SOMERVILLE, NJ – Beginning today, October 22, the Somerset County Department of Health will begin administering Moderna and Johnson & Johnson (Janssen) COVID-19 booster shots to certain eligible populations at its COVID-19 vaccination clinics. The approval from the US Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) expands booster doses to all three vaccines for populations who will benefit from additional protection.


The booster shot for Moderna is a half-dose and will be given at least six or more months after completing their primary series. Eligible recipients are in line with the guidelines for the Pfizer-BioNTech booster vaccine, including:

People aged 65-years and above
People aged 18 to 64-years who have underlying conditions
People aged 18 to 64-years with an increased risk of becoming infected by COVID-19 due to time spent in an occupational or institutional setting
Johnson & Johnson (Janssen)

As for the Johnson & Johnson (Janssen) COVID-19 vaccine, it can be given at least two or more months after completion of the initial vaccination to individuals 18 years of age and older.

Mix and Match for booster dosing

The CDC’s recommendations include a mix and match dosing for booster shots. For those eligible individuals, they may now choose which vaccine they will receive for their booster dose. Some may prefer a different vaccine type than they originally received, and this recommendation allows for that.

Eligible individuals must bring proof of vaccination and Somerset County residency to receive a Moderna, Pfizer-BioNTech, or Johnson & Johnson (Janssen) COVID-19 booster dose. All Somerset County COVID-19 vaccination clinics are listed at
