Fig. 3: HPV antibody signature in unvaccinated and vaccinated Fijian girls.

The polar plots depict the relative magnitude of HPV16 and HPV18 antibody features six years following the last dose of 4vHPV vaccine (Pre) or 28 days post-2vHPV booster (Post). Wedge sizes represent the median of each antibody feature, normalised within HPV genotypes and antibody features, and across all dose groups; 0-dose (n = 20), 1-dose (n = 20), 2-dose (n = 21), 3-dose (n = 19).
