COVID-19 Vaccine Update

Last updated May 27, 2021

After Saturday, May 29th, the community vaccination clinic at the VFW facility at 22 New South Road will close and no longer provide vaccine appointments. Nantucket Cottage Hospital is proud to have delivered over 16,000 doses of the COVID-19 vaccine at the VFW location. Several other locations around the island are now providing vaccinations to anyone who lives, works or studies in Massachusetts over the age of 12.

Third COVID-19 Dose Information

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.

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 Town of Nantucket is now offering third doses of COVID-19 vaccines to individuals who are moderately or severely immunocompromised. To request a third dose, individuals falling into these categories should reach out to either their primacy healthcare provider, or the Town of Nantucket Community Health Clinical Administrator at
