Most important, though, is the question of transparency. Russia has published some information from its phase 1 and 2 studies for the Sputnik vaccine. Immediately after its first results were published, though, concerns were raised by a group of Western scientists, querying, for example, repeated patterns in the data that were not fully explained. Since, scientists from leading Russian universities have also asked for more information, further questioning methodology and data analysis. Even less is known about the second vaccine candidate. So too in China. The United Arab Emirates has said the Sinopharm vaccine showed 86% efficacy in Phase 3 tests, but more detail is required on side-effects and demographics. It could still receive China’s full approval later this month.
