Safety and Immunogenicity of 20-valent Pneumococcal Conjugate Vaccine According to Number and Timing of Primary Series Doses

Listen to this summary

This study investigates how the number and timing of primary doses of the 20-valent pneumococcal conjugate vaccine (PCV20) affect immune responses in infants. The analysis reveals that a 1-month delay in the priming doses from 2 and 4 months to 3 and 5 months results in stronger immune responses, comparable to those elicited by the 13-valent vaccine (PCV13). Overall, PCV20 was found to be safe and well tolerated across different dosing schedules.
