The COVID-19 vaccine rollout significantly cut cases, deaths, hospitalizations and emergency department visits among U.S. adults, according to the CDC's latest Morbidity and Mortality Weekly Report published June 8.
CDC researchers analyzed data on these metrics by age group for two time periods: Nov. 29 to Dec. 12, 2020 (the prevaccination period), and April 18 to May 1.
Five findings:
1. By May 1, 82 percent of adults 85 and over had received at least one vaccine dose, along with 63 percent of those 50-64, and 42 percent of adults ages 18-49.
2. Between April 18 and May 1, COVID-19 incidence was 69 percent lower among all adults compared to the prevaccination period.
3. Emergency department visits for COVID-19 also decreased 59 percent among all adults.
4. The rate ratio of COVID-19 hospital admission rates among people ages 70 and up compared to those ages 18-49 was down 65 percent by May 1.
5. The rate ratio of deaths among adults age 65 and over compared to adults ages 18-49 declined 66 percent over the same time period.
"These results suggest that tailored efforts by state and local jurisdictions to rapidly increase vaccine coverage among all eligible age groups could contribute to further reductions in COVID-19 cases and severe outcomes," the CDC said.
