You can have several different ones, depending on what you think the outcome will be!

- if you think shots are more effective:

Participants who are given the flu vaccine will have less flu cases than the participants who are given the nasal spray.

-if you think the nasal spray is more effective:

Participants who are given the nasal spray will have less flu cases than the participants who are given the nasal spray.

if you think both are equally effective:

you actually can't do this one- as you don't have a "control" meaning participants who received neither the nasal spray nor the shot, for all we know, vaccinated people also didn't catch the flu!

If you think both are equally ineffective:

Participants who were given the flu vaccine and the participants who were given the nasal spray will still catch the flu.
