In their recent article, Akkad et al1 describe a case of transverse myelitis (TM) in a 27-year-old woman 4 days after vaccination with monovalent A (H1N1) live, attenuated influenza vaccine. The authors state that, “Extensive diagnostic evaluation effectively ruled out causes other than vaccination-associated TM.” However, the report of this event to the US Vaccine Adverse Event Reporting System (VAERS ID 373104) states the patient reported treatment for mycoplasma pneumonia 20 days before symptom onset.
