Exactly. And just to drill a bit deeper into the science, the data out of Massachusetts is that only 1/10th of one percent of fully vaccinated people have developed so-called "breakthrough infections" (4.2 million people fully vaxed, 4450 breakthrough cases), and of those, 1.78% have died. That represents a death rate of 0.0019% among the fully vaxed. In addition, only 6.8% of the fully vaxed people who developed breakthrough infections that required hospitalization.
Obviously, the sooner we're able to get shots into the arms of kids the better. Nationwide, there is a much higher incidence of disease among younger people, especially with respect to the delta variant.
