Rates of COVID-19-Associated Hospitalizations by Vaccination Status in Adults Ages 50–64 Years, October–December 2021
COVID-19 cases and hospitalizations are starting to decline across the United States. However, deaths are still rising, and community transmission is still high nationwide. As of January 27, 2022, more than 211 million people in the United States have received a primary series of a COVID-19 vaccine and are considered fully vaccinated. More than 86 million people are up to date with their COVID-19 vaccines, which means they have received all recommended COVID-19 vaccines, including boosters.
Two new CDC reports show that people who are up to date with their COVID-19 vaccines have the highest amount of protection against both the Delta and Omicron variants.1,2 One report found that, compared to up-to-date adults, unvaccinated adults had five times the risk of infection and more than 50 times the risk of COVID-19-associated death. A second report found that a third dose (either an additional primary dose or booster dose) of an mRNA COVID-19 vaccine (Pfizer-BioNTech or Moderna) was highly effective at preventing emergency and urgent care visits and hospitalizations related to COVID-19.
COVID Data Tracker’s Hospitalizations by Vaccination Status – COVID-NET tab features more new data showing the effectiveness of vaccines and boosters. In December 2021, for example, unvaccinated adults ages 65 years and older were 49 times more likely to be hospitalized for COVID-19 than people in that age group who were up to date with their COVID-19 vaccines.
All of this information highlights the importance of staying up to date with COVID-19 vaccination, given how easily the Omicron variant spreads. As of January 27, 2022, 67.6% of people ages 5 years and older in the United States are fully vaccinated. However, there are still millions of people who are eligible for a booster dose who have not yet received one. Everyone 12 years and older who has received their primary series of a COVID-19 vaccine is now eligible for a booster shot if enough time has passed since completion of their primary series. It’s fast, easy, and free. To find a vaccine provider near you, visit vaccines.gov.

Reported Cases
As of January 26, 2022, the current 7-day moving average of daily new cases (596,860) decreased 19.9% compared with the previous 7-day moving average (744,806). A total of 72,874,041 COVID-19 cases have been reported in the United States as of January 26, 2022.
Currently two variants, Omicron and Delta, are classified as Variants of Concern (VOC) in the United States. CDC Nowcast projections* for the week ending January 22, 2022, predict the national proportion of Omicron to be 99.9% (95% PI 99.8-99.9%) and Delta to be 0.1% (95% PI 0.1-0.2%). Omicron is predicted to be greater than 99% in all HHS regions.

*The median time from specimen collection to sequence data reporting is about 3 weeks. As a result, weighted estimates for the most recent few weeks may be unstable or unavailable. CDC’s Nowcast is a data projection tool that helps fill this gap by generating timely estimates of variant proportions for variants that are circulating in the United States. View Nowcast estimates on CDC’s COVID Data Tracker website on the Variant Proportions page.
**Historical cases are excluded from daily new cases and 7-day average calculations until they are incorporated into the dataset for the applicable date. Of 399,384 historical cases reported retroactively, none were reported in the current week and 46,706 were reported in the prior week.

Vaccinations
The U.S. COVID-19 Vaccination Program began December 14, 2020. As of January 27, 2022, 536.4 million vaccine doses have been administered in the United States. Overall, about 249.3 million people, or 75.1% of the total U.S. population, have received at least one dose of vaccine. About 211.2 million people, or 63.6% of the total U.S. population, have been fully vaccinated.* About 86.5 million additional or booster doses have been reported in people who have been fully vaccinated; however, 51.8% of the total booster-eligible population has not yet received a booster dose. As of January 27, 2022, the 7-day average number of administered vaccine doses reported (by date of CDC report) to CDC per day was 643,725, a 41.2% decrease from the previous week.
CDC’s COVID Data Tracker Vaccination Demographic Trends tab shows vaccination trends by age group. As of January 27, 2022, 95.0% of people ages 65 years or older have received at least one dose of vaccine and 88.3% are fully vaccinated. For people ages 18 years or older, 86.7% have received at least one dose of vaccine and 74.0% are fully vaccinated. For people ages 12 years or older, 84.9% have received at least one dose of vaccine and 72.4% are fully vaccinated. For people ages 5 years or older, 79.8% have received at least one dose of vaccine and 67.6% are fully vaccinated.

Daily Trends in Number of New COVID-19 Hospital Admissions in the United States
New admissions are pulled from a 10 am EST snapshot of the HHS Unified Hospital Timeseries Dataset. Due to potential reporting delays, data from the most recent 7 days, as noted in the figure above with the grey bar, should be interpreted with caution. Small shifts in historic data may also occur due to changes in the Centers for Medicare and Medicaid Services (CMS) Provider of Services file, which is used to identify the cohort of included hospitals.
COVID-NET: Trends in Hospitalizations among Non-Hispanic Black People
CDC’s Coronavirus Disease 2019-Associated Hospitalization Surveillance Network (COVID-NET) shows that since the start of the pandemic, people from racial and ethnic minority groups have experienced disproportionately higher rates of COVID-19-associated hospitalizations compared to non-Hispanic White people. Beginning in mid-December, the weekly COVID-19-associated hospitalization rates for non-Hispanic Black people have risen sharply, especially when compared to other groups. For the week ending January 8, 2021, preliminary data not adjusted for age show rates of COVID-19-associated hospitalizations in non-Hispanic Black people were 60.5 per 100,000 population—more than twice as high as the overall weekly rate of hospitalization (29.7 per 100,000 population) and almost 3 times as high as rates among non-Hispanic White people (21.2 per 100,000 population).
Hospitalization Rates among Select Race and Ethnicity Groups
The Coronavirus Disease 2019 (COVID-19)-Associated Hospitalization Surveillance Network (COVID-NET) is an additional source for hospitalization data collected through a network of more than 250 acute-care hospitals in 14 states (representing ~10% of the U.S. population). Detailed data on patient demographics, including race/ethnicity, underlying medical conditions, medical interventions, and clinical outcomes, are collected with a standardized case reporting form.
