What is the COVID-19 death rate of vaccinated vs. unvaccinated?

Serious breakthrough cases are no longer rare but remain uncommon, according to Michelle Barron, senior medical director of infection prevention with UCHealth [and professor of medicine at CU School of Medicine]. “I’d say two-thirds of our hospitalizations of individuals who are fully vaccinated are over the age of 60 and have underlying co-morbidities; whether it’s diabetes or obesity. The age is really an important distinction,” said Barron.
