Vietnam has seen an increase in cases of IMD, especially among adolescents who have a high rate of bacterial carriers but display no symptoms. The vaccination suggestions made by the Vietnam Association of Preventive Medicine are for two high-risk groups for invasive meningococcal disease: children under five years old and adolescents.
IMD is uncommon but very serious. Without prompt treatment, the mortality rate can reach approximately 50 per cent, and in some cases, death may occur within 24 hours of symptom onset. Even with timely medical intervention, around 20 per cent of IMD survivors face serious long-term sequelae and possible permanent disability.
Pham Quang Thai, deputy head of the Department of Infectious Disease Control at the National Institute of Hygiene and Epidemiology, said, “IMD remains a global public health burden. Survivors often suffer lifelong complications that significantly impact their quality of life, and also impact the wellbeing of family members who care for them. Based on the data from the Infectious Disease Surveillance Software according to Circular No.54/2015/TT-BYT, from July 2016 to September 2025, meningococcal disease is increasing significantly. From the beginning of the year to September 15, Vietnam recorded 38 cases of meningococcal infection, of which the north recorded an increase of 45 per cent and the south recorded an increase of 83 per cent cases compared to the year 2024.”
