To help prevent pediatric IPD, protect against what matters, when it matters, with VAXNEUVANCE® (Pneumococcal 15-valent Conjugate Vaccine)1,2
Deliver robust and early immunogenicity against critical serotypes during the first year of life and beyond.1
VAXNEUVANCE is administered as a 4-dose series at 2, 4, 6, and 12 through 15 months of age.
Choose VAXNEUVANCE for your pediatric patients

IPD protection against key disease-causing serotypes matters.1

IPD protection during the first year of life matters, when the threat of IPD is highest.2-6

VAXNEUVANCE delivers superior immune responses for critical IPD-causing Serotypes 3, 22F, and 33F and comparable immune responses for 12 shared serotypes.1,7,a-e

VAXNEUVANCE is a CDC, AAP, and AAFP recommended conjugate vaccine option for your pediatric patients.6,8,9
VAXNEUVANCE was studied vs PCV13.
Randomized controlled trials assessing the clinical efficacy of VAXNEUVANCE compared to PCV13 have not been conducted.
No randomized controlled clinical trials have been conducted between PCV20 and VAXNEUVANCE in pediatric patients.10
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.
aMeasurements were taken 30 days postdose specified.
bSecondary endpoint: Postdose 3 IgG response rate percentage point difference vs PCV13 (95% CI): for Serotype 3, 19.1 (14.4, 24.0); for Serotype 22F, 8.1 (5.1, 11.5); for Serotype 33F, -5.1 (-9.5, -0.7).11
cSecondary endpoint: Postdose 4 IgG GMC ratio vs PCV13 (95% CI): for Serotype 3, 1.43 (1.30, 1.57); for Serotype 22F, 4.77 (4.28, 5.32); for Serotype 33F, 2.68 (2.40, 3.00).11
dSecondary endpoint: Postdose 3 lgG GMC ratio vs PCV13 (95% CI): for Serotype 3, 1.70 (1.54, 1.86).11
eThe 12 shared serotypes were ST1, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F.11
