PROVIDENCE, R.I. (WPRI) — The popular ride sharing service Uber is offering a unique way for Rhode Islanders to get vaccinated.

Kim Rizun, a nurse for Passport Health, “Ubered” all over the Providence area Tuesday to administer free flu shots to anyone who requested one through the Uber app. Rizun was prepared to administer 40 vaccines.

“If I can come to you and give you your flu shot, you can’t say well ‘I’m too busy or I can’t get to the doctor’,” Rizun said.

It turns out many people appreciated the convenience and posts from 15 different cities popped up on Twitter using the hashtag #UberForHealth.

In fact, the mayor of Syracuse, New York tweeted a photo of herself getting her flu shot Tuesday afternoon.

Thanks #UberForHealth for the flu shot today. An important reminder why we need to support ride sharing laws in #NYS. @Uber pic.twitter.com/TRAxYsXr88— Stephanie Miner (@MayorMinerSYR) October 25, 2016

Some of the other cities involved in this flu campaign were Boston, Chicago and Hartford.
