The mRNA covid vaccine nasal trials are going very well, so I would assume a similar influenza vaccine might fare just as well. As to the why, there are few barriers to getting a flu shot, but these barriers definitely cut down on vaccination rates. If you take needles out of the equation, the whole thing becomes easier. Heck, I could see people being able to self administer a nasal spray.
