The spike in hospitalizations of unvaccinated adults — which are almost all preventable — cost the U.S. health system more than $2 billion in June and July, per a KFF analysis.

Why it matters: Those costs are ultimately shouldered by all of us, not just those who remain unvaccinated and then get severely ill.

By the numbers: A coronavirus hospitalization costs, on average, around $20,000.

Using CDC data, KFF estimated that there were around 37,000 preventable coronavirus hospitalizations among unvaccinated adults in June and another 76,000 in July.
