In Merck's study, its vaccine, Vaxneuvance, met key immunogenicity and safety endpoints for healthy infants aged 2-15 months, and its safety profile was similar to that of PCV13 after each vaccine dose. Vaxneuvance was found to be noninferior to PCV13 for all 13 shared serotypes at 30 days after the third dose based on serotype-specific response rates. On the basis of serotype-specific immunoglobulin G geometric mean concentrations, it was also noninferior to 12 of the 13 shared serotypes. After the fourth dose at 30 days, similar findings were reported.
