Vaccine haves and have-nots. Stepping into 2021, let’s take a look at the potential tail risks presented by vaccine development.

On the flip side, if such vaccines are not readily available, a sharp dichotomy between the (vaccinated) rich world and (unvaccinated) others could have tremendous negative implications on market sentiment towards emerging markets in 2021.
