Summary of the correlation between the relative search volumes (RSV) from Google TrendsTM on tick-borne encephalitis (Italian: “encefalite da zecche”) and the probability of contracting a TBEV infection (Einf); perceived probability of developing complications after the delivery of TBE vaccine (Evac); perceived severity of a natural infection from TBEV (Cinf); perceived severity of vaccine side effects (Cvac); risk perception score regarding TBEV infection (RPSinf), and risk perception score regarding the TBE vaccine (RPSvac), as reported by 942 participants (Italy, 2023) (Note: 95%CI = 95% confidence interval). Google TrendsTM is an open-access online tool, provided by Alphabet, reporting the overall queries on a certain keyword as the normalized ratio over the total of web queries in that specific timeframe.
