@ parisiosFor children age two and younger, the MMRV vaccine is associated with more adverse events compared to separate administration of MMR and varicella vaccinations on the same day. There are 4.3 additional febrile seizures per 10,000 vaccinated children (95% CI 2.6–5.6), 7.5 additional mostly mild fever episodes per 100 vaccinated children (95% CI, 5.4–9.4) and 1.1 additional measles-like rash per 100 children (95% CI, 0.2–1.8). Febrile seizures cased by the MMRV vaccine occur 7 to 10 days after vaccination. In children age 4–6, there is no evidence for an increased risk in febrile seizures after MMRV compared to the separate administration of MMR and Varicella vaccines.Οπότε, ναι, έχουν παρατηρηθεί 4,3/10.000 παραπάνω περιστατικά πυρετικών σπασμών σε ηλικίες 2 και κάτω.
