Field efficacy trial of inactivated hepatitis A vaccine among children in Thailand (an extended abstract)

The Norwegian population is basically seronegative regarding anti-hepatitis A antibodies. For this reason they are particularly vulnerable when esposed to hepatitis A virus when staying in highly endemic areas. Norwegian UN-personnel have so far been protected with serum immunoglobulins (Ig). Two studies are reported, one followed a schedule of 0, 1 and 2 months with a booster at month 12, while the other followed a schedule of day 0 and 14 with a booster at month 7
