Table 3.

A binary logistic model (n = 111, Nagelkerke R² = 0.556, p < 0.0001) with willingness to be vaccinated for free being the dependent variable (“yes” = 1, “no” = 0).

Independent Variable (“Yes” = 1, “No” = 0)	Coefficient	p Value	Odds Ratio (95% Confidence Interval)
Vaccines are safe for most people and do not cause long-term side effects or complications	2.067	0.001 *	7.90 (2.43–25.74)
Vaccines may cause the infectious disease they target	−1.942	0.002 *	0.14 (0.04–0.49)
Vaccination is the only way to gain immunity apart from acquiring the disease itself	1.365	0.047 *	3.91 (1.02–15.05)
Vaccination is also useful for healthy people with no existing disease	1.072	0.153	2.92 (0.67–12.73)
There is a natural decrease of viral infections, regardless of the use of vaccines	0.538	0.399	1.71 (0.49–5.99)
Used to be vaccinated against influenza before the COVID-19 pandemic	−0.159	0.854	0.85 (0.16–4.65)
Vaccination against influenza in 2020	2.216	0.037 *	9.17 (1.15–73.47)
COVID-19 infection	−0.880	0.383	0.42 (0.06–2.99)
Constant	−3.032	0.001 *	0.05 (n/a)
