  1. 1Booster-only model consisted of post-third dose (n = 113), post-fourth dose (n = 26), and post-fifth dose (n = 3) serum samples. 2Hybrid immunity model consisted of post-third dose (n = 103), post-fourth dose (n = 42), and post-fifth dose (n = 15) serum samples with evidence of previous SARS-CoV-2 PVI.
