  Purpose

700 male and female healthy school-children (age 5 to 8) in Thailand were randomized to receive 2 or 3 primary rabies vaccine doses (PCECV, Rabipur) given intradermally in a dose of 0.1mL into the skin in the deltoid region. In a subset of 100 children blood was taken for rabies virus neutralizing antibody determination on day 49. All subjects were randomized to receive 2 booster doses (the recommended vaccination schedule for pre-immunized individuals in case of an exposure) on days 0 and 3, one, three or five years later. Blood was taken before and after booster for up to one year.Safety and tolerability of the vaccine was assessed and persistence of immune response up to 1 year after the booster doses.

Primary Outcome Measures:
  • rabies virus neuralizing antibody, assessed by RFFIT [ Time Frame: seven days after the first booster dose ] [ Designated as safety issue: No ]
    rabies virus neuralizing antibody concentrations were measured in serum samples using the rapid fluorescent focus inhibition test (RFFIT)


Secondary Outcome Measures:
  • rabies virus neuralizing antibody, assessed by RFFIT [ Time Frame: one year after the first booster dose ] [ Designated as safety issue: No ]
    rabies virus neuralizing antibody concentrations were measured in serum samples using the rapid fluorescent focus inhibition test (RFFIT)

  • rabies virus neuralizing antibody, assessed by RFFIT [ Time Frame: immediately before administration of the first booster dose ] [ Designated as safety issue: No ]
    rabies virus neuralizing antibody concentrations were measured in serum samples using the rapid fluorescent focus inhibition test (RFFIT)
