GCC health leaders urge action to close meningitis B protection gap in high-risk adults
Sharper surveillance, electronic risk flags, and clear policy accountability around meningococcal disease required to ensure high-risk patients are vaccinated across the region.

An engineer with sickle cell disease arrived at an Abu Dhabi hospital in late December confused, septic and deteriorating by the hour. Within weeks, he had lost both legs, an arm and several fingers. Seven weeks later, he remained ventilated in intensive care.
This incident was presented as a case study during a closed-door roundtable session at World Health Expo (WHX) that assessed meningococcal B risk in high-risk adult populations in the GCC. Prominent healthcare leaders pointed at the urgent need to raise awareness about the infection and build a public policy framework for vaccination.
Invasive meningococcal disease (IMD) is rare, but clinically unforgiving.
Even with prompt treatment, it kills an estimated 10% to 15% of patients. Up to one in five survivors is left with permanent disability, which may include hearing loss, neurological impairment, skin necrosis, or limb amputation. Its progression can be brutally fast with flu-like symptoms spiralling into septic shock within 24 hours.
Notably, the Gulf region is not experiencing sustained large-scale outbreaks. But health officials present at the roundtable argued that structural realities, featuring dense urban settings, highly mobile expatriate populations, clusters of labour accommodation and mass communal gatherings, create conditions for silent transmission. Meningococci can colonise the nasopharynx without symptoms, spreading through coughing, sneezing or prolonged close contact. Carriage rates are widely estimated at 10% to 20% in the general population, rising in crowded settings.
According to the World Health Organization, asymptomatic carriage is well recognised in public health and estimates commonly place it around 10 to 20% at any given time, rising in crowding or epidemic settings.
Therefore, in highly connected cities such as Dubai, where its international airport handled more than 92 million passengers in 2024 and welcomed nearly 19 million international overnight visitors, the epidemiological equation is shaped as much by mobility as by incidence.
High-risk adults, uneven protection
The roundtable focused squarely on high-risk adult populations, where policy gaps are the most visible.
Those without a functioning spleen, including many patients with sickle cell disease, face significantly elevated risk, alongside individuals with complement deficiencies, those receiving complement-inhibiting therapies, transplant recipients, certain oncology patients, people living with HIV, laboratory workers and others that are repeatedly exposed to crowded environments.
The risk gradient can be extreme. Persistent complement deficiencies may increase susceptibility by several thousand-fold, while complement inhibitor therapies have been associated with dramatically higher incidence compared with the general population.
Yet while childhood immunisation programmes across the GCC are typically well-structured and high-performing, adult vaccination is more fragmented. Policy frameworks may exist, but implementation often relies on clinician discretion rather than embedded system triggers. Guidance, according to several leaders at the WHX-exclusive roundtable, “sits on paper” without enforcement mechanisms.
Moreover, it is the post-pandemic vaccine scepticism that has compounded the challenge. Policymakers now navigate not only debates around cost-effectiveness, but also growing hesitancy among the public as well as increased concerns from healthcare workers themselves.
Lessons and warning signals from communal gatherings
Saudi Arabia’s meningococcal control strategy that evolved from meningitis A was cited as an example of how policy can reshape epidemiology. Following major outbreaks including W135 in the late 1990s and early 2000s, the Kingdom introduced mandatory quadrivalent (MenACWY) vaccination for Hajj pilgrims, backed by strict certification requirements. Compliance has been enforced through visa-linked checks.
The approach is widely credited with preventing recurrence of large Hajj-associated outbreaks.
However, Umrah, which attracts tens of millions of pilgrims annually as access has expanded, does not operate under identical enforcement mechanisms. The scale of travel has raised concerns about vaccination compliance, particularly as international public health agencies have reported travel-associated IMD cases linked to pilgrims and returning travellers in recent years. Public health agencies outside Saudi Arabia have also documented travel-associated IMD linked to Umrah.
In May 2024, European and US reporting flagged clusters of invasive meningococcal disease in travellers (and close contacts) returning from Saudi Arabia, with many cases serogroup W and many unvaccinated. A WHO outbreak notice later underscored that travel-associated cases continued to be reported into 2025, alongside concern about declining vaccination compliance for Umrah.
Even though the focus of the roundtable was meningococcal B risk in high-risk adults, health experts equivocally agreed that in an interconnected region, gaps in one jurisdiction carry implications for all. This is why the sharing of health data among the GCC countries could lay a solid foundation to combat the spread of disease and ensure guardrails for its prevention.
Public health responsibility or individual choice?
Financing and accountability are key aspects when discussing and debating on public health. One of the healthcare experts highlighted that in several Gulf states, blue-collar expatriate workers are insured under basic health packages that may not cover adult vaccines. Policymakers often seek local burden data before committing public funds, particularly for diseases with relatively low incidence.
Others at the table, however, argued that severity, not frequency alone, should guide policy. When a disease can kill or permanently disable within hours, they contended, vaccination cannot be treated as an optional, individual consumer choice.
Bahrain’s primary care model was cited as an illustration of how system design can influence outcomes.
Under its “Choose your doctor” programme, citizens are assigned a named family physician, and preventive care indicators are embedded within performance metrics. Participants suggested that similar key performance indicators (KPIs) tied to vaccination in immunocompromised adults could help shift uptake.
Digitisation as the structural lever
If one theme united the discussion, it was digitisation.
Electronic medical record systems, participants argued, should do more than store data. They should actively prompt action. Embedding automated risk flags for high-risk conditions, with mandatory acknowledgement or override documentation, could shift vaccination from passive recommendation to active clinical workflow.
Some healthcare systems in the region already deploy pop-up reminders and recall mechanisms for older adults and defined risk groups. But coverage is uneven, and surveillance systems do not always capture serogroup data consistently across borders.
Stronger laboratory capacity, routine serogroup identification programmes and real-time GCC data-sharing were identified as critical next steps.
Without granular surveillance, policymakers remain caught between acting on international evidence and waiting for local numbers to justify investment.
On the ethical question of whether to wait for more region-specific data or to act now to protect clearly identifiable high-risk adults, the prevailing sentiment was unequivocal. Delay, in meningococcal disease, can be measured not in years, but in hours.
