NEW YORK (AP) – It’s anxiety – not a problem with images that cause fainting, dizziness and other short-term reactions in dozens of people at coronavirus vaccine clinics in five states, US health officials have concluded.

Experts said the group detailed Friday by the Centers for Disease Control and Prevention is an example of a decades-old phenomenon from different vaccines. Basically, some people are so surprised by the injections that their anxiety triggers a physical reaction.

“We know we are going to see this,”

; as numerous COVID-19 vaccine clinics have been established around the world. Noni McDonald, a Canadian researcher who studies similar events, said.

The CDC authors said the report ran over a three-day period from April 7 to 9 from clinics in California, Colorado, Georgia, Iowa and North Carolina. The investigation is based on interviews and reports by clinical staff.

Many of the 64 affected people either fainted or reported dizziness. Some people nausea or vomiting, and others have a heartbeat, chest pain, or other symptoms. No one is seriously ill.

All received the Johnson & Johnson vaccine and four of the five clinics have been temporarily closed as officials try to figure out what happened. Health officials at the time said they had no reason to suspect there was a problem with the vaccine itself.

Of the three COVID-19 vaccines licensed in the United States, only one dose of J&J is required. That could make it more attractive to people concerned about the image and may leave them “more prone to anxiety-related incidents,” the CDC report said.

Some websites advertise that they provide pictures of J&J, said Dr. Tom Shimabukuro, who is the CDC’s COVID-19 vaccine safety review supervisor and one of the study’s authors.

The CDC found that about a quarter of people who reported side effects had similar things following their vaccinations in the past.

Post-shot reactions differ from very rare side effects, leading to temporary discontinuation of J&J vaccine.At least 17 vaccine recipients developed abnormal blood clots that occurred in abnormal locations such as veins. That drains blood from the brain with abnormally low levels of platelets that form blood clots.

Other types of side effects from the coronavirus vaccine are not uncommon.Another CDC report published Friday looked at side effects reported by more than 300,000 J&J vaccine recipients, more than half said they had an aching arm. Fatigue or headache A third reported a fever or chills, and about one in five said they had nausea.

But the group at all five clinics believed that stress

MacDonald, a professor of pediatrics at Dalhousie University in Nova Scotia, said the study indicated that 10% to 15% of adults were afraid of injections.

Many people with stress-related symptoms were younger, and other visual past groups were involved with school students. Some people have nausea and vomiting, some have headache. And some people have more severe neurological symptoms at first, she said.

One cluster that MacDonald investigated involved 14 US military forces who had onset after being exposed to the flu in 2009.The first was 23-year-old men, who later reported continued weakness in their arms and legs. But fully recovered

“Everyone thought this was (only) a teenage girl” who had been exposed to it, MacDonald said.

It may start with a person’s fainting, which can trigger a chain reaction in an anxious person seeing or hearing about that first person. Nowadays, people still respond to what they read or see on Facebook posts or on other websites.

Some doctors refer to the phenomenon as a form of mass hysteria, but MacDonald rejects the term.

“These people are not crazy” but are experiencing a real physical response to psychological stress, she said.
