<human>: 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?
<bot>: It depends on your perspective, but in general it’s considered to be a positive development for several reasons. First, it reduces the number of needles that people need to get vaccinated, which is safer and more convenient. Second, it makes it easier to track who has received the vaccination since everyone receives the same dose. Third, it increases compliance with vaccination programs because there are fewer barriers to getting vaccinated.
