Human rights law can provide a transparent and fair framework for vaccine allocations, researchers suggest. - All countries face the ethical challenge of how to allocate limited supplies of safe, effective COVID-19 vaccines - Researchers say that governments should look to human rights principles and commitments to help them decide who should get priority for the first available doses of COVID-19 vaccine. - A human rights approach would include social vulnerability alongside medical vulnerability in decision-making because health is affected by social factors. - National vaccine roll-outs should take account of these overlapping vulnerabilities As Governments around the world wrestle with the question of designing a fair system to allocate their COVID-19 vaccine supplies for maximum protection against the pandemic, a team of researchers led by Dr Sharifah Sekalala of Warwick Law School propose that existing human rights legal principles should guide their thinking.
