Pop-Up COVID-19 Vaccine Clinics and Testing in Union County in September

Free COVID-19 shots and saliva testing to be provided to residents at events in 6 County municipalities


Union County, NJ – The Union County Board of County Commissioners informs residents that free COVID-19 vaccines and testing will be available at convenient pop-up clinics throughout the County during the month of September. The upcoming clinics will be held in Rahway, Hillside, Elizabeth, Union Township, Roselle and Scotch Plains.

All residents are strongly urged to get their vaccine as soon as possible as new strains of the virus emerge and spread. Third doses of the Pfizer and Moderna vaccines for residents who are immunocompromised will also be available at the upcoming mobile clinics.

In addition to free vaccinations, residents can also get a free COVID-19 saliva test at any of the pop-up clinics. Residents can also get vaccinated for COVID-19 at Union County’s vaccine clinics in Elizabeth, Plainfield, and Union Township.

“We urge unvaccinated residents to make an appointment at any of our vaccination sites as soon as possible and ask that they encourage family and friends to get their shot, too,” said Union County Commissioner Board Chairman Alexander Mirabella. “Immunocompromised residents who are eligible for a third dose should also make an appointment as soon as possible for added protection.”

Union County began offering pop-up COVID-19 vaccination clinics in local communities earlier this year, in order to reach vulnerable populations including seniors, homeless individuals, and others who would have difficulty traveling to a centralized vaccine site.

“The Board of County Commissioners will continue to provide residents with opportunities for vaccination and testing,” said Commissioner and Chair of the Public Safety Committee Sergio Granados. “Easy access to vaccines and testing remains our focus as vaccination is key to keeping Union County residents safe as we continue to navigate COVID-19 and its variants.”

The County’s pop-up program has now expanded to include all age-approved Union County residents. Currently, any resident age 12 and older is eligible for the Pfizer vaccine. Eligibility for the Moderna and Johnson & Johnson vaccines begins at age 18. Those who receive the first dose of a two dose vaccine (Pfizer or Moderna) at one of Union County’s Mobile Vaccinations Clinics will receive instructions as to how and when to receive their second dose. Currently, third doses of the two dose vaccines are available for immunocompromised residents.

Any Union County resident can make an appointment at any of the following clinics, regardless of their home town:

  • Wednesday, September 1 in Rahway at 7th and 8th Grade Academy, 1139 Kline Place, 5:00 p.m. – 7:00 p.m. (Johnson & Johnson/Pfizer vaccines/COVID-19 Saliva Testing)
