Why did Andreas Vesalius ideas make little impact?

Andreas Vesalius's ideas initially made little impact due to the strong adherence to traditional medical teachings, particularly those of Galen, which dominated the academic landscape. His emphasis on human dissection and direct observation challenged long-standing beliefs, but many physicians were resistant to change. Additionally, the lack of widespread access to his work and limited dissemination of his findings hampered their acceptance. Ultimately, it took time for his revolutionary ideas to gain traction, paving the way for modern anatomy.
