abstract = {Whether existing serological assays are sufficiently robust
to measure the lower antibody levels expected following
single-dose HPV vaccination is unknown.We evaluated seven
assays measuring HPV-16/18 immunological responses overall
and by number of doses in 530 serum samples from
participants receiving varying doses of Cervarix or Gardasil
up to 36-months post-vaccination. Serum was evaluated by
simplex (HPV-16 ELISA, HPV-18 ELISA), multiplex (LIA-4,
VLP-MIA, M9ELISA, GST-L1), and high-throughput
pseudovirion-based neutralization assays (HT-PBNA), and
results were compared to the gold standard HPV-16/18
secreted alkaline phosphatase neutralization assay
(SEAP-NA). Reproducibility was assessed by the coefficient
of variation (CV) and intraclass correlation coefficient
(ICC). Percent agreement, Pearson correlation, and
weighted-kappa were used to assess validity. Determinants of
seronegativity were evaluated by chi-squared test.HPV-16:
Seropositivity range was $97.1-99.5\%$ for single dose and
$98.8-99.8\%$ overall. CV range was $4.0-18.0\%$ for single
dose and $2.9-19.5\%$ overall. ICC range was 0.77-0.99 for
single dose and 0.74-0.99 overall. Correlation with SEAP-NA
range was 0.43-0.85 for single dose and 0.51-0.90 overall.
Weighted-kappa range was 0.34-0.82 for single dose and
0.45-0.84 overall. HPV-18: Seropositivity range was
$63.9-94.7\%$ for single dose and $86.2-97.9\%$ overall. CV
range was $8.1-18.2\%$ for single dose and $4.6-18.6\%$
overall. ICC range was 0.75-0.99 for single dose and
0.83-0.99 overall. Correlation with SEAP-NA range was
0.31-0.99 for single dose and 0.27-0.96 overall.
Weighted-kappa range was 0.35-0.83 for single dose and
0.45-0.84 overall. HPV-16 seronegativity was $<5\%$ for all
assays. HPV-18 seronegativity range was $5.5-17.3\%.$ For
LIA-4 and GST-L1 where the proportion of seronegativity was
$>10\%,$ the strongest correlates of seronegativity were
receiving a single vaccine dose and receiving Gardasil.These
results support the utility of existing serological assays
to monitor antibody responses following single-dose HPV
vaccination.},
