I don't think nurses have much (any) training in biotech. An MD might have a 4-year undergrad in biochemistry or molecular biology or something, an internship at a biotech company or time in a research lab, they might be on one or two wetlab publications, they have another 4 years of medical training with lab experience for the MD, and another 3 or more years in residency training. I believe most nurses have only an associates (2-year), or a 4-year undergrad degree with zero lab experience, zero biotech industry experience, and zero research-focused biochemistry/molecular biology/immunology training. They're not out there running ELISAs, Western Blots, minipreps and passaging cell cultures. So they may not understand how the vaccine technology works at a particularly higher level than the general public. Not a slight against nurses, of course, they do incredibly valuable work. But, upon hearing about a novel mRNA-based vaccine technology, they may be less likely than, say, an MD or a biomedical PhD to go 'that's a pretty cool application of a technology I understand pretty well." Same thing with cops, fire, paramedics etc. They didn't exactly spend a decade in school to learn all about the magic of B cells and epitopes. So, they might be a little suspicious of something they're not exactly trained to understand, and seemingly not particularly curious about. Not really their fault I guess, it's just way outside of their wheelhouse. In this particular situation, however, that becomes a bit of a problem since the public isn't necessarily able to contextualize their opinion on something, and may miss the fact that they may have zero clue what they're talking about. Agreed. Weird time to be alive indeed.
