Canadian and United States guidelines have different recommendations regarding the waiting time between an episode of shingles and vaccination.
Three months ago I developed shingles on my scalp. Several years before I had The Zostavax. The Shringrix was not available in my area. Upon researching recent shingles infections and Shringrix, I found that Canada recommends you do NOT get the vaccine until about a year after an active case of shingles. I think it has something to do with less efficacy. I wish I could remember where I saw this, I think the Canadian government website. I have asked several local pharmacists and they have no idea...get it right away, wait a couple of months, etc... Have you seen the Canadian information? I have looked for its again and can not locate the site. I cannot even find anything specific from the CDC.

The following is an excerpt from those guidelines:
