Paracetamol use was significantly associated with reduction of
fever ≥38°C in children receiving the infant vaccine doses (2,
3, and 4 months), with a computed efficacy of 43% (95% CI
17.4 and 61.2), whereas use was not statistically significant for
the toddler dose (11-14 months) (efficacy 15.9%; 95% CI −19.9
and 41.3).
