The epidemiological contrast between Pakistan and the United States starkly illustrates the impact of comprehensive prevention strategies. Globally, cervical cancer caused approximately 530,000 new cases and 250,000 deaths in 2020, with 85% of this burden concentrated in low- and middle-income countries (LMICs) [10]. Pakistan exemplifies this disparity. According to GLOBOCAN 2024, Pakistan records 2722 new cervical cancer cases and 1640 deaths annually, with an ASR (World) of 3.0 per 100,000 women and a 5-year prevalence of 6642 cases. Notably, cervical cancer does not rank among the top five female malignancies in Pakistan by incidence; breast cancer (43,721 cases) leads, followed by corpus uteri, ovary, colorectum, and lip/oral cavity cancers [2]. The Karachi Cancer Registry has documented ASIRs of 6.81 (1995-1997), 7.47 (1998-2002), and 6.02 (2017-2019) per 100,000 women, indicating a longstanding burden that the more recent GLOBOCAN estimates may reflect in aggregate at the national level [11]. HPV prevalence in Pakistan is substantial. A study analyzing invasive cervical cancer specimens found HPV-DNA prevalence of 87.5%, with high-risk genotypes HPV-16 and HPV-18 responsible for nearly 90% of cases [12]. Among tested women in Karachi, HPV prevalence was 16.7% [7]. Alarmingly, 94.81% of cervical cancer lesion biopsies in Punjab tested positive for HPV [13]. Current HPV vaccines could theoretically prevent 78.4% of invasive cervical cancer cases in Pakistan.

In stark contrast, the United States has achieved remarkable success in cervical cancer prevention. Following widespread HPV vaccination implementation, HPV infections declined by 88% in females aged 14 - 19 years and 81% in those aged 20 - 24 years [5]. Organized screening programs and high vaccination coverage have reduced cervical cancer incidence and mortality by nearly 75% over the past 50 years in high-income countries [14]. The median standardized incidence in ultra-high Human Development Index (HDI) countries is 7.3 per 100,000, while in low-HDI countries it is nearly three times higher [10].

The mortality disparity is equally striking. Globally, cervical cancer caused 270,000 deaths in 2015, with 90% occurring in LMICs. The incidence is 15.7 cases per 100,000 women in LMICs versus 9.9 in high-income countries, and cervical cancer is 18 times more morbid in LMICs [15]. Pakistan is projected to experience 129,184 cervical cancer deaths between 2020 and 2070 if current trends continue [13].

During the MGH observership, it was observed how systematic prevention, through routine HPV vaccination of adolescents, catch-up vaccination for young adults, and organized screening programs, has transformed cervical cancer from a common malignancy into an increasingly rare disease in the United States. This transformation is not merely a function of wealth; it reflects deliberate, evidence-based public health strategies that Pakistan must urgently adopt and adapt.

2.2.1. Socio-Cultural Barriers

Socio-cultural factors constitute perhaps the most formidable barrier to HPV vaccination in Pakistan. The association of HPV with sexual transmission creates profound discomfort in a conservative society where discussions about sexual health are deeply taboo [16][17]. These taboos lead to widespread ignorance about sexually transmitted diseases and cervical cancer prevention. A qualitative study in Karachi found that adolescent girls were unfamiliar with basic female reproductive health concepts, and parental vaccine hesitancy, particularly among fathers who serve as primary decision-makers, was a significant barrier [18].

The stigma surrounding HPV vaccination is multifaceted. It employed an intersectional lens to analyze how mistrust, stigma, and inequity rooted in historical, gendered, religious, and geopolitical power dynamics hinder vaccine acceptance. Moral anxieties surrounding adolescent sexuality create resistance, with many parents fearing that vaccination might encourage sexual activity [9]. This concern is not unique to Pakistan but is amplified by conservative cultural norms.

Gender dynamics further complicate vaccine acceptance. A study in Karachi revealed striking gender bias: 88% of women responded negatively regarding vaccine acceptability for their sons, compared to 37% for their daughters [19]. This disparity reflects deeply ingrained beliefs about gender, sexuality, and vulnerability. Additionally, fathers are identified as key decision-makers for vaccination, while female relatives are preferred for health discussions, creating a communication gap that impedes informed decision-making [18].

Cultural hesitation extends beyond individual families to community-level resistance. In the principal author’s practice in a peripheral Pakistani city, families have been encountered who view HPV vaccination with suspicion, sometimes influenced by rumors spread through social media about alleged side effects, including infertility claims. The Tando Bago incident, where mass psychogenic reactions occurred following vaccination, exemplifies how cultural anxieties can rapidly escalate into public health crises [8].

2.2.2. Religious Concerns and Misconceptions

Religious misconceptions represent another critical barrier. While Islam does not prohibit vaccination, diverse religious interpretations and lack of clear endorsement from religious leaders create hesitancy [9]. Some community members mistakenly believe that HPV vaccination conflicts with Islamic teachings, particularly regarding premarital sexual activity [13]. These misconceptions are often amplified by misinformation circulating on social media platforms [20].

Interestingly, comparative insights from the United Arab Emirates and Saudi Arabia, both Muslim-majority countries with higher vaccination acceptance challenge assumptions about inherent religious resistance [9]. This suggests that the barrier is not Islam itself but rather the absence of culturally sensitive health communication that addresses religious concerns within an Islamic framework. During the MGH observership, it was noted how providers are trained to address vaccine hesitancy by acknowledging patients’ values and beliefs while providing evidence-based information, an approach that could be adapted for Pakistan by engaging Islamic scholars and community leaders.

2.2.3. Knowledge and Awareness Gaps

Knowledge and awareness gaps are pervasive across all segments of Pakistani society. Multiple studies document alarmingly low awareness of HPV, cervical cancer, and the preventive vaccine. Only 20.6% of women in Karachi were aware of HPV as a risk factor for cervical cancer, and merely 25.5% knew a preventative vaccine existed [13]. Among female undergraduate students in Karachi, 69.9% were aware of the HPV vaccine, but only 19.3% were vaccinated [21]. Another study found that 36.09% of young female students had no prior knowledge of HPV vaccines [16].

Even among healthcare providers, knowledge gaps are concerning. A study of female healthcare providers at a public sector hospital aimed to assess knowledge, attitudes, and vaccination frequency, revealing significant deficiencies [22]. Another study of physicians in a teaching hospital in Karachi highlighted that successful vaccination programs require primary care physician recommendations, yet many physicians lack adequate knowledge to provide strong recommendations [23].

The lack of information is consistently cited as the primary reason for non-vaccination. In one study, 58.8% of women reported lack of knowledge as the main barrier [17], while another found that 58% cited lack of information [24]. This knowledge deficit extends beyond awareness of the vaccine’s existence to understanding its mechanism, safety profile, and importance for cancer prevention. Only 40.2% of women in one Karachi study were familiar with HPV vaccination’s ability to prevent cervical cancer [17].

In the principal author’s clinical practice, even educated women have been observed to confuse HPV with HIV or remain unaware that HPV is sexually transmitted. This fundamental knowledge gap makes it nearly impossible for women to appreciate the vaccine’s value. During the MGH observership, the routine integration of HPV education into adolescent well-visits was particularly striking, with providers using age-appropriate language and visual aids to explain the vaccine’s cancer-prevention benefits, a practice virtually absent in most Pakistani healthcare settings.

2.2.4. Structural and Infrastructural Barriers

Structural and infrastructural deficiencies pose formidable challenges to HPV vaccination in Pakistan. Until the September 2025 launch of the national campaign, HPV vaccination was not included in any national immunization program [1]. The vaccine remains unavailable in most regions, and where available, it is prohibitively expensive [25]. Nearly half of respondents in one study perceived the vaccine as overpriced (46.8%) [26], and only 12% of women were willing to pay for vaccination themselves [19]. Even among those willing to accept vaccination, 49% would only do so if it were free [17].

Rural healthcare infrastructure is particularly inadequate. Pakistan’s peripheral cities and rural areas lack the cold chain logistics necessary for vaccine storage and distribution [13]. Healthcare facilities are often understaffed and under-resourced, making it difficult to add new vaccination programs. The recent nationwide campaign has been disrupted by natural calamities, including floods, which have damaged infrastructure and displaced populations [8].

The cost-intensive nature of HPV vaccination for large-scale populations, given Pakistan’s limited health budget, creates a significant barrier. While international organizations like Gavi, the Vaccine Alliance, have provided support for the 2025 campaign [8], sustained funding and infrastructure development are essential for long-term success. The vaccine delivery model, whether clinic-based, school-based, or community-based, requires careful planning and resources that are currently insufficient.

In contrast, during the MGH observership, a robust infrastructure was witnessed where vaccines are readily available, cold chain is meticulously maintained, and multiple delivery points, including primary care clinics, specialty clinics, pharmacies, and mobile vaccination units, ensure accessibility. This infrastructure is supported by substantial public health funding and insurance coverage that eliminates cost barriers for patients.

2.2.5. Healthcare System Barriers

Healthcare system barriers compound the challenges of vaccine delivery. Inadequate training of healthcare professionals is a critical issue [13]. Many physicians and nurses lack confidence in discussing HPV vaccination, addressing parental concerns, or providing strong recommendations. Studies have shown that physician recommendation is a powerful predictor of vaccine acceptance, yet many Pakistani healthcare providers do not routinely recommend the vaccine [21].

The absence of systematic reminder systems and electronic health record prompts means that vaccination opportunities are frequently missed. Unlike the U.S. system, where EHR alerts notify providers when patients are due for HPV vaccination, Pakistani healthcare settings rely on paper records or fragmented electronic systems that do not support population health management. This lack of systematization results in inconsistent vaccine delivery.

Healthcare provider attitudes also play a role. Some providers view HPV vaccination as unacceptable or unnecessary, reflecting their own knowledge gaps and cultural biases [17]. The perception that vaccination is time-consuming (41.8% of respondents) further discourages providers from prioritizing it in busy clinical settings [26].

The healthcare system’s focus on curative rather than preventive care is another barrier. In the principal author’s experience practicing in Pakistan, preventive services are often deprioritized in favor of treating acute illnesses. There is little institutional incentive or accountability for vaccination coverage, unlike in U.S. academic centers, where quality metrics and pay-for-performance models incentivize preventive care.

2.2.6. Gender and Access Barriers

Gender-related barriers are deeply intertwined with socio-cultural factors but merit separate attention. Women in Pakistan face multiple access barriers, including limited autonomy in healthcare decision-making, restricted mobility, and economic dependence [9]. In many families, women require permission from male relatives to seek healthcare, creating delays and missed opportunities for vaccination.

Socioeconomic disparities exacerbate these barriers. Women from lower socioeconomic backgrounds have less access to health information, are less likely to attend schools where vaccination campaigns might occur and face greater financial constraints [9]. The presumption among some women that they do not need the vaccine “right now” reflects both lack of urgency and limited understanding of the vaccine’s preventive nature [17].

Geographic disparities also affect access. Urban women, particularly those in major cities like Karachi and Lahore, have better access to healthcare facilities and information compared to women in rural and peripheral areas. However, even in urban settings, women from marginalized communities face barriers. The intersectionality of gender, socioeconomic status, geography, and education creates compounded disadvantages that must be addressed through targeted interventions.

One of the most striking features of HPV vaccination programs in U.S. academic cancer centers is the emphasis on provider education and communication training. At MGH and similar institutions, providers receive structured training on how to deliver strong, presumptive recommendations for HPV vaccination. A study described a locally adapted quality improvement program involving physician training facilitated by local physicians with high HPV vaccination rates [27]. This training included didactic instruction and video vignettes modeling effective communication techniques.

The communication approach emphasizes a “presumptive” rather than “participatory” style, where providers announce the vaccine as part of routine care rather than asking if parents are interested [27]. This subtle shift in framing significantly increases acceptance rates. Providers are also trained to address common concerns about vaccine safety, efficacy, and necessity using evidence-based talking points.

A provider-level intervention used Intervention Mapping to strengthen provider recommendations in a Federally Qualified Health Center [28]. The intervention included didactic instruction, interactive role-play with tailored messages, and take-home materials such as fact sheets and clinical guidelines. This comprehensive approach ensures that providers are not only knowledgeable but also confident and skilled in vaccine communication.

During the MGH observership, gynecologic oncologists were observed routinely recommending HPV vaccination to eligible patients during visits for HPV-related dysplasia or cancer, recognizing these as teachable moments [29]. This practice extends cancer prevention beyond the primary care setting into specialty care, maximizing opportunities for vaccination.

Electronic health record (EHR) systems are central to HPV vaccination success in U.S. academic centers. EHR-based alerts and reminders ensure that no eligible patient is overlooked. The 4 Pillars™ Program, which includes documenting vaccination in the electronic medical record, reviewing and updating accurate records, and using EHR prompts to alert providers when patients are due for vaccination [30].

One study implemented a multicomponent, systems-based intervention at a sexual and reproductive health clinic that included electronic health record prompts, in-clinic education, and scheduling of the next visit at the current visit [31]. This approach significantly increased catch-up HPV vaccination rates. Similarly, U.S. healthcare settings utilized EHR systems for vaccination reports and gave provider prompts as part of quality improvement interventions [32].

The integration of immunization registries with EHR systems allows for population-level tracking of vaccination coverage and identification of patients who are overdue for vaccination. While EHR and immunization registry data are used to monitor rates, interoperability issues and staffing needs can limit effective implementation, highlighting ongoing challenges even in well-resourced settings [33].

At MGH, EHR alerts were observed to appear automatically when a patient’s chart is opened, prompting providers to discuss HPV vaccination if the patient is eligible. This systematization removes the burden of remembering from individual providers and ensures consistent vaccine delivery across the institution.

Patient navigation and multidisciplinary approaches are hallmarks of U.S. academic cancer centers’ vaccination programs. Patient navigators help address barriers to vaccination by providing education, scheduling appointments, arranging transportation, and following up with patients who miss appointments. This personalized support is particularly valuable for underserved populations.

Multidisciplinary teams involving physicians, nurses, pharmacists, community health workers, and quality improvement specialists collaborate to design and implement vaccination programs. A study described how the University of Texas MD Anderson Cancer Center, an NCI-designated cancer center, developed an institutional framework to increase adolescent HPV vaccination by assembling a transdisciplinary team and constructing a portfolio of collaborative multi-sector initiatives [34]. This resulted in an implementation community of 78 institutions collaboratively implementing 12 initiatives within a shared measurement framework.

Mobile vaccination programs extend access beyond traditional clinical settings. It was evaluated by an HPV Vaccination Van Program established by the Medical University of South Carolina Hollings Cancer Center, which provided mobile HPV vaccinations in school districts and health clinics, and focused on children aged 9 - 18 [35]. The program emphasized a vaccine-bundling approach, offering all recommended adolescent vaccines, and involved partnerships with school districts and community organizations.

A multilevel pilot intervention guided by evidence-based approaches and community input, involving parents, primary care teams, and clinics, increased HPV vaccination among rural adolescents aged 11 - 17. This multilevel approach significantly increased both initiation and completion rates [36].

During the MGH observership, the seamless coordination between different departments and the availability of patient navigators who ensure that vulnerable patients do not fall through the cracks were particularly impressive. This level of coordination and support is largely absent in Pakistani healthcare settings.

Quality improvement (QI) initiatives are systematically employed in U.S. academic centers to continuously enhance HPV vaccination rates. These initiatives involve setting measurable goals, tracking progress, providing staff feedback, and implementing iterative improvements based on data.

Quality improvement leaders in healthcare systems endorsed HPV vaccination as beneficial, with facilitators for implementing HPV vaccine QI programs including automation and standardization in QI efforts and passionate vaccine champions [37]. Almost all QI leaders reported future plans to implement HPV vaccine QI projects.

The 4 Pillars™ Program described includes tracking progress, setting goals, and providing staff feedback as core quality improvement components. A study used weekly audits to track data and identify eligible students for vaccination in a university student health clinic, demonstrating how regular monitoring drives improvement [38].

A study implemented a quality improvement initiative involving counseling and offering HPV vaccination to eligible postpartum patients aged 26 years or younger [39]. Physicians were surveyed to assess clinician-reported patient screening for HPV vaccine eligibility, which significantly increased during the initiative.

At MGH, quality metrics for HPV vaccination are regularly reviewed at departmental meetings, and providers receive feedback on their vaccination rates compared to institutional benchmarks. This culture of continuous improvement, supported by data transparency and accountability, drives sustained high performance.
