RESUMEN
Vaccine cooperation is an important means to deal with global infectious diseases. However, the cooperation cannot be achieved overnight. Ethical dilemma is one of the obstacles that hinders vaccine cooperation. Reviewing the history, the most successful vaccine collaboration to date has been the global smallpox eradication program. In the process of eradicating smallpox, there were also many ethical dilemmas, including the international pattern of the US-Soviet hegemony, which impacted the mutual help between countries, the ethical disputes of the vaccine itself hindering solidarity and cooperation among actors, and the vaccine coercion adopted to overcome vaccine hesitancy undermining the principle of proportionality among the freedom, equality and efficacy. The ethical dilemmas of vaccine cooperation were resolved by shaping professional and scientific consensus among medical professional groups, reaching consensus on cooperation between leading countries and developing countries, and integrating local culture to improve vaccination methods. Finally, in 1980, the world successfully eradicated smallpox. The case of smallpox eradication provides us lessons for vaccine cooperation against COVID-19 and the construction of a community of common health for mankind today.
RESUMEN
The concept of "virus sovereignty" proposed by Indonesia in 2007 challenges the international tradition of virus sharing. In the context of the global outbreak of coronavirus disease 2019, the issue of virus sharing has become an important topic in the reform of the global health governance mechanisms. Virus sharing is an important guarantee of dealing with major global infectious diseases. However, the emergence of the concept of "virus sovereignty" shows that there are defects in the operation of virus sharing mechanism in the international community. The "virus sovereignty" problem is an ethical issue essentially, involving asymmetric interests hindering unity and cooperation, intellectual property rights expansion challenging the principle of solidarity, and excessive self-defense amplifying utility risks. "Community of common health for mankind" provides a constructive and feasible option to solve the dilemma of "virus sovereignty".
