Help protect your youngest patients against critical IPD-causing serotypes1
VAXNEUVANCE elicited superior immune responses vs PCV13 for shared Serotype 3 and unique Serotypes 22F and 33F through the first year of life and beyond*
In 2010, PCV13 introduced routine pediatric coverage against Serotype 3.2,3 According to a pooled analysis from 2018-2021, Serotypes 3, 22F, and 33F were three of the top six IPD-causing serotypes in children under 5 years.1,a,b
Additionally, Serotypes 3, 22F, and 33F can cause significant IPD-related morbidity in children and are associated with varying degrees of antimicrobial resistance.4-6
VAXNEUVANCE is administered as a 4-dose series given at 2, 4, 6, and 12 through 15 months of age.
*Randomized controlled trials assessing the clinical efficacy of VAXNEUVANCE compared to PCV13 have not been conducted.
In a pooled analysis from 2018-2021, ~1 in 4 cases of IPD in children under 5 years of age were caused by the following serotypes1,a,b:
aFrom 2018-2021, the top 6 IPD-causing serotypes in children under 5 years were 15C, 33F, 19F, 3, 23B, and 22F.
Serotypes 15C and 23B are not included in any pediatric PCV in the US.1,3,7,8
bThe CDC noted that historic decreases of IPD burden in 2020 were likely due to the associated mitigation measures implemented during the COVID-19 pandemic, as documented by the Active Bacterial Core (ABC) surveillance data.9
VAXNEUVANCE provided superior immune responses for shared Serotype 3 vs PCV13 postdose 3 and 4*
Superior IgG response rate for shared Serotype 3 vs PCV13
Postdose 3 (primary series)
IgG response rate percentage point difference (VAXNEUVANCE-PCV13), 19.1 (95% CI: 14.4, 24.0).
Superior IgG GMC Ratios for shared Serotype 3 vs PCV13
Postdose 3 (primary series)
lgG GMC Ratio vs PCV13, 1.70
(95% CI: 1.54, 1.86).
Superior IgG GMC Ratios for shared Serotype 3 vs PCV13
Postdose 4 (booster dose)
lgG GMC Ratio (VAXNEUVANCE/PCV13),
1.43 (95% CI: 1.30, 1.57).
*Randomized controlled trials assessing the clinical efficacy of VAXNEUVANCE compared to PCV13 have not been conducted.
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.
