Below, find a list of town-by-town vaccination rates. The percentages represent the share of Granite Staters older than 12 who have received a full vaccine series – one shot for the Johnson & Johnson vaccine and two shots for the Moderna and Pfizer vaccines.

The data isn’t perfect. This list, provided by the N.H. Department of Health and Human Services, calculates vaccination rate using the population of each town as is listed on U.S. Census Bureau 2019 population estimates, which is a slightly imperfect measure.

The Monitor has also removed certain towns from the list for various reasons such as extremely small populations that inflate or deflate vaccination data and vaccination rates that exceed 100% because of changing Census numbers.

What we know about the Delta variant

The Delta variant is now the predominant strain of COVID-19 in New England. As of late July, the strain comprised 83% of the tested cases and New Hampshire’s health department has detected 93 cases. Here’s what we know about the variant:

■ The Delta variant is nearly twice as contagious as the previous versions of the virus.

■Some studies have found that the variant may cause more severe illness than previous strains. Data collected from studies in Canada and Scotland found that people sick with the Delta variant were more likely to be hospitalized than those sick with other strains of the virus.

■Vaccines are still extremely effective at preventing severe cases of COVID-19 however no vaccines are 100% effective. It is still possible for fully vaccinated people to contract the virus, though this is exceedingly rare – 99% of the people who contracted the virus in New Hampshire between February and mid-June were unvaccinated.

■The CDC now recommends that all people in areas of substantial or high levels of community transmission – which now includes all of New Hampshire – wear masks indoors. This gives vaccinated people an extra layer of protection against breakthrough infections and prevents the virus from spreading as quickly through a community, which could create new variants.

■Unvaccinated Granite Staters are at severe risk of contracting this dangerous COVID-19 variant. Vaccines are widely accessible and free across New Hampshire. Go to vaccines.gov for more information.

Levels of community transmission

All of New Hampshire’s counties now either have a “substantial” or “high” level of COVID-19 transmission, which the Centers for Disease Control says makes masks necessary indoors.

State health officials have issued no formal advisory to residents in those counties to begin wearing masks inside again. The state mask mandate lapsed in mid-April and most towns have let their local rules expire.

Due to the highly contagious Delta variant, the CDC tightened its mask guidance at the end July, recommending that both unvaccinated and vaccinated people wear masks in areas with substantial to high levels of community transmission. As of this week, this guidance applies to all New Hampshire counties.

The CDC divides U.S. counties into four categories of COVID transmission – low, moderate, substantial and high – based on factors like population and new cases. Community transmission levels are regularly updated on the CDC’s COVID Data Tracker.
