Varicella: previously healthy children sometimes develop complications

Three healthy boys, 3.5, 5 and 1.5 years of age, were admitted to hospital with a severe bacterial skin infection, cerebellar ataxia, and pneumonia, respectively, one week after the onset of varicella. They recovered completely after treatment. Studies in Europe report complications from varicella in 2.5% of healthy children. Most of these are neurological complications and secondary bacterial infections of skin and soft tissue. Last year, a European consensus was published that recommended that all healthy children be vaccinated against chickenpox. In The Netherlands, routine varicella zoster virus (VZV) vaccination has not (yet) been implemented. We propose a new discussion on the possible inclusion of VZV vaccination in the national vaccination programme.
