Researchers shed light on why Covid-19 vaccine distribution methods fall short

Several proposals have emerged on how to distribute the Covid-19 vaccine, but they fall short in ensuring that the vaccine is distributed fairly.

Several proposals have emerged on how to distribute the Covid-19 vaccine, but they fall short in ensuring that the vaccine is distributed fairly. A team of researchers suggests three ways to more fairly and effectively distribute the vaccine so that people in poor countries get the vaccine as soon as possible.

The results of the study by a team of researchers from Binghamton University. was led by professor Nicole Hassoun. The paper, "Just Allocation of Covid-19 Vaccines," was published in BMJ Global Health.

"Although many people in rich countries will receive a vaccine for Covid-19 this year, many people in poor countries will likely have to wait years to get one," said Hassoun.

"Ethical vaccine allocation requires closing this gap and ensuring that everyone can access a vaccine as soon as possible. We should increase vaccine manufacturing, distribution and uptake. Rich countries should not get to prioritize their populations first."

Several proposals have emerged offering guidelines for how to distribute the Covid-19 vaccine fairly. These include the Covid-19 Vaccines Global Access (COVAX) facility, a collaboration that brings together governments, companies, international organizations, and others to accelerate the development and manufacture of Covid-19 vaccines. Currently, COVAX is set up so that in a first phase poor countries can vaccinate 3% of their populations, while rich countries can vaccinate up to 50%. Another sophisticated proposal, the "Fair Priority" model, suggests countries with vaccines contribute to global distribution once their Covid-19 transmission rates drop below 1.

However, insofar as the aim is to have the greatest health impact, these proposals fall short, according to Hassoun and her team. They offer three suggestions:

1. Proposals for fair distribution must address health problems for individuals. Moreover, since most individuals have little choice as to their country of origin or residence, we should not discriminate against them based on location. A fair proposal cannot allow rich countries to hoard vaccines or prioritize their own populations first. Nor can it give individuals' less priority simply because they live in a country with less infrastructure, capacity, or willingness to distribute vaccines.

2. Allocation principles must explicitly focus on both direct and indirect health effects of Covid-19. Direct health effects include death and disability caused (in full or in part) by the virus. Indirect health effects include death and disability caused (in full or in part) by the social response to the virus.

3. Having the greatest global health impact requires assisting countries in their vaccine distribution, production, and consumption. A fair allocation system must consider how vaccine distribution will determine the success of whatever strategy is adopted.

"Many proposals for equitable allocation let rich countries prioritize their populations," said Hassoun. "We must combat this scarcity mindset and expand access rather than just shift resources around."
