The emergency contraceptive is now available in vending machines at Shippensburg University.
School officials say the decision to sell the pill in vending machines was made to help students feel more comfortable.
"We had some conversations with them and they did a survey of the student body, and we got an 85 percent response rate that the students supported Plan B in the House Center," Dr. Roger Serr, VP of Student Affairs at Shippensburg University, told local station WHP.
The university does not profit from selling Plan B.
"We were uncomfortable providing it for free because that would mean we were supporting Plan B with either state money or fee money," Serr said.
The pill can be legally sold over-the-counter to anyone over the age of 17.
Plan B contains hormones that are meant to disrupt ovulation or prevent fertilization from happening.
