CDC: Decreases in COVID-19 cases, ED visits, admissions, deaths, since vaccinations began

Editor's Note

This study by researchers from the Centers for Disease Control and Prevention (CDC) finds that since adult COVID-19 vaccinations began in the US in December 2020, there has been a:

• 40% decline in cases
• 59% decrease in emergency department (ED) visits
• 65% drop in hospital admissions
• 66% decline in mortality.

These declines were seen more in older adults, who had higher vaccination coverage, than in younger adults who had lower coverage.

The researchers also found that the administration of COVID-19 vaccines has steadily declined in adults since mid-April 2021. This suggests that efforts by state and local jurisdictions to increase coverage of all eligible age groups could result in further reductions in COVID-19 cases and severe outcomes, the researchers note.
