I've been hearing a lot about a new type of vaccine called a'single-dose' flu shot. Is this a good thing or a bad thing?

It depends on your perspective. If you're looking to protect yourself from the flu, then it can be seen as a positive thing because it's easier to get vaccinated and there are fewer side effects than with traditional vaccines. However, if you're worried about the safety of vaccines in general, then you might see it as a negative thing because single-dose vaccines aren't as effective as regular vaccines.
