Cervical cancer
The exceedingly low uptake of high-risk human papillomavirus (HPV) vaccine constitutes a critical gap in Pakistan's public health strategy. Cervical cancer, primarily caused by HPV infections, is one of the most preventable yet deadly cancers affecting women globally. According to the International Agency for Research on Cancer (IARC), cervical cancer is the fourth most common cancer among women, with 604,000 new cases and 342,000 deaths reported worldwide in 2020.
In contrast, many Western nations have made impressive strides in combating this disease. Data from Australia's National HPV Vaccination Programme show that robust vaccination efforts have led to a reduction of over 70% in HPV infections among vaccinated cohorts. These countries have embraced the WHO guidelines, which recommend routine HPV vaccination for girls aged 9 to 14 years. Specifically, the WHO advises a two-dose schedule for those vaccinated before their 15th birthday and a three-dose schedule for older recipients. Furthermore, the vaccine is over 90% effective in preventing infections with HPV types 16 and 18 — the strains responsible for nearly 70% of cervical cancer cases.
Regrettably, Pakistan lags significantly behind, with HPV vaccination coverage estimated to be below 5%. Local estimates further suggest an age-standardised incidence rate for cervical cancer ranging between 6.0 and 10.0 per 100,000 women, although these figures are likely underreported due to limited screening programmes.
Policymakers, health authorities and community leaders must integrate HPV vaccination into our national immunisation programme. Through improved vaccine coverage and comprehensive public education, we can significantly reduce the future burden of cervical cancer and safeguard the health of our women.

WHO maintains mpox alert amid West Africa surge
GENEVA: The World Health Organisation said Monday that the mpox virus epidemic remains an international health emergency with more than 37,000 confirmed cases reported since it erupted. WHO director general Tedros Adhanom Ghebreyesus announced the extension of the emergency following a meeting of international experts who noted progress in some countries but also highlighted a surge in west Africa and the spread of the virus outside Africa. The WHO said since the epidemic started in early 2024 in Democratic Republic of Congo, there have been more than 37,000 cases in 25 countries, including 125 deaths. Mpox: health dept for ensuring strict screening steps at Karachi airport DR Congo accounts for 60 percent of the confirmed cases and 40 percent of the deaths from the virus, that causes a rash and severe flu-like symptoms. Uganda and Burundi have been the next worst hit, followed by Sierra Leone, which the WHO said has seen a surge in cases this year. WHO first declared mpox an international emergency in August last year. The International Health Regulations emergency committee met last Thursday to discuss the epidemic. It decided that the epidemic remains an international emergency "based on the continuing rise in the number of cases, including a recent increase in West Africa, and likely ongoing undetected transmission in some countries beyond the African continent." It said some countries were still struggling to monitor the epidemic and with a lack of funding for treatment there was a need for "continued international support".

Pakistan's vaccine independence: a national imperative
Pakistan stands at a critical crossroads in public health policy. With seven million births annually and a population growth rate of 2.55%, our nation faces an unprecedented challenge in vaccine security that demands immediate and decisive action. The looming withdrawal of GAVI support by 2031 presents not just a crisis, but an opportunity to transform Pakistan into a self-reliant pharmaceutical powerhouse. The stark reality we face The numbers paint a sobering picture of our current vulnerability. Pakistan's complete dependency on donated and discounted vaccine supplies, supported by GAVI, UNICEF, and WHO to the tune of PKR 26 billion annually, masks a deeper structural weakness. When GAVI's support ends in 2031, the financial burden will balloon to PKR 100 billion annually as nearly four times our current federal health budget of PKR 27 billion. This dependency is not merely financial; it represents a fundamental threat to national health security. This isn't just underdevelopment—it's a systematic surrender of national health autonomy. Today, Pakistan produces virtually no antigens for the Expanded Programme on Immunization (EPI) vaccines domestically. We lack essential seed banks, have minimal university-based vaccine development programs, and operate with regulatory guidelines that are inadequate for sophisticated vaccine manufacturing. Our clinical trial expertise remains severely limited, creating bottlenecks in bringing locally developed vaccines to market. The contrast with global pharmaceutical leaders is stark. While universities worldwide have been the birthplace of revolutionary vaccines-from the Hepatitis B vaccine developed at UC San Francisco to the Oxford-AstraZeneca Covid-19 vaccine-Pakistan's academic institutions remain largely disconnected from commercial vaccine production. Learning from global success stories International experience offers valuable lessons. India transformed itself into the 'pharmacy of the world' through strategic government support for generic manufacturing and robust regulatory frameworks. Singapore built a biomedical hub through integrated research, manufacturing, and regulatory excellence that attracted billions in global pharmaceutical investment. South Korea's government-industry partnerships created world-class biopharmaceutical capabilities. These success stories share common elements: sustained government commitment, strategic investment in infrastructure, regulatory excellence, and comprehensive talent development programs. Most importantly, they demonstrate that with the right approach, developing nations can achieve pharmaceutical self-sufficiency and even become global exporters. The Triple Helix solution The path forward requires unprecedented coordination between government, academia, and industry -what experts call the 'Triple Helix' approach. Each sector must play a distinct yet interconnected role in building national vaccine capacity. Government leadership is essential in creating policy frameworks that incentivize domestic production while providing funding for university research. Strategic assignments to national research institutions like the National Institute of Health, Centre of Excellence in Molecular Biology (CEMB), National Institute for Biotechnology and Genetic Engineering (NIBGE), International Centre for Chemical and Biological sciences (ICCBS), Karachi University, Department of Biotechnology, Dow University of Health Sciences (DUHS), etc., can accelerate vaccine development and establish crucial seed banks. Most critically, the government must develop a comprehensive national health security strategy that positions vaccine self-sufficiency as a matter of national defense. The regulatory transformation cannot be understated. Pakistan's Drug Regulatory Authority must achieve WHO Level 3 qualification and create 'regulatory sandboxes — collaborative environments where university researchers, industry partners, and regulatory experts jointly develop guidelines for the 13 critical EPI vaccine antigens. Fast-track approval pathways and clear regulatory roadmaps will accelerate the journey from laboratory research to commercial production. Formation of sandboxes by bringing together leaders of the University, Regulatory and Industry. Universities must step up as innovation engines. Institutions with BSL-III laboratories should lead development of live attenuated vaccines, while biotechnology departments focus on recombinant vaccine technologies. Specialized vaccine research centers, industry-relevant curricula, and technology transfer offices will bridge the gap between academic discovery and commercial application. State-of-the-art pilot manufacturing facilities will provide proof-of-concept capabilities essential for scaling innovations. Industry brings manufacturing excellence and market expertise to the equation. Private sector partners can transform academic research into GMP-compliant commercial production, establish robust supply chains for raw materials, and navigate complex regulatory approvals. Their distribution networks and market access capabilities will ensure that domestically produced vaccines reach every corner of Pakistan. Leading companies in Pakistan already in the field of Biopharmaceutical manufacturing must be involved in the development process. A realistic implementation roadmap Success requires a phased approach spanning six years. The foundation phase (Years 1-2) must establish policy frameworks and coordination mechanisms while launching capacity-building programmes. Infrastructure development (Years 2-4) involves scaling laboratory manufacturing capabilities, establishing vaccine testing facilities, and launching pilot production programs. The scale-up phase (Years 4-6) transitions to commercial production of EPI vaccines, regulatory approvals, and distribution network establishment. Finally, the optimization phase (Year 6+) expands manufacturing capabilities, develops advanced biologics production, and positions Pakistan as a regional pharmaceutical hub. Financial innovation will be crucial. Blended financing models combining public funding, private investment, and support from institutions like the Islamic Development Bank can mobilise the substantial capital required for drug substance manufacturing facilities. The initial investment may be significant, but the long-term savings and export potential far outweigh the costs. The economic and strategic imperative The benefits extend far beyond health security. A robust domestic vaccine industry could create over 5,000 jobs and reduce import dependency by 50 percent. More importantly, it would establish Pakistan as a regional pharmaceutical hub with significant export potential to neighboring countries and the broader Islamic world. The Covid-19 pandemic demonstrated the critical importance of pharmaceutical self-reliance. Nations with domestic production capabilities could respond rapidly to their populations' needs, while others waited months for external supplies. This lesson cannot be ignored as we face an uncertain global health landscape. The time for action is now Pakistan's demographic dividend — with 65 percent of the population under 30 — represents an unprecedented opportunity to build a knowledge-based pharmaceutical sector. However, this window will not remain open indefinitely. The GAVI deadline of 2031 provides a clear timeline for action, but preparation must begin immediately. The success of this transformation depends on political will, sustained investment, and most importantly, recognition that vaccine self-sufficiency is not a luxury but a national security imperative. Countries that fail to develop domestic pharmaceutical capabilities will remain perpetually vulnerable to supply disruptions, price volatility, and foreign policy pressures. A call to national action The establishment of National and Provincial Coordination Committees bringing together leaders from academia, industry, and regulatory agencies represents the essential first step. This must be followed by a comprehensive assessment of current capabilities, development of a detailed national vaccine strategy, and launch of pilot programmes for immediate impact. Pakistan has the intellectual capital, institutional foundation and market potential to achieve vaccine independence. What we need now is the collective will to transform this potential into reality. The health and prosperity of future generations depend on the decisions we make today. The choice is clear: remain dependent on the goodwill of international donors or invest in building a self-reliant pharmaceutical sector that serves not only Pakistan's needs but positions the nation as a leader in global health innovation. The Triple Helix approach offers a proven pathway to pharmaceutical independence-we must have the courage to take it. Copyright Business Recorder, 2025

Qatar urged to upgrade Pakistani surgeons
ISLAMABAD: Pakistan has requested Qatar government to upgrade Pakistani surgeons from category three to category one enabling them to bypass appearing in tests. The request was formerly forwarded by the Federal Minister National Health Services and Regulations Syed Mustafa Kamal's recent visit to Qatar where he met with Qatar' s Health Minister Mansoor bin Ibrahim. The Qatari government assured the minister to seriously consider the request which is a longstanding demand of Pakistani doctors. Meanwhile, Kamal on Tuesday chaired a high level review meeting on polio eradication which was attended by key stakeholders, including the Prime Minister's Focal Person for Polio Eradication, Ayesha Raza Farooq, the Special Secretary Health, Additional Secretary Health, the National Polio Coordinator, as well as representatives from WHO, UNICEF, and provincial health authorities. During the meeting, a comprehensive review of the recent nationwide polio vaccination drive was presented. Over 45 million children were successfully administered the polio vaccine drops. National and provincial coordinators shared detailed updates on the ongoing polio eradication efforts, highlighting progress as well as obstacles. Kamal emphasized that protecting children from polio is a collective national responsibility that requires urgent and sustained efforts from all segments of society. He urged parents to proactively seek out polio workers and ensure the immunization of their children, reminding that safeguarding children's health is a matter of accountability both in this life and the hereafter. The Minister highlighted that while cancer treatment is possible, polio remains an incurable disease, reinforcing the critical need to eliminate the virus through effective vaccination campaigns. He called for a significant policy shift to enhance campaign effectiveness and stressed the importance of unity and societal participation in this national mission. "Only two countries in the world still face the threat of polio," Mustafa Kamal stated, noting ongoing extensive campaigns in Afghanistan, effectively supported by the Taliban government. He expressed his hope for simultaneous polio-free status for both Pakistan and Afghanistan. He concluded by motivating the nation to overcome this challenge, stating, 'If we can defeat India as one nation, we can certainly defeat polio. If Palestine remains polio-free despite war, then what are we waiting for?' The Federal Health Ministry reaffirmed its commitment to intensifying polio eradication efforts to ensure a polio-free Pakistan in the near future. Copyright Business Recorder, 2025
