Adverse Reactions Info Released Slowly After Temporary Shutdown of COVID-19 Mass Vaccination Clinic in Commerce City, Colorado

After a review of the 11 patients who had adverse reactions, there was no concern, according to the Colorado Department of Public Health. YouTube Tips ⓘ

Eleven people had an “adverse reaction” at a COVID-19 mass vaccination clinic sponsored by Centura Health and the state of Colorado, which prompted officials to close a mass vaccination clinic in Commerce City, Colorado (closes about 3:30 p.m. Wednesday, April 7, 2021). More than 1,700 shots were administered before 11 people presented adverse reactions. Kevin Massey, a spokesperson for Centura Health, said 11 people had an adverse reaction during a waiting period at the on-site observation site. He said two patients required transportation to a hospital for additional observation.




Next, more than 600 people with appointments were turned away from the “Vaccines for All” mass vaccination event at Dick’s Sporting Goods Park on Wednesday after the adverse reactions to the Johnson & Johnson vaccine, according to a statement from Centura Health. Dick’s Sporting Goods Park, located at 6000 Victory Way, is a soccer stadium venue that is also used for major concert events.

“Following the administration of the J&J vaccine and during onsite observation, we saw a limited number of adverse reactions to the vaccine.”

Initially, Centura officials did not provide specific details about the reactions, including the severity, or whether all the reactions were similar. Later the Tri-County Health department revealed symptoms included nausea and dizziness. NBC affiliate 9NEWS reported they have asked a lot of questions, such as what happens to the lot of J&J vaccine that was interrupted, but have received few answers.

Temporary Operational Pause at Dick’s Sporting Goods Park Community Vaccination Site on April 7

Centura Health decided to pause operations of the Vaccines for All mass vaccination event at Dick’s Sporting Goods Park Wednesday, April 7. We are hosting the clinic in partnership with the State of Colorado.

Following the administration of the J&J vaccine and during onsite observation, we saw a limited number of adverse reactions to the vaccine that equaled 0.62 percent of those receiving the vaccine Wednesday; more specifically, 11 patients experienced adverse reactions. Medical staff on site determined two individuals required additional observation and out of an abundance of caution, they were transported to nearby hospitals.

We followed our protocols and made the cautious decision – in partnership with the state – to pause operations for the remainder of the day. Normal operations are set to resume as scheduled on future clinic dates.

More than 1,700 patients received their shots Wednesday, and the 640 patients who were unable to receive their vaccine this afternoon will automatically be rescheduled for Sunday, April 11, at Dick’s Sporting Goods Park. Our goal is to continue to vaccinate Coloradans as quickly as possible while keeping our patients’ safety at the forefront.
