    "What do they exactly mean by "registered"" <- This means this is off-topic. A skeptic question is supposed to be about empirical facts and not about word interpretation.

    @Christian I'm surprised to see that you just focused on a little drop of water in an ocean. However, my question isn't about that! It's just a secondary thing. Feb 10, 2021 at 20:03

    I think Christian's question/critique is very valid. This isn't really framed as a very good skeptical questions. Feb 10, 2021 at 20:13

    @Christian The job of a question is to question the validity of a notable claim. I see two patterns on Skeptics when the claim itself is ambiguous: the asker provides some narrower interpretation of the claim that they are asking about OR the answerer clarifies the interpretation of the claim that they are responding to. I do not see anything in the Skeptics rules or FAQ indicating that the asker is required to provide the clarification.

It is indeed the first registered vaccine. But the registration process in Russia is different than in other countries (say, USA). They basically skipped the third stage: testing the vaccine on a large number of humans. So the vaccination which is happening in Russia can be viewed as the third phase of testing. Thus even though it was registered first, it could not be viewed as thoroughly tested, at least till a few days ago.
