“…Among others, we found that pregnant women who received a flu vaccine had also a greater probability to be vaccinated against the COVID-19. Systematic reviews have already shown that previous seasonal influenza vaccination history is a strong predictive factor for individuals to accept a COVID-19 vaccine, both for themselves and their children (Galanis, Vraka, et al, 2021; Galanis, Vraka, Siskou, Konstantakopoulou, Katsiroumpa, & Kaitelidou, 2022a; Li et al, 2021; Luo et al, 2021; Shamshirsaz et al, 2021). Moreover, recent studies expand this evidence by confirming that COVID-19 vaccination uptake is more common among individuals that are already vaccinated against the seasonal influenza (Doran et al, 2022; Galanis, Moisoglou, et al, 2021; Galanis, Vraka, Siskou, Konstantakopoulou, Katsiroumpa, Moisoglou, et al, 2022; Gilboa et al, 2021; Shariff et al, 2022).…”
