Less than 1% of fully vaccinated people experienced a breakthrough infection, according to a Kaiser Family Foundation analysis of official state data. The federal government only reports data on breakthrough infections that result in hospitalization or death. That’s about 6,600 severe breakthrough cases out of more than 163 million fully vaccinated people. But the KFF analysis shows that breakthrough infections of any kind are also extremely rare. About half of states report data on Covid-19 breakthrough cases, and in each of those states, less than 1% of fully vaccinated people had a breakthrough infection, ranging from 0.01% in Connecticut to 0.9% in Oklahoma.
