This study is designed to evaluate the safety, tolerability, and immunogenicity of two different lots of V114 in healthy infants 6 to 12 weeks (>=42 days to <=90 days) of age.

The primary hypothesis of the study is that the proportion of participants receiving V114 who have serotype specific IgG >=0.35 mcg/mL for each of pneumococcal serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F at 1 month after Dose 3 is non-inferior to that for recipients of Prevnar 13™.


The Pediatric Infectious Disease Journal published the results of the clinical trial in August 2020.

Overall, 1044 of 1051 randomized infants received ≥1 dose of vaccine (V114 Lot 1 [n = 350], V114 Lot 2 [n = 347] or PCV13 [n = 347]). Adverse events were generally comparable across groups. At PD3, both V114 lots met noninferiority criteria for all 13 serotypes shared with PCV13. IgG GMCs were comparable among V114 and PCV13 recipients at PD3 and PD4. Serotype 3 responses were higher following receipt of V114 than PCV13. Both V114 lots induced higher GMCs than PCV13 to the 2 unique V114 serotypes.


Immunogenicity of both V114 lots was non-inferior to PCV13 for all 13 shared serotypes between the 2 vaccines and displayed comparable safety and tolerability profiles to PCV13.
