Definitions and notes

Individuals with at least one dose: An individual is counted as having at least 1 dose if they have received one or more doses of vaccine. This is measured as the total number of 1st doses of Moderna and Pfizer vaccine administered and reported, plus the total number of Janssen/Johnson & Johnson doses administered and reported.

Fully vaccinated individuals: An individual is counted as fully vaccinated if they have received the number of doses required to complete the COVID-19 vaccine series. This is measured as the total number of 2nd doses of Moderna and Pfizer administered and reported plus the total number of Janssen/Johnson & Johnson doses administered and reported.

Partialy vaccinated individuals: An individual is counted as partially vaccinated if they have received only the 1st dose of a two-dose vaccine (currently Moderna and Pfizer).

Notes on race and ethnicity: NH= Native Hawaiian, PI = Pacific Islander, and AI/AN = American Indian/Alaska Native. Other include responses that do not fit into the listed categories, including non responses or “prefer not to say." Unknown includes records from selected providers whose software does not allow them to collect race and ethnicity data. Reported race and ethnicity are incomplete in MIIS (36% unknown ethnicity; 16% unknown race).

Notes on sex: Until values grow larger, all non-binary data are included in Other. Other also includes unknown responses where sex was not reported.

Notes on age: As of 5/20/21, the 0-19 years population category was split into 12-15 and 16-19 years to more closely reflect the population currently eligible for vaccines (12+). The total population for a given town includes all residents, including those ages 0-11. Total doses may include a small number of doses with ages incorrectly marked as 0-11 and thus sum of age group doses may not match total town doses.

Source: “Population Estimates 2011-2020, version 2019, Massachusetts Department of Public Health, Bureau of Environmental Health. Version 2019 years 2017-2019 apply updates from U.S. Census Bureau’s County Population by Characteristics, vintage 2019; all previous years apply updates from U.S. Census Bureau’s County Population by Characteristics, vintage 2018 or earlier. These estimates were developed by the University of Massachusetts Donahue Institute (UMDI) in partnership with the Massachusetts Department of Public Health, Bureau of Environmental Health.

UMDI detailed population estimates at fine levels of geography and demographic strata are prone to estimation error. UMDI Estimated error was best described by age and population size and was used to adjust final population numbers, however a margin of error exists for all estimates.

Note about Totals: The difference in the MA state population total created by summing the age categories and by summing the race categories is expected due to the manner in which the estimates were created; the discrepancy is due to unknown races and small, compounded rounding.

Source: MIIS. Immunization data from most (but not all) providers in Massachusetts are reported into the Massachusetts Immunization Information System (MIIS) through direct messages from electronic health records or direct entry by users. Due to inputting and processing, it may take 24-48 hours or more for shipping or administration data to appear in MIIS. MIIS data are available for analysis one calendar day after they are reported to the MIIS. Data are current as of time of publication and may be subject to change in future publications as additional data are reported.

Disclaimer: MIIS uses zip code to define a person’s location of residence. In an effort to provide municipality-level data, zip codes are linked to towns. However, this results in is less precise vaccination coverage estimates for small municipalities that share zip codes with neighboring jurisdictions. For this reason, we advise cities and towns with overlapping zip codes to aggregate relevant zip codes to more precisely estimate vaccination coverage in their municipality

MIIS administration data are collected by individuals' residence zip code. Due to some zip codes spanning multiple towns, and some towns not having a unique zip code identifier, 15 pairs of towns must be listed with a neighboring town based on a shared zip code. Population data are added together. These towns are noted in the data and listed below as follows: Town A, Town B, shared zip code.

Great Barrington, Alford, 01230
Chilmark, Aquinnah, 02535
North Adams, Clarksburg, 01247
Lanesborough, Hancock, 01237
Charlemont, Hawley, 01339
Greenfield, Leyden, 01301
Westfield, Montgomery, 01085
Egremont, Mount Washington, 01258
Lanesborough, New Ashford, 01237
Amherst, Pelham, 01002
Hinsdale, Peru, 01235
Athol, Phillipston, 01331
Granville, Tolland, 01034
Becket, Washington, 01223
Easthampton, Westhampton, 01027

Three towns have multiple overlapping zip codes with other towns: Alford, Leyden, and Montgomery. The populations for these towns are added to the neighboring town listed (see above), though some administrations may have been received by residents captured by a different zip code shared by a neighboring town.
