HealthDay News — The Pfizer-BioNTech, Moderna, and Janssen COVID-19 vaccines are highly effective for preventing COVID-19-associated hospitalization among older adults in the United States, according to research published in the August 6 early-release issue of the US Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report.
Heidi L. Moline, MD, from the CDC COVID-19 Response Team, and colleagues examined the real-world effectiveness of the 3 currently authorized COVID-19 vaccines among individuals aged 65 years and older during February 1 to April 30, 2021. Data from 7280 patients from the COVID-19-Associated Hospitalization Surveillance Network were analyzed with vaccination coverage data.
The researchers found that the effectiveness of full vaccination in preventing COVID-19-associated hospitalization was 96, 96, and 84% for the Pfizer-BioNTech, Moderna, and Janssen vaccine products, respectively, among adults aged 65 to 74 years. Among adults aged 75 years or older, the effectiveness of full vaccination in preventing COVID-19-associated hospitalization was 91, 96, and 85%, respectively.
“These findings provide additional evidence that available vaccines are highly effective in preventing COVID-19-associated hospitalizations and demonstrate that performance of COVID-19 vaccines can be assessed using existing disease surveillance and immunization data,” the authors write. “Efforts to increase vaccination coverage are critical to reducing the risk for COVID-19-related hospitalization, particularly in older adults.”
