New Hampshire is committed to a safe and effective vaccine that will protect against COVID-19. The City of Nashua Division of Public Health and Community Services (DPHCS) encourages all eligible individuals in our community to get vaccinated and boosted.

COVID-19 Vaccine Information

All currently authorized COVID-19 vaccines are safe and free. COVID-19 vaccines are effective at protecting people from getting seriously ill, being hospitalized, and dying from COVID-19. As with vaccines for other diseases, you are best protected when you stay up to date. CDC recommends that everyone 6 months of age and older get the COVID-19 vaccine. People who are moderately or severely immunocompromised have specific COVID-19 vaccine recommendations, which include an additional third dose.

Booster Vaccine

Boosters are an important step forward as we work to keep our communities safe. 

The CDC recommends that everyone who is eligible stay up-to-date on vaccinations by getting an updated booster dose at least 2 months after their last COVID-19 shot—either since their last booster dose, or since completing their primary series. Pfizer and Moderna updated vaccines are available for individuals 6 months and older. The CDC expanded the use to the youngest group of children (age 6 months to 5 years) on December 9, 2022.

These new boosters contain an updated bivalent formula that both boosts immunity against the original coronavirus strain and also protects against the newer Omicron variants that account for most of the current cases. Updated boosters are intended to provide optimal protection against the virus and address waning vaccine effectiveness over time.

Eligible individuals can get either the Pfizer or Moderna updated booster, regardless of whether their primary series or most recent dose was with Pfizer, Moderna, Novavax, or the Johnson & Johnson vaccine. As per the CDC’s recommendations, the new bivalent booster replaces the existing monovalent vaccine booster, therefore that vaccine will no longer be authorized for use as booster doses.

For children age 6 months to 5 years who get the Pfizer primary series, the updated bivalent vaccine will be used as the third dose in the series, rather than as a separate booster.

 To determine which booster is best for you or your loved one, contact your healthcare provider or visit the CDC's website.
