U.S. health officials have concluded that it was anxiety and not a problem with the vaccines that caused a range of symptoms including, dizziness, fainting and other reactions in dozens of people at coronavirus vaccine clinics in five states, according to U.S. health officials, Associated Press reported.
Anxiety, Not Vaccines Caused Symptoms In People: Health Officials
According to experts, the clusters, the Centers for Disease Control and Prevention identified formed an example of a phenomenon that had been documented over decades from different vaccines. Basically, the symptoms were a physical manifestation of their anxiety.
According to Dr Noni MacDonald, a Canadian researcher who had studied similar incidents, they would be seeing it, with mass Covid-19 vaccine clinics being set up all over the world.
According to the CDC authors the reactions were reported over three days, April 7 to 9, from clinics in Iowa, Colorado, California, Georgia and North Carolina. Reports and interviews with the clinic staff formed the basis of the investigation.
The 64 people who reported symptoms mostly suffered dizziness or fainting, while some vomited or had nausea. Chest pains and racing hearts were also reported by a few. None had taken seriously ill but some other symptoms were also reported.
All had been administered the Johnson & Johnson vaccine. The clinics were shut down temporarily as officials tried to figure out what was happening. According to health officials at the time, they had no reason to suspect any issue with the vaccine.
J&J vaccine is the only one of the authorized Covid-19 vaccines that required only one dose, which probably made it more appealing to people who were nervous and suspected that the shots leave might leave them more susceptible to anxiety-related events, according to the CDC report.
According to Dr Tom Shimabukuro, leader of the CDC’s Covid-19 vaccine monitoring work, a number of sites advertised administering J&J shots. Shimabukuro is also one the authors of the study.
The CDC found that about a quarter of the people reporting side effects had similar things happen following past vaccinations.
The post-shot reactions differed in respect of a side effect that was seen to be very rare, and which forced the administration to pause the J&J shot. An uncommon type of blood clot was seen in at least 17 vaccine recipients. The clots developed in unusual places, including veins draining blood from the brain, with abnormally low levels of the platelets forming the clots.
Other types of side effects of the vaccine were not unusual. These were discussed in another CDC report released Friday which considered side effects reported by over 300,000 recipients of the J&J vaccine. Over half reported fatigue, headache or a sore arm, while a third reported chills or fever, and about a fifth reported feeling nauseous.
The clusters at the clinic, though, were believed to be related to stress.
According to MacDonald, a pediatrics professor at Dalhousie University in Nova Scotia, studies had indicated that 10% to 15% of adults were scared of injections.
