Queensland Woman's Life-Threatening Battle with Meningococcal B in Japan
Anna Gallo, a 24-year-old from Queensland, Australia, experienced a life-threatening medical emergency while traveling in Japan with her partner, Liam McDonald. Her ordeal began on February 5, when she started shivering, shaking, and vomiting, before ultimately fainting.
Rapid Deterioration and Diagnosis
As her condition worsened rapidly, her partner observed a quickly spreading rash across her body. This alarming symptom indicated the onset of septic shock. Gallo was immediately transported to Tokyo's National Center for Global Health and Medicine for urgent care.
Doctors at the facility diagnosed her with meningococcal B, which had swiftly progressed to meningitis and septic shock. She subsequently entered a three-day coma, necessitating intubation, a blood transfusion, and a regimen of intravenous antibiotics. Medical staff conveyed the gravity of the situation to her parents, who traveled from Australia, informing them that her prognosis was uncertain and there was a high risk of permanent brain damage.
Recovery and Ongoing Treatment
Miraculously, Gallo emerged from her coma on February 10, a significant step in her recovery. She was then moved from intensive care to high care as her condition stabilized.
While her brain scans have thankfully shown no permanent damage, her physical recovery continues. She is currently unable to walk due to necrotic lesions on her feet and legs, a severe complication of the septic shock. These lesions will require further specialized treatment upon her anticipated return to Australia.
Public Health Context and Vaccine Disparity
Gallo had received a meningococcal vaccination during her schooling, but importantly, it did not cover type B. This specific strain, meningococcal B, is now a key focus for public health. In Queensland, free vaccinations for meningococcal B (Bexsero) were only introduced in March 2024, after Gallo's incident.
The severity of Gallo's case underscores a broader public health concern.
Public health officials, including Mater Health Services director Paul Griffin, consistently emphasize the critical need for a consistent and comprehensive national immunization program across Australia.
The prevalence of meningococcal B also varies significantly between regions: Japan recorded fewer than five confirmed cases annually between 2003 and 2020, while Australia has reported 109 cases in 2024 alone.
