Protection matters including in the first year of life when pediatric IPD incidence is highest1-4
IPD incidence in children in the US during the first year of life was >2x that of children 1-4 years of age, per a 2018-2021 pooled analysis3,a
IPD incidence in children in the US from a 2018-2021 pooled analysis3,a
aThe CDC’s ABC surveillance areas for Streptococcus pneumoniae included 10 states from 2018-2021, representing more than 34 million persons per year. During that period, there were 161 cases of IPD reported in infants less than 1 year of age, 134 cases in children 1 year of age, and 164 cases in children ages 2 to 4. Data for 2020 may have been impacted by associated mitigation measures implemented during the COVID-19 pandemic.3,5
VAXNEUVANCE is administered as a 4-dose series at 2, 4, 6, and 12 through 15 months of age.
Key effects of common IPD types
Pneumococcal Meningitis
- About 1 in 12 children die of the infection7
- Survivors may have lifelong disabilities, such as hearing loss or other neurological complications7
Pneumococcal Bacteremia
- The most common type of IPD in children under 2 years of age1,7,b
- About 1 in 30 affected children will die7
bWithout a known site of infection.1
Recommended PCV dosing
PCVs are recommended as a 4-dose series. Children wait 6-9 months after the third dose until they are able to receive the fourth dose.8
Despite this recommendation, about 1 in 6 toddlers receive 3 or fewer of the 4 doses of PCV by 2 years of age.8,9,c

ABC, Active Bacterial Core; ACIP, Advisory Committee on Immunization Practices; CDC, Centers for Disease Control and Prevention; IPD, invasive pneumococcal disease; NIS-Child, National Immunization Survey – Child; PCV, pneumococcal conjugate vaccine.
The immune response generated postdose 3 is an important measure when evaluating protection against IPD during the first year of life.8,10,11
