NCT01865968

Brief Summary

A phase IV, randomization, single center, controlled clinical trial to compare the safety, immunogenicity,three-year immune persistence of inactivated hepatitis A vaccine (HAV) with one- or two-dose regimen and live attenuated HAV with one-dose regimen in Chinese young adults, and to evaluate the immunogenicity of a booster dose.

Outcome Measures

Primary Outcomes (1)

  • concentration of antibody to hepatitis A virus

    Anti-HAV antibody geometric mean concentrations pre-vaccination, and at month 1, and 12, 24 and 36, and 1 months (month 37) after the booster vaccination.

    37 months

Secondary Outcomes (1)

  • reported side effects and adverse events

    37 months

Study Arms (3)

Inactivated HAV vaccine

EXPERIMENTAL

Healthy undergraduate students aged 16 to 25 years with anti-HAV negative received inactivated HAV vaccine containing 500u/vial with one-dose regimen.

Biological: Inactivated HAV vaccine

Live attenuated HAV vaccine

ACTIVE COMPARATOR

Healthy undergraduate students aged 16 to 25 years with anti-HAV negative received live attenuated HAV vaccine containing 6.50 lgCCID50/vial with one-dose regimen.

Biological: Live attenuated HAV vaccine

Two-dose inactivated HAV vaccine

EXPERIMENTAL

Healthy undergraduate students aged 16 to 25 years with anti-HAV negative received inactivated HAV vaccine containing 500u/vial with two-dose regimen.

Biological: Inactivated HAV vaccine

Interventions

Hepatitis A vaccine (Healive), 500 u per dose per 0.5 millilitre. Vaccines will be administered with one-dose or two-dose regimen of the arm 6 months apart in the deltoid muscle.

Also known as: Inactivated hepatitis A vaccines
