The vast majority of patients driving up Covid-19 hospitalizations in parts of the U.S. are unvaccinated, according to hospitals, some of which are reactivating surge plans used in the peak of the pandemic.
As the highly contagious Delta variant spreads nationwide, some hospital and public-health officials said they are preparing for hospitalizations to potentially reach new pandemic peaks where fewer people are vaccinated.
AdventHealth, which manages 41 hospitals across seven largely Midwestern and Southern states, said about 97% of roughly 12,700 Covid-19 patients treated this year were unvaccinated or partially vaccinated. The data excludes some AdventHealth hospitals managed under joint ventures.
Of the fully vaccinated Covid-19 patients who have been or are in AdventHealth hospitals, many have weakened immune systems due to cancer or other conditions, said Jeffrey Kuhlman, chief quality and safety officer for AdventHealth.
HCA Healthcare Inc., one of the nation’s largest hospital systems, said its data show fully vaccinated people account for less than 1% of its Covid-19 patients.
