In the process of being vaccinated against COVID-19, it was revealed that a man-made medical accident occurred in the United States, and several people were vaccinated with "air vaccine." Recently, a vaccine clinic in Virginia made a human error by injecting many people with an "air vaccine" instead of COVID-19 vaccine.

According to reports, a staff member of the Kroger Clinic in Florida mistakenly believed that another colleague had put COVID-19 vaccine into a syringe while vaccinating the public on the 8th. A spokesman for Kroger told the media that less than 10 people had been vaccinated against "air vaccine" instead of COVID-19, and apologized for negligence and inconvenience.

At first, a spokesman for Kroger said that some people had been mistakenly injected with saline instead of COVID-19 vaccine. But then a clarification statement issued by Kroger said: "after a thorough investigation, we have just received new information that people are being injected with empty syringes, not saline."

Vaccinating someone with an empty syringe will inject air into the body, which can hinder blood flow, according to health experts.

At present, Kroger has contacted all the affected people and re-vaccinated them against COVID-19. One of the men said in an interview: "it was a bit tingling when I played for the first time. This tingling is more painful than the flu vaccine I often get. But when I was vaccinated with the real COVID-19 vaccine, the situation was very different. I felt it right away. "
