20-valent Pneumococcal Conjugate Vaccine Safety and Immunogenicity Study in Healthy Japanese Infants

Phase 3
Completed
Conditions
Prevention of Pneumococcal infection
Registration Number
JPRN-jRCT2080225365
Lead Sponsor
Pfizer R&D Japan G.K.
Brief Summary

20vPnC SC had a similar tolerability and safety profile to 13vPnC SC. The 4-dose series of 20vPnC SC elicits immune responses that are expected to expand protection against pneumococcal disease due to the 7 additional serotypes, while maintaining existing protection currently controlled by 13vPnC in Japanese infants. The 2 modes of administration had a similar safety and tolerability profile except for injection site swelling and redness, which were lower in 20vPnC IM.
