Ọmụmụ Harvard: Ọgwụ mgbochi COVID-19 'mmetụta dị n'uche gị

After scrutinizing the reports of more than 45,000 clinical trial participants, Ụlọ Akwụkwọ Ahụike Harvard researchers said that the bulk of the Ọgwụ mgbochi covid-19 ‘side effects’ that people claim to experience after the jab, caused by people’s expectations and not by the vaccines.

Many people are so worried about Ọgwụ mgbochi covid-19 ‘side effects’ they actually feel them even if they get placebo, new research shows.

Various ‘systemic’ side effects, such as headaches, tiredness, and joint pain were reported in both halves of the research group: by those who received various COVID-19 vaccines, and by those who unknowingly received placebo. 

After analyzing the reports, scientists from the Boston-based Bet Israel Deaconess Medical Center came to the conclusion that the so-called ‘nocebo effect’ – unpleasant sensations caused by anxiety or bad expectations – accounted for three quarters of all reported vaccine side effects.

The report, which was published in the JAMA Network Open journal, says that 35% of placebo recipients reported side effects after the first dose and 32% after the second one. Significantly more “adverse events” (AEs) were reported in the vaccine groups, but so called “nocebo responses” accounted for “76% of systemic AEs after the first Ọgwụ mgbochi covid-19 dose and 52% after the second dose.”

The scientists note that, although the reasons for vaccination hesitancy are “diverse and complex,” concerns about potential side effects from the Ọgwụ mgbochi covid-19 “seem to be a major factor” and “public vaccination programs should consider these high nocebo responses.”

Otu n'ime Ụlọ Akwụkwọ Ahụike Harvard professors involved in the research, explained the science behind the “nocebo effect,” pointing out that “nonspecific symptoms,” such as headache and fatigue, are listed in many information booklets as typical side effects of COVID-19 vaccines.

“Evidence suggests that this sort of information may cause people to misattribute common daily background sensations as arising from the vaccine or cause anxiety and worry that make people hyper alert to bodily feelings about adverse events,” he said.
