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.
CDC Expands Booster Shot Eligibility and Strengthens Recommendations for 12-17 Year Olds
CDC now recommends that adolescents age 12 to 17 years old should receive a booster shot 5 months after their initial Pfizer-BioNTech vaccination series.
Data show that COVID-19 boosters help broaden and strengthen protection against Omicron and other SARS-CoV-2 variants. ACIP reviewed the available safety data following the administration of over 25 million vaccine doses in adolescents; COVID-19 vaccines are safe and effective.
At this time, only the Pfizer-BioNTech COVID-19 vaccine is authorized and recommended for adolescents aged 12-17.
For some immunocompromised children aged 5-11 years old, CDC recommends an additional dose of thePfizer-BioNTech COVID-19 vaccine to complete the primary series – a total of three doses.
Isolation and Quarantine
CDC has been monitoring the emerging science on when and for how long a person is maximally infectious with Omicron, as well as the effectiveness of COVID-19 vaccines and booster doses against Omicron infection.
CDC has updated COVID-19 isolation and quarantine recommendations with shorter isolation (for asymptomatic and mildly ill people) and quarantine periods of 5 days to focus on the period when a person is most infectious, followed by continued masking for an additional 5 days.
With the recommended shorter isolation and quarantine periods, it is critical that people continue to wear well-fitting masks and take additional precautions for 5 days after leaving isolation or quarantine.
You can end isolation after 5 full days if you are fever-free for 24 hours without the use of fever-reducing medication and your other symptoms have improved.
Mask use and layered prevention strategies, such as receiving all recommended vaccination and booster doses, physical distancing, screening testing, handwashing, and improved ventilation, are key to preventing COVID-19 and decreasing transmission.
Stay Up to Date with Your Vaccines
CDC recommends that people remain up to date with their vaccines, which includes additional doses for individuals who are immunocompromised or booster doses at regular time points. Individuals who are moderately or severely immunocompromised should get an additional primary shot and a booster shot.
Studies show after getting vaccinated against COVID-19, protection decreases over time and may also be decreased due to changes in circulating variants. The recent emergence of the Omicron variant further increases the importance of vaccination and boosters to protect against COVID-19.
Current surveillance data from the United States demonstrate that it is critically important for people to remain up to date with CDC’s vaccine recommendations. In November, those who were unvaccinated were more than 3 times more likely to test positive for infection compared to those who were vaccinated and more than 9 times likely compared to those who were boosted.
COVID Data Tracker Weekly Review
COVID-19 cases and hospitalizations are rapidly increasing across the United States, due largely to the highly contagious Omicron variant. CDC recently updated its quarantine and isolation recommendations for people who have COVID-19 or have been exposed.
Coronavirus Disease 2019 (COVID-19) in the U.S.

US states, territories, and District of Columbia have reported 58,689,973 cases of COVID-19 in the United States.
CDC provides updated U.S. case information online daily.
In addition to cases, deaths, and laboratory testing, CDC's COVID Data Tracker now has a Vaccinations tab to track distribution of COVID-19 vaccines in your state.
