In a new study from CDC, researchers found that among adults aged 65 years and older, vaccination is linked to a reduced risk for COVID-19-associated hospitalization.
In the study, the team examined the effectiveness of vaccination with the Pfizer-BioNTech and Moderna vaccines against COVID-19-associated hospitalization among people aged 65 years.
They tested 417 adults aged 65 years and older hospitalized with COVID-19-like illness (187 case patients with one or more positive test results for severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] and 230 controls with negative SARS-CoV-2 test results).
The researchers found that of the 187 case patients, 19 (10%) had received at least one dose of vaccine 14 days or more before illness onset (18 partially vaccinated and one fully vaccinated) compared with 62 (27%) of the 230 controls.
The vaccine effectiveness against COVID-19-associated hospitalization was estimated at 94% and 64% for full and partial vaccination, respectively.
The team says these findings suggest that continuing to rapidly vaccinate U.S. adults against COVID-19 will likely have a marked impact on COVID-19 hospitalization and might lead to reductions in post-COVID conditions and deaths.
