Coronavirus: China’s CanSino to pair its vaccine with Russia’s Sputnik V in trial
- 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
Combined dosage may help address a global shortage of the two-dose Sputnik V, which adopts a similar technique as the Chinese company’s product, said Pierre Morgon, senior vice-president at CanSinoBIO.
“[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.
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.
