The 11 people who suffered from side effects to the Johnson & Johnson vaccine – leading to the closure of a vaccination site in Colorado – experienced symptoms such as nausea and dizziness, according to health officials.
Two people within that group were also taken to hospital for further observation, the Denver Post reported, citing a statement from the Colorado Department of Public Health and Environment.
The nine others were treated with juice and water, state officials said.
The health department stressed that the side effects experienced on Wednesday were “consistent with what can be expected” with the single dose. It said the decision to close the vaccination site at Dick’s Sports Goods Park in Commerce City was made out of an abundance of caution.
“The state has no reason to believe that people vaccinated at Dick’s Sporting Goods Park today should be concerned,” said the health department.
“In most cases, discomfort from fever or pain after vaccine administration is normal.”
More than 1,700 people were stabbed at the site on Wednesday – and the 11 who fell ill accounted for just 0.8 percent, said Kevin Massey, a Centura Health spokesperson.
“We followed our protocols and made the decision, with great caution, in conjunction with the state, to suspend operations for the rest of the day,” Massey told the Denver Post.
Centura Health operates the site in conjunction with the state health department.
The 640 people who were rejected on Wednesday will be moved to Sunday and receive the shot from Pfizer – which state officials said was previously scheduled for that day.
