塔醫中心: CDC建議七種人加打第三劑新冠疫苗

 


 

 

 

Patient Update

 

Dear Tufts Medical Center and Tufts Children’s Hospital Community:

 

On August 13, 2021 the Centers for Disease Control and Prevention (CDC) provided new recommendations for the Pfizer and Moderna COVID-19 vaccines for moderately to severely immunocompromised people. The CDC now recommends a third dose of the Pfizer or Moderna COVID-19 vaccine for these individuals.

 

Tufts MC’s COVID-19 Vaccine Clinic at 276 Tremont Street is now administering third doses of the Pfizer and Moderna COVID-19 vaccine to moderately to severely immunocompromised individuals. If you meet the following criteria, you are eligible for a third dose:

 

  • Are actively being treated for cancer
  • Have received a solid organ transplant and are taking medicine to suppress the immune system
  • Have received CAR-T cell therapy
  • Have received a stem cell transplant within the last 2 years or are taking medicine to suppress the immune system after a stem cell transplant
  • Have moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome)
  • Have advanced or untreated HIV infection
  • Are taking high-dose corticosteroids (i.e., the equivalent of 20 or more milligrams of Prednisone a day) or are taking other drugs that may suppress the immune response.

 

Why was an additional third dose recommended?

People who are moderately to severely immunocompromised are more likely to become very sick if they get COVID-19. They may also have a longer illness and may not get the same protection from two doses of the Pfizer and Moderna COVID-19 vaccines as other people do. The available data suggests that they may receive more protection from a third dose of vaccine. 

 

If you are immunocompromised:

 

Do I need to get the same vaccine I got for the first two doses?

Yes, the third dose should be the same vaccine as the first two. Those who got Pfizer for their first two doses, should get Pfizer for their third and the same with Moderna.



What if I got the Johnson & Johnson (Janssen) vaccine?

At present, there are no recommendations for an additional dose of the Johnson & Johnson (Janssen) vaccine.

 

When should I get a third dose of vaccine?

The CDC recommends that the third dose be administered at least 28 days after receiving the second dose of either the Pfizer or Moderna vaccine. Please consult with the physician who prescribes your immunocompromising medication to best assess the timing for your third dose.

 

Are there side effects to the third dose?

To date, the side effects reported after the third dose of the Pfizer or Moderna vaccine were similar to what people experienced after receiving doses 1 and 2. Pain at injection site was the most commonly reported side effect. Most symptoms were mild to moderate and resolved within 3 days.

 

Can I stop wearing masks and social distancing if I get the third dose?

While the third dose of the vaccine may provide added protection, it is still recommended that you continue to wear a mask indoors in public spaces, anywhere that physical distancing by 6 feet is not possible, and continue to avoid crowds.

 

Where can I get the COVID-19 vaccine?

Tufts Medical Center’s COVID-19 Vaccine Clinic

276 Tremont Street

Hours: Monday to Friday from 8 am – 5 pm.



Appointments are encouraged and can be booked electronically at tuftsmcvaccine.org.

Do I need to bring a note from my doctor to get my third dose?

You do not need a doctor’s note to receive a third dose, but you will need to attest to being immunocompromised. You should also bring your CDC COVID-19 vaccine documentation.

 

Do I need a third dose or a booster if I am not immunocompromised?

The CDC does not recommend an additional third dose for any other population at this time. If you are fully vaccinated, there is nothing else for you to do at the moment. We will continue to keep you informed of any changes should there be further recommendations for booster shots or additional doses of the COVID-19 vaccine for people who are not immunocompromised. While booster doses are not recommended at this time; you may have seen in the news that guidance regarding booster doses is expected to be released soon. We will continue to keep you informed as more information becomes available.

 

What is the difference between an additional dose and a booster dose?

  • An additional “third dose” of vaccine is administered when the immune response following a primary vaccine series is considered to be insufficient. For example, in immunocompromised patients.
  • A booster dose is recommended after a primary vaccine series when the initial immune response is likely to have waned over time.

 

Thank you for doing your part to keep our community safe.
