World Health Organization approves 11th COVID-19 vaccine allowing emergency use listing for the vaccine Convedecia, a CanSino Biologics Vaccine.

This vaccine was approved after being carefully reviewed earlier this month by the Strategic Advisory Group of Experts on Immunization (SAGE) which is responsible for recommendations and specific policy-making regarding vaccines among populations.

Convadecia vaccine is a modified form of human adenovirus that is recommended for being used in patients who are above 18 years of age. This modified virus expresses the spike S protein of coronavirus in a single dose. According to WHO, the efficacy of this vaccine is 64% and 92% against symptomatic and severe COVID-19 disease.


Approval of the CanSino vaccine enriches the “growing portfolio of COVID-19 vaccines validated by WHO for the prevention of Covid-19 caused by SARS-CoV-2”. Previously, the CanSino shots were approved for emergency use by several nations including Indonesia, Pakistan, Hungary etc.

In an official press release WHO states “The Technical Advisory Group for Emergency Use Listing, convened by WHO and made up of regulatory experts from around the world, has determined that the vaccine meets the WHO standards for protection against COVID-19 and that the benefits of the vaccine far outweigh risks”.

Before this, ten other COVID vaccines were approved including AstraZeneca/Oxford, Covexin, Covishield, Covovax, Johnson and Johnson, Moderna, Nuvaxovid, Pfizer/BioNTech, Sinopharm and Sinovac.
