Oh, cool, another "Venn Diagram Slice" I didn't even think of.
To repeat, I think it's a very, very tiny slice of the Convoy that hates mandates but totally accepts all vaccines themselves.
I suspect, of the very large slice that is not just mandate-hating, but won't take the vaccine itself, well over half won't accept any vaccine at all, whereas well under half are only concerned about the COVID vaccines. By the time the convoy rolled, there were also "good 'ol fashioned" vaccines like Novavax and Johnson&Johnson, but I didn't see a single sign or protester comment that indicated they were waiting for the "right" vaccine to come along. Every interview devolved into general anti-vax complaints, with not one of them distinguishing between different types or brands.
If you could provide a link to such an interview, or pictures of protesters with brand-related concerns about only the new vaccines, please educate us.
