LOS ANGELES, March 23 (Xinhua) -- Hospitalizations due to breakthrough COVID-19 infections are extremely uncommon, with fewer than 1 in 1,000 hospitalized with a case after getting vaccinated, a new study from Mayo Clinic suggested.
The study, published in Clinical Infectious Diseases, found that the hospitalization rate for vaccinated patients was 0.06 percent, or 6 in 10,000 patients, and 1 in 10,000 among those who have received their shot and acquired prior immunity through previous infection.
