VAXNEUVANCE achieved robust immune responses during the first year of life and beyond

Immunogenicity against key disease-causing serotypes is important.1-3

In the absence of clinical efficacy endpoints, vaccine effectiveness against invasive pneumococcal disease may be inferred by comparing immunogenicity of pneumococcal conjugate vaccines to measure (or evaluate) noninferiority in clinical trials.4

The introduction of PCVs has been effective in reducing IPD in children. However, select serotypes—such as Serotype 3, 22F, and 33F—continue to contribute to the burden of disease.1,2

VAXNEUVANCE delivered a robust immune response against 15 serotypes postdose 3 as demonstrated by IgG response rates and postdose 4 GMC ratios, includinga:

  • Comparable immune responses for 12 shared serotypes found in PCV13
  • Superior immune responses for shared Serotype 3 vs PCV13b,c
  • Superior immune responses for unique Serotypes 22F and 33F—not covered by PCV135

Randomized controlled trials assessing the clinical efficacy of VAXNEUVANCE compared to PCV13 have not been conducted.

GMC Ratios, postdose 3a

After a 3-dose primary series, VAXNEUVANCE was found to be noninferior to PCV13 for 12 out of 13 shared serotypes based on the lower bound of the 2-sided 95% CI for the GMC ratio (VAXNEUVANCE/PCV13) being >0.5. For VAXNEUVANCE, the lgG GMC for serotype 6A was just below the noninferiority criteria by a small margin, with the lower bound of the 2-sided 95% CI for the GMC ratio being 0.48 compared to the required criteria of >0.5 for noninferiority.

Study design

Study 8 was a pivotal, double-blind, active comparator-controlled study in which participants were randomized to receive VAXNEUVANCE (N=860) or PCV13 (N=860) in a 4-dose series. The first 3 doses were administered to infants at 2, 4, and 6 months of age and the fourth dose was administered to children at 12 through 15 months of age. Participants also received other licensed pediatric vaccines concomitantly. Immune responses were measured by IgG response rates, IgG GMCs, and OPA GMTs for all 15 serotypes contained in VAXNEUVANCE.

CI, confidence interval; GMC, geometric mean concentration (mcg/mL); GMT, geometric mean titer; IgG, Immunoglobulin G; IPD, invasive pneumococcal disease; OPA, opsonophagocytic activity; PCV, pneumococcal conjugate vaccine; PCV13, 13-valent pneumococcal conjugate vaccine.
