“…Eight studies were cohort studies (Blakeway et al, 2022; Goldshtein et al, 2022; Lipkind et al, 2022; Razzaghi et al, 2021; Rottenstreich et al, 2022; Stock et al, 2022; UK Health Security Agency, 2021; Wainstock et al, 2021) and three studies were cross-sectional (Hosokawa et al, 2022; Siegel et al, 2021; Taubman – Ben=Ari et al, 2022). Two studies used national data (Stock et al, 2022; UK Health Security Agency, 2021), three studies used a convenience sample (Hosokawa et al, 2022; Siegel et al, 2021; Taubman – Ben=Ari et al, 2022), and six studies did not report the sampling method (Blakeway et al, 2022; Goldshtein et al, 2022; Lipkind et al, 2022; Razzaghi et al, 2021; Rottenstreich et al, 2022; Wainstock et al, 2021). Ten studies were published in peer-reviewed journals (Blakeway et al, 2022; Goldshtein et al, 2022; Hosokawa et al, 2022; Lipkind et al, 2022; Razzaghi et al, 2021; Rottenstreich et al, 2022; Stock et al, 2022; Taubman – Ben=Ari et al, 2022; UK Health Security Agency, 2021; Wainstock et al, 2021) and one study in a pre-print service (Siegel et al, 2021).…”
