Most Covid vaccine ‘side effects’ not caused by vaccines – study – Reuters Many people are so worried about the ‘side effects’ of the Covid vaccine that they experience them even if they receive a placebo, according to new research The vast majority of Covid vaccine ‘side effects’ are caused by people’s expectations rather than the vaccine, according to researchers at Harvard Medical School, after analyzing reports from more than 45,000 trial participants. Various “systemic“Side effects, such as headaches, fatigue and joint pain were reported in both halves of the focus group: among those who received various Covid vaccines, as well as those who received a placebo without the know. After analyzing the reports, scientists at the Boston-based Beth Israel Deaconess Medical Center came to the conclusion that the so-called “wedding effect— unpleasant feelings caused by anxiety or bad expectations — accounted for three-quarters of all reported vaccine side effects. The report, which was published in the journal JAMA Network Open, says 35% of placebo recipients reported side effects after the first dose and 32% after the second. Significantly more”adverse events(AE) have been reported in the vaccinated groups, but supposedlynocebo answers“counted”76% of systemic AEs after the first dose of Covid-19 vaccine and 52% after the second dose.” The scientists note that although the reasons for vaccine hesitancy are “diverse and complex,“concerns about potential side effects of Covid-19 vaccines”seems to be a major factor” and “public immunization programs should take these elevated nocebo responses into account.” One of the scientists involved in the research, Professor Ted Kaptchuk of Harvard Medical School, explained the science behind the “wedding effect.“He pointed out that”non-specific symptoms“, such as headaches and fatigue, are listed in many information leaflets as typical side effects of Covid vaccines. “Evidence suggests that this type of information may cause people to mistakenly attribute common daily background feelings as resulting from the vaccine or cause anxiety and worry that makes people hyperattentive to bodily feelings about adverse events. .Kaptchuk said.
