFS, Long Covid, and other post-acute infection syndromes (PAIS) in a systematic manner.
In Germany, at least 1.5 million people are affected, many of them severely ill, permanently unable to work, and so far without effective therapeutic options. For these individuals, the “National Decade Against Post-Infectious Diseases” is not merely a research project—it was described by all experts as a historic opportunity.
In preparation for the event, Fatigatio e.V. had coordinated substantively with several of the individuals involved.
A central consensus among the invited experts—including representatives from Charité Berlin, the University of Bonn, the University of Ulm, Erlangen Eye Clinic, and the ME/CFS Research Foundation—was the clear classification of post-infectious diseases as organic, biomedical multisystem disorders. They are explicitly not primarily psychosomatic conditions. Decades of psychologization have massively hindered research, diagnostics, and care, costing valuable time. Accordingly, it was demanded that the National Decade consistently focus on mechanistic research, biomarker development, improved diagnostics, and the development of effective therapies, rather than concentrating predominantly on health services research or purely observational studies.
Several experts, particularly Jörg Heydecke of the ME/CFS Research Foundation, called for a significantly higher pace and a stronger focus on solutions. In view of the enormous individual suffering and the high macroeconomic costs, further delays were deemed unacceptable. Germany must also learn from international missteps, such as large-scale cohort studies without meaningful therapeutic progress. Instead, a parallel approach was advocated: basic research, biomarker development, and clinical therapeutic research should be advanced simultaneously. Early experimental studies with smaller, well-characterized patient groups, as well as a central, coordinated study platform, were identified as crucial.
Another major focus of the hearing was the role of biomarkers. All experts emphasized the pronounced heterogeneity of post-infectious diseases and the failure of “one-size-fits-all” approaches. The key to success lies in the development and validation of biomarkers and biosignatures for clearly defined subgroups. These must be closely linked to therapeutic approaches so that changes under treatment can serve as evidence of biological relevance. The goal is to establish personalized, evidence-based treatment pathways. PD Dr. Bettina Hohberger illustrated this using the comparison with the HbA1c value in diabetes: only the linkage of biomarker and therapy enables real breakthroughs.
From a scientific perspective, early and systematic therapeutic research was also called for. This includes, in particular, the targeted repurposing of already approved drugs, the promotion of new active substances with a clear biological rationale, and the combination of drug studies with omics and biomarker analyses. Prof. Carmen Scheibenbogen reported initial therapeutic effects, for example in connection with autoantibodies or hyperbaric oxygen therapy. At the same time, she made clear that genuine interest from the pharmaceutical industry only arises once robust biological data are available. In this context, she confirmed concrete engagement by Sanofi in ME/CFS studies as well as ongoing discussions with other companies.
There was also unanimous warning that the mere establishment of structures, cohorts, and data collections is insufficient. Funding should be awarded exclusively to centers and consortia with proven expertise. To ensure quality and independence, the use of international reviewers not based in Germany was recommended. In addition, long-term, cross-disease data and research platforms are needed instead of short-lived individual projects.
Early, binding, and structural involvement of patients was highlighted as a key success factor. Patient organizations should not be involved merely symbolically but in concrete ways—for example, in steering committees, in shaping funding guidelines, in proposal evaluations, and as cooperation partners in research projects. This was regarded by all sides as a prerequisite for relevant and practice-oriented research.
At the same time, the experts identified clear shortcomings in the current approach. The funds currently earmarked for biomedical research—approximately €20 million for biomarker development and €30 million for therapeutic research over five years—were assessed as insufficient. Further demands included a consistent departure from purely psychosocial explanatory models, the nationwide transfer of successful studies into standard care, the systematic inclusion of children and adolescents, and long-term planning security beyond individual funding periods.
In the second part of the hearing, the focus increasingly shifted to political implementation. Members of parliament from various parties asked about the concrete translation of research results into therapies, about prioritization, and about political responsibility. The scientific community described a model of “paternoster research,” in which clinical observations are fed back into the laboratory and the insights gained there are then tested clinically again. Money alone is not sufficient for this; decisive leverage effects are required. Public funding must be designed in such a way that it attracts the pharmaceutical industry while remaining clearly clinically and scientifically led. In particular, early Phase II studies cannot be carried out by universities without state support.
The issue of patient involvement was also discussed in a differentiated manner. There was broad agreement that patient organizations are indispensable, but that their involvement must be clearly structured. Not every initiative brings the same level of medical-scientific expertise. Politics should therefore distinguish between political advocacy and technical collaboration and selectively involve those organizations that can make a substantive contribution to research. At the same time, patient representatives signaled their willingness to professionalize and their desire for clearly defined participation formats.
In response to questions about realistic next research steps, the experts made clear that Germany already has identified biomarkers and biosignatures. The next essential step is smaller, well-designed Phase II therapeutic trials with approximately 50 to 100 patients in clearly defined subgroups. Large, unselected cohorts are not required for this. What is currently lacking above all are funding, suitable study infrastructure, and sufficiently qualified personnel.
Another point of discussion was the distinction between Post-Vac, Long Covid, and ME/CFS. While Post-Vac, according to Dr. Hohberger, must be regarded as a separate entity and investigated scientifically, Prof. Schultze assessed that Post-Vac syndrome is not a post-infectious disease and therefore does not belong in the National Decade. At the same time, Prof. Scheibenbogen made it clear that Long Covid and ME/CFS already occurred in identical form before vaccines were available. Large studies also show that vaccinations reduce the risk of Long Covid by around 50 percent, and that boosters further reduce this risk. Long Covid is not a vaccine complication.
Regarding questions about risk groups, it was explained that women in particular, as well as people with a genetic predisposition, carry an increased risk. Genetic studies such as DecodeME point to the involvement of genes from the fields of immunology, neurology, and mitochondrial function. Certain pre-existing conditions can also increase the risk.
Several members of parliament specifically asked about possible long-term consequences of COVID-19 for the brain. Prof. Schultze referred to indications of structural brain changes as well as neurovascular and immunological damage. Historical parallels, such as the Spanish flu, suggest delayed waves of dementia following pandemics. International studies indicate that a proportion of dementia cases could be post-infectiously triggered. At the same time, vaccinations—for example against herpes zoster—show a reduction in dementia risk, which points to viral involvement. While there is no automatism, the risk is increased and the need for research correspondingly urgent.
Finally, the role of the pharmaceutical industry was addressed. Prof. Scheibenbogen explained that the industry had held back for decades due to a lack of biological clarity and medical consensus. The National Decade now sends a strong political signal. Concrete effects are already visible, including the engagement of Sanofi and further ongoing discussions. Targeted dialogue formats between politics, science, and industry were proposed.
All of these contributions result in a clear political mandate for action. Policymakers are called upon to explicitly prioritize biomedical research, define clear funding criteria, ensure international peer review, promote translation in a binding manner, actively enable cooperation with the pharmaceutical industry, structurally involve patient representatives, and consider the care perspective from the outset.
The overall conclusion of the event was unequivocal: the scientific evidence is more advanced than is often assumed. Those affected are not waiting for new insights, but for their implementation. Germany has excellent researchers, initial therapeutic approaches, and growing international interest. What has been lacking so far are political clarity, sufficient and purposefully deployed resources, and binding structures. The “National Decade Against Post-Infectious Diseases” was described by all experts as a historic opportunity. Whether it will indeed become a turning point depends decisively on whether policymakers, scientists, patients, and industry now act consistently, in a coordinated manner, and with a focus on solutions.
