The ridesharing company is handing out free flu shots on Tuesday, Oct. 25. All you have to do is choose the “Health” option in the Uber app that day between 11:00 a.m. and 3:00 p.m. to request a vaccine. As Uber writes in a company blog post, a registered nurse will come to administer the shot, which also comes with flu-fighting care packages.

The company first offered this UberHEALTH option two years ago, administering flu shots in Boston, New York, and Washington, D.C. Uber did it again last year, offering vaccines in more than 35 cities—they cost $10, but up to 10 people could be vaccinated with each request. This year, they’re completely free, though Uber has reduced the number of vaccines to five per trip. If the care package is the same as last year, you’ll get a water bottle, tissues, hand sanitizer, totebag, and lollipop.

Uber notes that about 20% of the population is affected by the flu each year, and getting a vaccine reduces the risk of someone else being infected by 50%-60%.
