We investigated immediate immunization pain in 12-month-old children randomized to receive a booster dose of either the 10- (PCV-10) or the 13-valent (PCV-13) pneumococcal conjugate vaccine. Pain was assessed using validated pain assessment tools and crying time. PCV-13 recipients had significantly higher scores on the observer-rated modified behavioral pain scale than did those receiving PCV-10, but the differences were small.
