Immunogenicity & Safety of Bio Farma's Measles-Rubella (MR) Vaccine in Indonesian Infants (Bridging Study)

Phase 2

Completed

• Conditions: Measles; Congenital Rubella Infection

• Registration Number: NCT04183114
• Lead Sponsor: PT Bio Farma

Brief Summary

Thus study is a clinical trial for Measles and Rubella vaccine that will be used inIndonesian National Program of Immunization. The study design will be randomized, observer blind, prospective intervention study.

Detailed Description

The objectives of the study are:

* To assess the protectivity rate of Bio Farma's Measles/Rubella (MR) vaccine in infants

* To describe antibody response to Measles and Rubella after 1 dose of Bio Farma's MR vaccine as a primary dose in infants

* To assess the safety of Bio Farma's Measles/Rubella (MR) vaccine in infants

* To evaluate immunogenicity and safety one dose of Bio Farma's MR vaccine compare to registered MR vaccine.

* To evaluate immunogenicity and safety in three consecutive batches of Bio Farma's MR vaccine in infants .
