- Combining a Sputnik V shot with a dose of a different vaccine would address a shortage of the Russian product, says CanSino executive
- The trial is expected to start in August or September and although the location has not been disclosed, it will not be carried out in China or Russia
“[The combined use] is something that several countries have been asking for because the Russians have had difficulties in supplying the second dose in sufficient quantities compared to the first dose,” Morgon said.
He expected the trial to start around August or September. Morgon declined to disclose where the trial would be conducted because the information was yet to be made public, but he said it would not be in China or Russia.
Both Sputnik V and the CanSino shot are viral vector vaccines and use adenovirus engineered to be harmless as a vector to carry the coronavirus’ genetic information into the human body.
The first dose of Sputnik V is based on adenovirus type 26, while the second dose and the CanSinoBIO’s vaccine contain adenovirus type 5.
The trial, which will study the combined doses’ safety and ability to trigger immune response in adults, has obtained local authorities’ endorsement, pending approval from an ethical committee, said Morgon.
Clinical trials combining AstraZeneca-Oxford University’s Covid-19 vaccine,
which also uses a chimpanzee adenovirus vector, with Sputnik V had been approved in Russia, Azerbaijan, the United Arab Emirates and Belarus.
