Nocebo underlies many Covid-19 vaccine negative side effects

So many of the reported negative side effects by people who received Covid-19 vaccinations are imaginary!

"Most of the side effects that people experience after a COVID-19 vaccination can be blamed on the ‘nocebo’ effect. The nocebo effect is like the evil twin of the placebo effect — for example, it heightens pain if a person anticipates that something will hurt. Researchers reviewed 12 randomized clinical trials of COVID-19 vaccines and found that the nocebo effect accounted for 76% of common adverse reactions, such as headache and fatigue, after the first dose. ..."

"Question  What was the frequency of adverse events (AEs) in the placebo groups of COVID-19 vaccine trials?

Findings  In this systematic review and meta-analysis of 12 articles including AE reports for 45 380 trial participants, systemic AEs were experienced by 35% of placebo recipients after the first dose and 32% after the second. Significantly more AEs were reported in the vaccine groups, but AEs in placebo arms (“nocebo responses”) accounted for 76% of systemic AEs after the first COVID-19 vaccine dose and 52% after the second dose.

Meaning  This study found that the rate of nocebo responses in placebo arms of COVID-19 vaccine trials was substantial; this finding should be considered in public vaccination programs."
