From a supply chain perspective, the goal of vaccination is to minimize demand for critical health care. We need to avoid hospitals being overwhelmed. Emergency room/ICU resources and staff are the crucial bottlenecks (hourglass structures) that are at highest risk of collapse. Our supply chain resilience objective is to maintain a reasonable equilibrium of demand and supply for critical health care. If this equilibrium can be maintained, deaths and disease can be minimized and economic continuity (recovery) can be maximized.
Just for the record, in the Sunday/Monday edition of the Wall Street Journal, I am quoted as saying vaccine consumption is not yet sufficient. While true, consumption is being restricted by overly-tight access to supply.
