Transverse myelitis (TM) is a neurological condition that is caused by inflammation of the spinal cord. When the spinal cord becomes inflamed, the insulation barrier around the nerve cells (called myelin) begins to break down. As a result, the communications between the spinal cord nerves and the rest of the body may be interrupted or delayed, resulting in numbness or paralysis throughout the body. Transverse myelitis can be triggered by a viral or bacterial infection, but some suspect that it could also develop as a reaction to a vaccine. The development of transverse myelitis after vaccination is relatively rare, but it has been associated with many different vaccines commonly administered to adults, infants, and children. The most likely vaccines to provoke reactions include inoculation against flu, measles-mumps-rubella (MMR), tetanus-diphtheria-pertussis (TDaP), and the hepatitis B virus.
