Well I may look at this in a different perspective

I look not at the viral load on a single patient, but at the viral load on planet earth. If a vaccine protects 50-90% of our population from contracting it also eliminates the vector from the same group of that population. If it is given to the high risk population less progression. Enrollment could be even more delayed. Less people with the disease, less severe to critical patients, less deaths.
Mutations? Less virions in the world, which requires a host for survival and replication, less opportunities for mutation. There are also many vaccine candidates pending. Continued surveillance of genetics mutations would take very little time to add different valences to the vaccine.
Those who said they care about lives, celebrate!
I think of myself as a surgeon, if I were angered with the use of seatbelts reducing my caseload of trauma surgery from car accidents. Really?
