This message includes updates on the COVID-19 response from CDC. The COVID-19 Outbreak is a rapidly evolving situation and information will be updated as it becomes available.
Two Years of COVID-19 Vaccination
December 2022 marked two years since the first COVID-19 vaccine was administered in the U.S. Although too many lives have been lost to COVID-19 since the start of the pandemic, vaccination has helped prevent millions of hospitalizations and saved millions of lives.
Stay up to date on your vaccines to protect yourselves, your loved ones, and your community against COVID-19. As with other vaccine-preventable diseases, you are protected best from COVID-19 when you stay up to date with the recommended vaccinations, including recommended boosters.
Get an updated bivalent booster at least 2 months after completing your primary series or last booster. If you’ve had COVID-19, you may delay getting your booster by 3 months since your symptoms ended.
Flu Vaccine and COVD-19 Boosters
Studies conducted throughout the COVID-19 pandemic indicate that it is safe to get both a flu vaccine and a COVID-19 vaccine at the same visit.
To find COVID-19 vaccine locations near you, visit vaccines.gov, text your ZIP code to 438829, or call 1-800-232-0233.
Ensuring COVID-19 Vaccine Safety
To make sure that COVID-19 vaccines are safe, CDC expanded and strengthened the country’s ability to monitor vaccine safety. CDC created new web-based platforms to gather information and give CDC scientists information about the safety of COVID-19 vaccines in real time.
COVID Data Tracker Weekly Review
The most recent Omicron sublineage, XBB.1.5, is on the rise across the United States. Projections can be uncertain when a variant is just beginning to spread, and CDC is continuing to investigate the ways in which XBB.1.5 may be different from other Omicron lineages.
This week’s COVID Data Tracker Weekly Review explains weighted estimates and Nowcast estimates, the two methods CDC uses to display variant proportions.
