Health Ethics

Write a paper nine pages in length, double spaced, with a twelve point, times new roman font, and one inch margins. In the paper, consider ONE of the following cases:
1) Canada recently pledged a total of 200 million COVID-19 vaccine doses to a program distributing them to low and middle income countries. At the same time, Canada has been criticized for not following through or acting fast enough on its promises to distribute vaccines abroad.

How should Canada have prioritized its own vaccine needs against those of other countries? Is its current proposal to distribute 200 vaccine doses sufficient and timely, too little too late, or a failure to protect the interests of Canadians? What values are related to distributive justice are relevant to answering this question?
