This question is repeating a previous one but with a longer range of possible answers.
Russia has started vaccinating adults from the general population with the Sputnik V COVID vaccine in December 2020. As of June 2021, it is authorized for use in 66+ other countries including India and Brazil. However, as of July 2021 it is not approved by the World Health Organization in its emergency use listing (EUL). Approval by WHO is important, for example, for people vaccinated with Sputnik V if they want to study in US schools or travel in places that require you to be vaccinated with a WHO-approved vaccine.
As of July 26, 2021 WHO lists Pfizer, Moderna, 5 variants of AstraZeneca, J&J, Sinopharm and Sinovac as being approved for emergency use. Sputnik V is in the pipeline, with meetings held, but additional data is required.
When will the Sputnik V vaccine be approved by WHO?
The question resolves on the date when WHO approval for Sputnik V vaccine is granted for emergency use. If such as an approval is not granted, this resolves at the upper bound.
