Ad5-EBOV Ebola Vaccine Description

Ad5-EBOV is an adenovirus type 5 vector-based Ebola virus disease vaccine that protects against Ebola by relying on the recombinant replication-defective human adenovirus type-5 vector immune response. 

The Ad5-EBOV is manufactured as a lyophilized powder, highly stable, and does not require storage at ultra-low temperatures. This feature renders it viable for use in resource-limited tropical areas

CanSino Biologics's Ad5-EBOV received approval in China in October 2017. 

In 2014, a single-center, double-blind, placebo-control, dose-escalation phase 1 clinical trial was performed in Taizhou, China. The findings showed that the Ad5-EBOV vaccine was safe and robustly immunogenic. The investigators intended to evaluate the safety and immunogenicity of a booster dose of the recombinant Ebola adenovirus vector vaccine (Ad5-EBOV) in healthy adults after primary immunization in this add-in study. The investigators expect that boosting immunization with the same vaccine for primary immunization is possible and could confer longer-lived protection when needed.

In July 2015, the First Affiliated Hospital of Zhejiang University launched a single-center, open, dose-escalation phase 1 clinical trial. This study will determine the safety and side-effect profile and immunogenicity of an investigational Ad5-EBOV vaccine in Healthy Adult Africans aged between 18-60 years in China.

Ad5-EBOV has shown an acceptable stability profile and does not require ultra-low temperature storage conditions.

CanSino Biologics Inc.'s Ad5-EBOV is currently for the national Chinese stockpile and can increase international stockpile opportunities.

Ad5-EBOV Ebola Vaccine Indication

Ad5-EBOV is indicated to prevent an infection of the Ebola disease. One shot of the high dose vaccine could mount a glycoprotein-specific humoral and T-cell response against the Ebola virus in 14 days.

The company says, 'As compared to competing products from multinational companies, our Ad5-EBOV has shown a better stability profile and does not require ultra-low temperature storage conditions.'
