age cut off for varicella
Can be given to children for their routine two doses of chickenpox vaccine at 12 through 15 months old and 4 through 6 years old. Children who get the first dose of this vaccine at 12 to 23 months old may have a higher chance of a seizure caused by fever. This is in comparison to children who get the measles, mumps, and rubella vaccine and the chickenpox vaccine separately during a doctor visit.
