RDIF), which promotes Sputnik V abroad, said a group of WHO inspectors is due to visit Russia shortly "to round up all necessary inspections and paperwork on Sputnik V." Separately, Kirill Dmitriev, the RDIF head, told CNN he expected the WHO to approve Sputnik V in coming months, RIA news agency reported.
The WHO said in July its review of how Russia produces the Sputnik V vaccine had found some issues with the filling of vials at one plant.
The manufacturer said it had since addressed all of the WHO's concerns. RDIF has funded COVID-19 testing systems, drugs and vaccines.
RDIF supports the development of the Sputnik V vaccine by the Gamaleya Center and is investing in mass production of the vaccine.
