Right, but are there any vaccines out there that protect against disease but don’t prevent transmission? I thought that’s what herd immunity was all about.

You're asking if there are vaccines that do not lead to sterilizing immunity? Yes.

As per the article, the flu vaccine looked at didn’t provide sterilizing immunity, but did significantly lower viral titre in the lungs.

So I guess the question is - even if not sterilizing immunity, would these vaccines significantly reduce (but not eliminate) transmission?
