Be sure to get a good night's sleep before you get your flu shot...

If you've made an appointment to get your flu shot be sure to catch up on your sleep first...

Researchers at the University of Chicago say that the flu shot will be up to 50% More effective if you're not sleep deprived. 

Taking a nap before or after your shot won't help much. You really need to be well rested for several nights prior to your vaccination for optimal protection.
