Medical misinformation in Poland has become in 2025 a much larger ecosystem than the old anti-vaccination narratives. A NASK report, conducted within the Central European Digital Media Observatory, CEDMO, shows that false or manipulative messages targeted schools, vaccines, cancer, medical screening, abortion, transfusions, transplants, unnecessary therapy, and the credibility of public institutions.
Misinformation also targeted infectious diseases such as tuberculosis, whooping cough, diphtheria, and influenza. In the case of whooping cough, the report shows that messages accused the media of manipulating epidemic data and claimed that vaccines would be ineffective. In some cases, the increase in the number of infections was attributed to migrants or Ukrainian refugees, which can intensify xenophobic attitudes and polarize public debate….One narrative claims that a treatment for cancer exists but is hidden for commercial reasons….
Another risky area concerns pseudomedical therapies. The report mentions the promotion of drugs or substances such as ivermectin, hydroxychloroquine, propranolol, vitamin D3, vitamin C, vitamin B17, melatonin, graviola, horseradish, stevia, honey, red clover, sweet wormwood, green walnut husk, dandelion, and apricot seeds. Some posts presented cancer as a metabolic disease, recommended a ketogenic diet or “alkalizing” the body, while others described tumors as encapsulated parasites.
