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 Eligibility for COVID-19 Booster Shots to All Adults
People age 18 years and older who received Pfizer-BioNTech or Moderna COVID-19 vaccines may get a booster six months after completion of their primary vaccination series.
Contact the location that set up your previous appointment. If you need to find a different location, there are several ways you can find a vaccine provider.
You may choose which COVID-19 vaccine you receive as a booster shot. Some people may prefer the vaccine type that they originally received, and others may prefer to get a different booster. CDC’s recommendations now allow for this type of mix and match dosing for booster shots.
If you are considering traveling for a holiday or event, visit CDC’s Travel page to help you decide what is best for you and your family. Delay travel until you are fully vaccinated.
Check your destination’s COVID-19 situation before travel. State, local, and territorial governments may have travel restrictions in place.
Wearing a mask over your nose and mouth is required in indoor areas of public transportation (including airplanes) and indoors in U.S. transportation hubs (including airports).
Do not travel if you have been exposed to COVID-19, you are sick, or if you test positive for COVID-19.
If you are not fully vaccinated and must travel, get tested both before and after your trip.
Antibodies and COVID-19
Antibodies to SARS-CoV-2, the virus that causes COVID-19, can be detected in the blood of people who have recovered from COVID-19 or people who have been vaccinated against COVID-19. Getting a vaccine is safer than getting COVID-19, and vaccination against COVID-19 is recommended for everyone ages 5 years and older.
If someone has already had COVID-19, vaccination against COVID-19 increases their body’s antibody response, which improves their protection.
It is important to remember that some people with antibodies may become infected after vaccination or after recovering from a past infection. The risk of infection, severe illness, hospitalization, and death are all much lower for vaccinated people compared to people who are unvaccinated.
COVID Data Tracker Weekly Review
Rates of COVID-19 hospitalizations remain high in children between the ages of 5 through 11 years. While COVID-19 is usually milder in children compared with adults, it can make children very sick. CDC recommends everyone ages 5 years and older get a COVID-19 vaccine to help protect against COVID-19.
