Are there no footnotes in Vancouver referencing?
This is correct. See the last page of this pdf for an example of a Vancouver references section:

In response to a comment below about the in-text citations coming after the punctuation, here is another example where they use brackets but don't mention if it is in-text citations (but the references section/end of essay references match the guide above). When I use Vancouver style in my own writing, Mendeley defaults in-text citations within the period.
