<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 I think it’s generally a good thing. The single-dose flu shot is designed to protect you from the flu by giving you antibodies that help fight off the virus if you get sick. This is different than regular vaccines which are designed to teach your body how to make its own antibodies against the flu.
