The decision to launch a joint clinical trial of British-Swedish-Russian vaccines, which was put on hold in May, became public on Monday. In the trial, which runs until March 2022, 150 volunteers will be vaccinated with the two vaccines and then observed to develop an immune response in their bodies. The program will include five health institutions in Moscow and Saint Petersburg – Writes A euronews.
Russian researchers involved in developing Sputnik V came up with the idea for a joint trial of the two vaccines in November, believing that this could increase the effectiveness of the vaccines.
AstraZeneca also announced such an attempt in December.
Sputnik V reported on Twitter that studies on the use of a vaccine mix like this one are also underway in Azerbaijan, Argentina and the United Arab Emirates.
The Sputnik V and AstraZeneca vaccines use the same technology: they use harmless adenoviruses as a vector to introduce the viral spike protein into the human body, which then triggers an immune response.
