90% of deaths are in the oldest 1/3 of the population. So, we are waiting for a vaccine that will probably (hopefully) be very effective for those who comprise a strong majority of the population yet who will see the least benefit.

The elderly will still be out in the cold, not knowing if the vaccine will even work for them. For something as virulent as COVID among the elderly, 30% might be optimistic. In other words, if your plan is to lock down and wait for a vaccine, you may want to work on a better plan. The folks that have something to fear will never be safe.
