Vaccine allocation (2)

 An ethical framework for global vaccine allocation

Ezequiel Emanuel et al. article:

Fairly distributing a COVID-19 vaccine among countries is a problem of distributive justice. Although governments will be the initial recipients of vaccine, fair distribution across countries must reflect a moral concern for the ultimate recipients: individuals. Three values are particularly relevant: benefiting people and limiting harm, prioritizing the disadvantaged, and equal moral concern.

Benefiting people and limiting harm is widely recognized as important across ethical theories. Realizing this value requires defining relevant benefits, measuring them, and assessing the relative urgency—the importance and time sensitivity—of countries’ needs. A successful vaccine produces direct benefits by protecting people against death and morbidity caused by infection. It also produces indirect benefits by reducing death and morbidity arising from health systems overstressed by the pandemic, and by reducing poverty and social hardship such as closed schools.

Prioritizing the disadvantaged is a fundamental value in ethics and global health (10, 11). Realizing this value requires that vaccine distribution reflect special concern for people who are disadvantaged. Fairly distributing a COVID-19 vaccine internationally therefore requires assessing different types of disadvantage. Are the worst-off countries those experiencing the greatest poverty? Those where people have the lowest life expectancies?

Equal moral concern requires treating similar individuals similarly and not discriminating on the basis of morally irrelevant differences, such as sex, race, and religion. Distributing different quantities of vaccine to different countries is not discriminatory if it effectively benefits people while prioritizing the disadvantaged.

And the allocation model: 

 The Fair Priority Model proceeds in three phases, preventing more urgent harms earlier (see the Table). Phase 1 aims at reducing premature deaths and other irreversible direct and indirect health impacts. Phase 2 continues to address enduring health harms but additionally aims at reducing serious economic and social deprivations such as the closure of nonessential businesses and schools. Restoring these activities will lower unemployment, reduce poverty, and improve health. Finally, phase 3 aims at reducing community transmission, which in turn reduces spread among countries and permits the restoration of prepandemic freedoms and economic and social activities.

Vaccine allocation

 Discussion Draft of the Preliminary Framework for Equitable Allocation of COVID-19 Vaccine


Guiding Principles from Allocation Frameworks Developed for the COVID-19 Pandemic:

• Ensure that allocation maximizes benefit to patients, mitigates inequities and disparities, and adheres to ethical principles.

• Promote the common good through fairness, transparency, accountability, and trustworthiness.

• Save the greatest number of lives possible—while respecting rights and fairness—to

maximize benefit to the community as a whole.

• Use the best available evidence to assess benefit to communities and address uncertainty.

• Allocate scarce resources responsibly to reduce risk while providing benefit.

• Provide clear and transparent criteria for prioritization strategies.

• Ensure that allocation policies are flexible, responsive to the concerns of the affected

population, and proportionate to the epidemiological situation and the vaccine supply relative to need.

How to proceed in practical terms? Who knows...

 The Optimal Allocation of Covid-19 Vaccines

Covid-19 vaccine prioritization is key if the initial supply of the vaccine is limited. A consensus is emerging to first prioritize populations facing a high risk of severe illness in high-exposure occupations. The challenge is assigning priorities next among high-risk populations in low-exposure occupations and those that are young and healthy but work in high-exposure occupations. We estimate occupation-based infection risks and use age-based infection fatality rates in a model to assign priorities over populations with different occupations and ages. Among others, we find that 50-year-old food-processing workers and 60-year-old financial advisors are equally prioritized. Our model suggests a vaccine distribution that emphasizes age-based mortality risk more than occupation-based exposure risk.

Today we can confirm that the probability of such proposal is low. After reading FT, WHO framework has suffered a setback.
