Study: Older Americans saw larger declines in COVID-19 cases, deaths after vaccines became available
Older Americans experienced larger declines in COVID-19 cases, hospitalizations and deaths after the vaccine became available compared to those aged 18 to 49, according to a CDC study.
The study published on Tuesday examined the downward trend in cases, emergency department visits, hospital admissions and deaths among those 65 and older since before the vaccine was authorized in December.
The ratio of cases, emergency department visits, hospital admissions and deaths among those 65 and older compared to 18- to 49-year-olds decreased across the board since the time period when vaccines were not available.
At the same time, a higher portion of the older population, 82 percent, had received at least one dose of a vaccine by May 1, compared to 42 percent of 18- to 49-year-olds.
Conclusions: The CDC concluded that the difference among the age groups shows the effectiveness of the vaccines after the population with a higher rate of vaccinations saw a greater decline in cases, hospitalizations and fatalities.
“From November 29, 2020, to May 1, 2021, COVID-19 incidence, ED visits, hospital admissions, and deaths declined more in older adults, who had higher vaccination coverage, than in younger adults, who had lower coverage,” the study reads.
