Macrophagic Myofasciitis, or MMF, is a rare muscle disease identified in 1993. The disease is characterized by microscopic lesions found in muscle biopsies that show infiltration of muscle tissue by PAS-positive macrophages.[1] Specific causes of MMF are unknown. Intramuscular injections of aluminium-containing vaccines have been implicated.[1] Many of those affected with the disease had previously been treated for malaria with chloroquine or hydroxychloroquine.[2]

Clinical symptoms include muscle pain, joint pain, muscle weakness, fatigue, fever, and muscle tenderness. A diagnosis can only be identified with an open muscle biopsy of the vaccinated muscle.[3]

Studies at the University of Paris have shown that MMF lesions result when the aluminum hydroxide adjuvant from a vaccine remains embedded in the tissue and causes a steady immune reaction. [4][5][6][7]

As of 1999, MMF had only been observed in France.
