RESULTS: infants, there was no infant second year life, incident rate ratio (IRR) for seizures after receipt measles-mumps-rubella vaccine (MMR) dose at 12 15 months 2.65 (95% confidence interval [CI] 1.99–3.55); IRR an MMR 16 23 6.53 CI 3.15–13.53). The measles-mumps-rubella-varicella (MMRV) 4.95 3.68–6.66); MMRV 9.80 4.35 –22.06). CONCLUSIONS: There increased risk infants regardless vaccination. 2, delaying past age results higher strength doubled vaccine. These findings suggest that on-time as safe regard delayed life associated more than
