COVID-19 Vaccine Update

Last updated March 7, 2022

COVID-19 Booster

The Town of Nantucket, in partnership with the State of Massachusetts, is offering COVID-19 boosters to qualified residents. Booster sign ups can be found on the Town of Nantucket’s website.

Third-Dose For Immunocompromised Patients 

Evidence continues to demonstrate that the COVID-19 vaccinations offered here on Nantucket (Pfizer, Moderna and Johnson and Johnson) are remarkably effective for reducing risk of serious illness caused by COVID-19. While effective, the immunocompromised population is still vulnerable to COVID-19 because of their high-risk status for serious, prolonged illness and weakened immune systems.

The CDC recommends people who are moderately or severely immunocompromised should consider and consult with their healthcare provider on receiving a third-dose of their mRNA COVID-19 vaccine, in the month following the completion of the initial two-dose series.

It should be noted, that this CDC recommended third dose is not a booster dose, which is given to individuals when their immune response to the initial two-dose series has decreased. This third dose is a continuation of the two-dose series and is intended to help improve an immunocompromised individual’s response to their original two-dose series. The major difference between these two doses is the prescribed time between doses, the third-dose is recommended for about a month following the end of the two-dose series, whereas the booster is recommended at least 6-months following the end of the two-dose series.
