## Sample Essay 1: Mandatory Vaccination Policies

Question: Some countries have made vaccination mandatory for all children before they can attend school, while others allow parents to choose whether to vaccinate their children. Discuss both approaches and give your opinion.

Band 9 Sample Answer

Contemporary vaccination policy debates reflect fundamental tensions between public health imperatives and individual autonomy principles, with mandatory immunization requirements representing one of the most contentious intersections of governmental authority and parental rights. While proponents of compulsory vaccination emphasize collective protection benefits and scientific evidence, advocates for parental choice prioritize individual freedom and diverse philosophical perspectives on medical interventions.

Mandatory vaccination policies derive their justification from compelling epidemiological evidence demonstrating that high immunization coverage rates provide community-wide protection through herd immunity mechanisms that safeguard vulnerable populations unable to receive vaccines due to medical contraindications. Countries implementing comprehensive school-entry requirements have consistently achieved superior disease prevention outcomes, virtually eliminating vaccine-preventable diseases such as measles, mumps, and rubella that previously caused substantial childhood morbidity and mortality. Furthermore, mandatory programs ensure equitable access to immunization benefits across socioeconomic strata, preventing disparities that could emerge if vaccination decisions depended solely upon parental knowledge, resources, or healthcare access. The economic arguments for compulsory immunization are equally compelling, as prevention costs represent a fraction of treatment expenses for vaccine-preventable diseases, while avoiding productivity losses associated with illness-related school and work absences.

However, advocates for voluntary vaccination approaches raise legitimate concerns regarding bodily autonomy, religious freedom, and the precedent of governmental authority over individual medical decisions. Parental rights to make healthcare choices for their children represent fundamental principles in democratic societies, with mandatory vaccination policies potentially conflicting with diverse cultural, religious, or philosophical beliefs about medical interventions. Moreover, while serious adverse events from vaccines remain extremely rare, some parents express concerns about individual risk-benefit calculations that may differ from population-level assessments, particularly for children with specific health conditions or family histories. The coercive nature of school-entry requirements effectively eliminates educational access for non-vaccinated children, raising equity concerns about penalizing families for exercising conscientious objection rights.

In my assessment, mandatory vaccination policies with limited, clearly defined exemptions represent the most ethically defensible approach to balancing individual autonomy with collective welfare. The overwhelming scientific evidence supporting vaccine safety and effectiveness, combined with the demonstrated public health benefits of high coverage rates, justifies reasonable limitations on individual choice when such choices could harm vulnerable community members.

However, successful mandatory programs must incorporate robust exemption processes for legitimate medical contraindications, comprehensive public education initiatives that address parental concerns through transparent communication, and accessible healthcare systems that eliminate barriers to vaccine access. The goal should be achieving voluntary compliance through evidence-based persuasion while maintaining policy frameworks that protect community health when individual decisions might compromise collective welfare.

## Sample Essay 2: Vaccine Development and Distribution

Question: The development of COVID-19 vaccines happened much faster than usual vaccine development. Some people believe this rapid development compromised safety, while others argue it demonstrated scientific advancement and international cooperation. Discuss both views and give your opinion.

Band 9 Sample Answer

The unprecedented speed of COVID-19 vaccine development and global distribution has sparked considerable debate regarding the relationship between scientific acceleration and safety assurance, reflecting broader questions about innovation under emergency conditions and public trust in pharmaceutical research. While skeptics express concerns about compressed development timelines potentially compromising rigorous safety protocols, advocates emphasize revolutionary scientific achievements enabled by international collaboration and advanced research methodologies.

Critics of accelerated vaccine development argue that traditional immunization research timelines exist precisely because comprehensive safety evaluation requires extended observation periods to identify rare adverse events and long-term effects that may not manifest during abbreviated clinical trials. The typical decade-long vaccine development process incorporates multiple phases of increasingly large-scale human testing, regulatory review periods, and post-market surveillance systems designed to detect uncommon complications that could affect vulnerable populations. Furthermore, the unprecedented global pressure for rapid vaccine deployment potentially created institutional incentives that prioritized speed over thoroughness, with regulatory agencies facing political and economic pressures that might have influenced approval decisions. Public health authorities' emphasis on vaccination benefits while minimizing discussion of potential risks may have inadvertently undermined informed consent principles and public trust in healthcare institutions.

However, proponents of the accelerated development process contend that COVID-19 vaccine creation represented a triumph of modern scientific capabilities, international cooperation, and resource allocation rather than a compromise of safety standards. The compressed timeline resulted primarily from parallel rather than sequential development phases, with unprecedented financial investment enabling simultaneous research activities that typically occur consecutively due to resource limitations. Moreover, mRNA vaccine technology had been under development for decades, with COVID-19 applications building upon established research foundations rather than entirely novel approaches. The global nature of the pandemic provided unprecedented opportunities for large-scale clinical trials with diverse populations, potentially generating more comprehensive safety data than traditional studies with smaller, more homogeneous participant groups.

In my view, the COVID-19 vaccine development process demonstrated both remarkable scientific achievement and the importance of transparent communication about uncertainty and evolving evidence. While the speed of development was genuinely unprecedented, the fundamental safety protocols remained intact, with compressed timelines resulting from resource availability and parallel processing rather than eliminated safety measures.

Future vaccine development should maintain the innovative collaboration and resource allocation approaches demonstrated during the pandemic while incorporating lessons learned about public communication, informed consent processes, and the importance of acknowledging uncertainty in scientific communication to maintain public trust in health authorities and evidence-based medicine.

## Sample Essay 3: Global Vaccination Equity

Question: Wealthy countries purchased most of the world's COVID-19 vaccines, leaving poorer nations with limited access. Some argue this was natural market behavior, while others believe it represents a moral failure. Discuss both perspectives and give your opinion.

Band 9 Sample Answer

The global distribution of COVID-19 vaccines has exposed profound inequalities in healthcare access, with wealthy nations securing disproportionate vaccine supplies while lower-income countries faced severe shortages, raising fundamental questions about market-based resource allocation versus ethical obligations for equitable healthcare access during international health emergencies. This disparity reflects broader debates about national sovereignty, international cooperation, and moral responsibility in global health governance.

Defenders of market-based vaccine distribution argue that wealthy nations' procurement strategies represented legitimate exercises of national sovereignty and fiscal responsibility, with governments using available resources to protect their populations through advance purchase agreements that provided essential funding for vaccine development. These early investments enabled pharmaceutical companies to scale production capacity and accelerate research timelines, ultimately benefiting global vaccine availability through market-driven innovation. Furthermore, national governments possess primary obligations to their citizens, with international assistance representing supplementary rather than mandatory responsibilities. The market-based approach incentivized rapid vaccine development through guaranteed purchase commitments, creating competitive pressures that accelerated innovation and production efficiency. Without such market incentives, vaccine development might have proceeded more slowly, potentially resulting in prolonged global pandemic conditions that would have harmed all nations.

However, critics of vaccine nationalism argue that pandemic response requires coordinated international action, as infectious diseases transcend national boundaries and global health security depends upon universal access to protective measures. The concentration of vaccines in wealthy countries while healthcare workers in developing nations remained unprotected represents a profound moral failure that undermined global solidarity and perpetuated health inequalities rooted in economic disparities rather than medical need. Moreover, epidemiological evidence demonstrates that incomplete global vaccination coverage enables continued viral mutation and transmission, potentially generating variants that could evade existing vaccine protection and threaten previously protected populations. The hoarding of vaccines by wealthy nations not only violated principles of global justice but also represented strategically counterproductive policies that prolonged pandemic conditions through sustained international transmission chains.

In my assessment, the global vaccine distribution patterns during COVID-19 revealed fundamental inadequacies in international health governance systems that prioritize national wealth over global health security and ethical obligation. While national governments do bear primary responsibilities to their citizens, pandemic response requires recognition that infectious diseases create shared vulnerabilities requiring coordinated responses.

Future pandemic preparedness should incorporate international frameworks that ensure equitable vaccine access through advance purchase commitments for global distribution, technology transfer requirements, and international production capacity development that prevents wealthy nations from monopolizing limited medical countermeasures during health emergencies when global cooperation becomes essential for effective response.
