Safety and tolerability of the Japanese encephalitis vaccine IC51 (JE-PIV). Double blind, randomized, placebo controlled phase 3 study - IC51- 302

• Conditions: Japanese encephalitis (JE) is the most common viral encephalitis, with over 50,000 cases reported annually. It is a considerable public health problem for many Asian countries (WHO 1997). Close to 3 billion people now live in regions at risk for the disease, particularly in rural areas where JE occurs sporadically in epidemics of variable magnitude. Vaccination against JE remains the single most important control measure worldwide.
