The drug company, which it described as a “mistake,” confirmed that saline was injected in place of the COVID-19 vaccines in a mix.
A spokesperson for local media said that “a limited number” of people have been affected by the virus, which occurred in a store in Monroe, North Carolina.
Walgreens said those affected have been informed and offered a vaccine about when they will return.
“We are investigating what happened and have taken immediate steps to review our procedures with the site to prevent this from happening again,” the company said in a statement.
A woman who reported being among those affected said her trial happened on March 20, when she and her husband were to get the Pfizer vaccine at the Venture Street store.
The patient, Lisa Straw, said the pharmacist forgot to mix the vaccine, which resulted in only one injection of saline solution.
The bug was discovered when they realized that at the end of the vaccination process, he still had as many vaccinations as he should have been vaccinated, according to today’s account.
According to the Food and Drug Administration (FDA), saline injection may be used as a source of hydration and electrolytes. Patients with conditions such as congestive heart failure or liver or kidney disease need to take them with special caution.
The FDA has reported the use of saline in clinical trials of the two vaccines Covid-19 Moderna and Pfizer-BioNTech.
Last week, Walgreens announced that it was rolling out COVID-19 vaccines in most of its stores in 49 US states, Washington, D.C. and Puerto Rico. The company said it had administered more than 11 million injections as of April 12.
Walgreens was one of many companies to stop using the Johnson & Johnson vaccine after the Food and Drug Administration and the Centers for Disease Control. Disease control and prevention (CDC) recommends a pause in its administration.
The agencies announced an investigation into six cases of rare blood clots in patients who received the vaccine. According to the CDC, all six of the 6.8 million doses of J&J vaccine administered in the United States have been reported.
