The way in which the childhood influenza vaccine is perceived has a strong connection with uptake, intended uptake and opinion of side effects, according to a recent study published in Vaccine.
“Although acute symptoms are common following many vaccinations, their causes are not always straightforward,” Louise E. Smith, PhD, and colleagues wrote. “While some may be directly attributable to vaccination, others may reflect pre-existing or coincidental symptoms that are misattributed to the vaccine, while still others may occur due to a ‘nocebo’ effect triggered by a self-fulfilling expectation of symptoms. Expectations may be caused by seeing someone else experience symptoms after vaccination or through exposure to information suggesting that side effects are common.”
