Most Americans know that African-Americans have a significantly lower life expectancy than White Americans. Most of us don’t think through the implications of that disparity. For example, all working people pay into Social Security, but African-Americans are less likely to live long enough to collect it. In this op-ed, published today in the Allentown, PA Morning Call, my colleague Tom McAndrew and I explore the implications of that racial gap for allocation of the Covid-19 vaccine. We point out that, if we allocate vaccines primarily by age, African-Americans will be seriously underrepresented.
