A COVID-19 vaccination site in Colorado closed early Wednesday after patients experienced adverse reactions to the Johnson & Johnson single vaccine.
Centura Health, which helps run Dick’s Sporting Goods Park’s community vaccination center, said in a statement posted on Twitter that 11 patients who received the vaccine experienced adverse reactions.
Only two of the patients were taken to hospitals for further observation “with great caution.”

Centura Health said the number of people who experienced adverse events was equal to 0.62 percent of the more than 1,700 people who were vaccinated Wednesday at the site. The 640 patients who were unable to be vaccinated have been rescheduled to be vaccinated on April 11th.
In a separate statement, state officials said there is no reason for other people vaccinated at the site on Wednesday to be concerned.
“The state has no reason to believe that people vaccinated today at Dick’s Sporting Goods Park should be concerned,” the statement said. “Adverse reactions are usually immediate. Healthcare providers monitor patients’ reactions after administering the vaccines for at least 15 minutes after the injection (or for 30 minutes if the patient has a history of anaphylaxis) for this reason. This event does not affect other vaccine providers. ”
About 80,000 doses of Johnson & Johnson vaccine have been administered in Colorado since early March, officials said. Overall, there are more than 1.9 million people in the state at least one dose of a coronavirus vaccine, while 1,145,039 have been completely vaccinated.
The USA Centers for Disease Control and Prevention (CDC) says nausea, fever, cells and fatigue are among the possible side effects that can occur after the vaccine. They usually start within a day or two of getting the vaccine and should go away within a few days.
Clinical trials have shown that the Johnson & Johnson vaccine is 66% effective in the overall prevention of COVID-19 and 85% efficacy in the prevention of serious cases.
