A single blind randomized phase 3 study to evaluate safety and immunogenicity of inactivated hepatitis A vaccine (HAPIBEV) in 1-15 years-old healthy hepatitis A vaccine-naïve children.

The Biological E inactivated hepatitis A (HAPIBEV™) vaccine was developed by importing the Healive® vaccine bulk from China and fill-finish it in India. Healive® vaccine is approved in China for both children and adults. This study assessed the safety and immunogenicity of HAPIBEV™ vaccine as compared to the Havrix 720® vaccine of GlaxoSmithKline (GSK) pharmaceuticals when administered intramuscularly (IM) 6 months apart in 1-15 years old hepatitis A virus (HAV) vaccine naive children in India.

Immunogenicity and safety of IXIARO (IC51) in a Phase II study in healthy Indian children between 1 and 3 years of age.

For adults the standard administration of the Japanese encephalitis vaccine IXIARO is two injections of 6 microg in a 28-day interval. Immunogenicity and safety of 3 and 6 microg of IXIARO compared to JenceVac were investigated in 60 healthy Indian children aged between 1 and 3 years. JE specific neutralizing antibodies were measured at baseline and 28 days after the first and second vaccination.

Immune response to an indigenously developed r-hepatitis B vaccine in mixed population: study of an accelerated vaccination schedule.

Aim: To establish the safety and efficacy of an indigenously developed r-hepatitis B vaccine using an accelerated schedule and to highlight the social awareness and commitment in preventing the spreading of hepatitis B virus infection.

Methods: The study was a multicentric, double blind, randomized (3:1) study using three doses of vaccine immunization schedule (20 mug for those above 10 years old and 10 mug for those below 10 years old) on d 0, 30 and 60. One hundred and sixty-six subjects were enrolled (87 males and 76 females aged 5-35 years).
