Children under 12 can't be vaccinated yet, so what should parents do?

In the United States, just shy of half of all adults are fully vaccinated against COVID-19, and an additional 7.6 percent are at least partially vaccinated—a considerable feat, given the relatively short time (about six months) that inoculations have been widely available. However, the figures leave out an important demographic: So far, the federal Food and Drug Administration has not authorized any vaccine for children under 12 years old.
