If I understand correctly, the Planck Collaboration in this instance is exactly those hundred-something people listed in the paper, so
author = {{Planck Collaboration} and Y. Akrami and ...}
is not strictly speaking correct. It would be either
author = {{Planck Collaboration}}
or
author = {Y. Akrami and ...}
I can see how each of those solutions is not perfect: If you give only the group name, you effectively deny the people their name in the citation (although you would not give all hundred odd names anyway, so only about three out of 120 people will be mad at you, that is quite a good overall score). But if you cite only the people, the collaboration name, which is probably more widely known, will not be mentioned.
Unfortunately, biblatex and BibTeX have no notion of "a group consisting of ..." - you can either list the group name, or each member individually.
In this case you might be able to get away with
shortauthor = {{Planck Collaboration}}
but note that while the citation will look as expected, the bibliography entry will still have an incorrect "and" or "et al." if you use author = {{Planck Collaboration} and Y. Akrami and ...}.
I guess it would be ideal if you could put all individual names into the author field and the collaboration name into shortauthor. You would then have to convince your bibliography style to show both the shortauthor (collaboration name) and author (individual names) in the bibliography. Off the top of my head I know of no style that does this by default, but the modifications necessary to make biblatex do this are not too involved.

The term "Vancouver style" or "Vancouver system" seems to be slightly more variable than say, APA style or Chicago style. Often institutions have their own modifications to the general idea of the style. (Much like "Harvard style" often just means an author year style.)
According to Wikipedia the home of the "official Vancouver style" is the NLM's Citing Medicine.
From what I can see there, it is essentially a numerical style.
For BibTeX there is
vancouver.bst.For
biblatexa quick search on the web only turned up https://github.com/fluffels/biblatex-vancouver, the styles there haven't been updated in years though and the redefinitions of the drivers are indeed quite rough. See also Vancouver citation style in LaTex.I think your best bet with
biblatexis to start from anumericstyle and modify it as needed. One prominent feature is the name format which can be reproduced withterseinits=true, firstinits=trueandAs Johannes_B points out in the comments, there is Biblatex style file for New England Journal of Medicine (NEJM) which lead to
biblatex-nejm. And indeed what Marco Daniel implements there seems quite close to the Vancouver style requirements linked to above.The package has been last updated in November 2011 though, and so some of the code might not work that smoothly. From what I could see most of it is still absolutely the right code for the job. The
\renewbibmacro*{name:last-first}block, however, can be replaced by the code above.
