As of December 2, 2021, more than 234 million people in the United States have received at least one dose of a COVID-19 vaccine. However, vaccination among pregnant people remains low. CDC’s COVID Data Tracker shows that as of November 27, 2021, the proportion of fully vaccinated pregnant people has increased to 35%, but most pregnant people remain unprotected against COVID-19. CDC recommends that people who are pregnant, breastfeeding, trying to get pregnant now, or who might become pregnant in the future, get vaccinated against COVID-19. CDC also recommends that fully vaccinated pregnant people 18 years and older receive a COVID-19 booster dose.

People who are pregnant or were recently pregnant are at increased risk for severe illness from COVID-19, including ICU admission, ventilator use, and death. A recent studyexternal icon found that for pregnant people with COVID-19 after Delta became predominant, the risk of ICU admission was 66% higher than before Delta became predominant. The risk of needing a ventilator or special equipment to breathe was 63% higher, and the risk of death was more than 2 times higher than in the pre-Delta period.* A second study found that compared with people without a COVID-19 diagnosis at delivery, pregnant people with a COVID-19 diagnosis at delivery had nearly twice the risk of having a stillbirth.** After Delta become predominant, women with COVID-19 during pregnancy had 4 times the risk of having a stillbirth.

Getting a COVID-19 vaccine can prevent severe illness, death, and pregnancy complications related to COVID-19. CDC data show that COVID-19 vaccines are safe for people who are pregnant, including those early in pregnancy. Additionally, there is currently no evidence that any vaccines, including COVID-19 vaccines, cause fertility problems in women or men. Many people have become pregnant after receiving a COVID-19 vaccine, including some who got vaccinated during COVID-19 vaccine clinical trials. If you have questions about getting vaccinated, talk with your healthcare provider. To find a vaccine provider near you, visit vaccines.gov; text your ZIP code to 438829 (GETVAX); or call 1-800-232-0233.

*The risk for severe illness also increased for non-pregnant women of reproductive age (15─44 years) with COVID-19 during the Delta period, compared with the pre-Delta period.

**COVID-19 diagnosis may have represented a current or past infection.

Note to readers: CDC’s COVID Data Tracker now features a Pregnancy Data page which catalogs all pregnancy-related data available on COVID Data Tracker and provides links to resource on COVID-19 in pregnancy. Resources and tools are available to help people who are pregnant, breastfeeding, and new parents caring for infants protect their health.

What's New

Reported Cases

The current 7-day moving average of daily new cases (86,413) decreased 8.5% compared with the previous 7-day moving average (94,393). A total of 48,628,787 COVID-19 cases have been reported as of December 1, 2021.

On November 26, 2021, the World Health Organization (WHO) classified a new variant, B.1.1.529, as a Variant of Concern (VOC) and named it Omicron. On November 30, 2021, the United States also classified it as a VOC. On December 1, 2021, CDC announced that the first confirmed case of Omicron variant had been detected in the United States. Additional suspected cases of Omicron are being investigated. Despite the detection of Omicron, Delta remains the predominant strain in the United States. Nowcast projections* for the week ending November 27, 2021, estimate the national and regional proportions of Delta to be greater than 99%.

CDC has been actively monitoring and preparing for this variant and will continue to work with other U.S. and global public health and industry partners to learn more. For more information on variant proportions, visit COVID Data Tracker.

* 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 348,267 historical cases reported retroactively, 574 were reported in the current week and 11,899 were reported in the prior week.

Vaccinations

The U.S. COVID-19 Vaccination Program began December 14, 2020. As of December 2, 2021, 464.4 million vaccine doses have been administered. Overall, about 234.3 million people, or 70.6% of the total U.S. population, have received at least one dose of vaccine. About 197.8 million people, or 59.6% of the total U.S. population, have been fully vaccinated.* About 43.0 million additional/booster doses in fully vaccinated people have been reported. As of December 2, 2021, the 7-day average number of administered vaccine doses reported (by date of CDC report) to CDC per day was 1,428,263, a 22.0% increase from the previous week.

CDC’s COVID Data Tracker Vaccination Demographic Trends tab shows vaccination trends by age group. As of December 2, 2021, 99.9% of people ages 65 years or older have received at least one dose of vaccine and 86.4% are fully vaccinated. More than three-quarters (83.0%) of people ages 18 years or older have received at least one dose of vaccine and 71.3% are fully vaccinated. For people ages 12 years or older, 81.0% have received at least one dose of vaccine and 69.5% are fully vaccinated. For people ages 5 years or older, 75.0% have received at least one dose of vaccine and 63.4% are fully vaccinated.

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: Hospitalizations in Non-Hispanic American Indian and Alaska Native 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 been at increased risk for COVID-19-associated hospitalizations compared to non-Hispanic White people. For the week ending November 13, 2021, the rate of COVID-19-associated hospitalizations in non-Hispanic American Indian/Alaska Native people was 23 per 100,000 people. This is the highest hospitalization rate among all racial and ethnic minority groups and represents a substantial increase over the past three months.*

* It is important to note that these increases might be driven by a limited number of COVID-NET sites and might not be nationally representative.

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 standardized case reporting form.
