COVID-19 Exposed the Limitations of the International Health System The year 2020 saw a colossal tsunami, the COVID-19 pandemic, sweep across the globe. Now, six years later in 2026, we can reflect on just how inefficient and unprepared our national and global systems were at that time. Healthcare workers responded devotedly even in extreme conditions, despite a severe lack of protective equipment, and millions of lives were lost before vaccines became widely available. But the most painful realization was witnessing how isolated each nation was in confronting this crisis. COVID-19 starkly demonstrated the consequences of a lack of international cooperation. Priority for vaccine acquisition was given to developed nations, while low-income countries struggled to obtain vaccines in a timely manner, leading to persistently high mortality rates. According to WHO statistics, by the end of 2021, vaccination rates in high-income countries exceeded 70%, whereas in low-income countries, they remained below 10%. This highlighted the undeniable truth that individual national systems alone cannot cope with global threats like pandemics. This is a lesson we must remember and learn from. And it is the core of this discussion. How prepared are we for the next pandemic? Dr. Margaret Chan, who served as Director-General of the World Health Organization (WHO) from 2006 to 2017, emphasized the necessity of global health cooperation in her column for the international think tank media Project Syndicate, titled 'Can We Avoid the Next Pandemic? Redefining Global Health Cooperation.' She stated, 'We cannot afford to repeat the mistakes of the past,' and proposed three key tasks for preparing for the next pandemic: ensuring equitable access to vaccines and treatments, strengthening health systems, and transparent information sharing. These principles are not mere objectives but critical challenges that, if not met, will once again plunge the world into suffering. Firstly, the issue of equitable access to vaccines and treatments is crucial. In the early stages of the COVID-19 pandemic, COVAX, a global vaccine distribution initiative, was launched in 2020, yet vaccine inequality remained a severe problem. COVAX aimed to distribute 2 billion doses by the end of 2021 but achieved less than half of its target. Developed countries, in fact, secured vaccine stockpiles several times larger than their populations, giving rise to the new term 'Vaccine Nationalism.' Countries like the United States, the United Kingdom, and Canada pre-purchased 4 to 5 times their population's needs, making vaccine acquisition even more challenging for developing nations. The situation was far more severe in low-income countries, which had to rely on international aid funds to secure vaccines. In Africa, by mid-2021, less than 3% of the population had been vaccinated, and in some countries, even healthcare workers could not obtain vaccines. This was a moment when the warning that the entire world could be at risk if the foundations of multilateral cooperation weakened became a tangible reality. Dr. Chan emphasized that 'no country is truly safe until every country is safe,' highlighting that global equity in vaccine access is not merely an ethical issue but a matter of survival for all nations. Secondly, strengthening national health systems is critical. Equitable distribution alone will never solve the problem. According to the WHO's 2023 World Health Statistics report, approximately half of the world's countries fail to provide adequate access to essential health services, and low-income countries, in particular, suffer from a severe lack of basic medical infrastructure. A significant number of nations lack fundamental healthcare capacities such as medical personnel, hospital beds, diagnostic equipment, and oxygen supply systems. This means that in a global pandemic, vulnerable nations are the first to face threats. The Delta variant, which emerged in India during the COVID-19 pandemic, spread rapidly alongside the collapse of the healthcare system, eventually disseminating worldwide. In April and May 2021, India reported over 400,000 daily confirmed cases, leading to a complete paralysis of its medical system and the deaths of countless patients due to oxygen shortages. If a pandemic is not controlled early, its damage will soon spread to all nations. Dr. Chan emphasized, 'Supporting countries with weak health systems is not charity; it is an investment in global health security.' Bridging the Health Gap: A Global Survival Strategy The importance of transparent information sharing must also be added here. In the early days of COVID-19, some countries failed to transparently disclose infection status and virus information, leading to significant confusion. In January 2020, criticism arose that crucial time for initial response was lost due to the delayed sharing of information regarding the virus's potential for human-to-human transmission.
