Moreover, an intranasal vaccine wouldn't require a syringe, cutting both cost and medical waste, nor would it likely necessitate an administering health care professional, writes Stat. Plus, an intranasal inoculation is usually easier to offer to young kids and those with a fear of needles.
All that said, the development of such a tool might be far off. It's not yet clear if the mRNA vaccines could be reformulated, and an intranasal candidate is likely to be a "next, next, next-gen vaccine," adds Florian Krammer, a vaccinologist at the Icahn School of Medicine at Mount Sinai Hospital. Funding is reportedly also an issue.
