Reason for some side effects after Covid vaccine: Nocebo reaction

According to scientists, this is caused by effects known as “Nocebo reactions”, meaning that negative expectations affect the person negatively. Experts from Boston-based Beth Israel Diabetes Medical Center found that known Kovid vaccine side effects, such as headache, fatigue, and joint pain, are also observed when a placebo drug, also known as a “sugar drug”, which has no medical feature, is vaccinated instead of the vaccine.

systemic side effect

According to the study published in the journal JAMA Network Open, quoted by Sputnik, 35 percent of the 45,000 subjects who were given a placebo vaccine reported feeling the vaccine side effects after the first dose, and 32 percent after the second dose. While significant side effects were reported in the vaccine group, nocebo responses were seen in 76 percent of systemic side effects after the first Kovid-19 vaccine dose and 52 percent of side effects after the second dose in the non-vaccine group. Placebo means a positive result with a positive expectation in an ineffective drug intake; The nocebo effect occurs when a person is negatively influenced by their negative expectations about a situation. It was stated that scientists can increase the application of the Kovid-19 vaccine by raising awareness about the nocebo effect in order to reduce concerns about the side effects of the vaccine, reducing the concerns that make some people hesitate.
