Abstract:
For 4 consecutive years 1997-2000, immunization with Japanese encephalitis (JE) vaccine produced by the NIHE has been extended into the 90 high risk districts of the Northern region. 1.219.779 out of 1.296.248 children aged 1-5 years were immunized with two doses of JE vaccine, a total of 94.1% and 833.199 out of 878.643 children aged 1-5 years were also immunized with a booster dose achieving a coverage of 94.83%. There were no complications reported after JE immunization. Disease surveillance results in these districts showed that: the incidence of JE has decreased each year and from 1995 to 2000 the incidence was reduced 2.4 times.
