Russian officials claim they are working toward August 10 or earlier for approval of the vaccine. The WHO has not yet approved the vaccine.
As per the latest update from the World Health Organisation (WHO), the adenoviral vector-based vaccine developed by Russian military and government researchers is currently in phase 2 trials. Six other vaccine candidates are in the final phase of the testing.
On July 05, The Hindu cited Soumya Swaminathan, Chief Scientist at the World Health Organization, saying that a realistic (but very optimistic) timeline from the start of Phase-1 to the completion of Phase-3 could be about six to nine months (if all goes exactly according to plan).
Russia did announce on approving a vaccine for widespread use, but the safety and efficacy of it have not yet been determined. As per the WHO, Russia is still in Phase 2 of vaccine development and require time and further trials to produce a safe vaccine.
