A high school junior is the one of the first teens to be part of Pfizer's COVID-19 vaccine trial at Cincinnati Children's Hospital.
Officials say about 60 other children have also gotten the vaccine across the country as the race to find a treatment marches on.
Katelyn Evans said she hopes to help with finding a solution and to inspire others her age to do the same.
"I figured, like, it would be a good opportunity to help people out," Evans said.
It's a message of selflessness that Evans, 16, hopes will catch on with her peers.
In interviews provided by Cincinnati Children's Hospital, the teen said she first considered being part of the Pfizer COVID-19 vaccine trial in the spring.
She received a dose Wednesday, according to doctors.
They said she'll get another dose in 3 weeks and blood will be drawn to test her body's response.
"If any information that they can get from me can help, like, get a vaccine out sooner and help everyone out there, I feel like I can do it," Evans said.
Doctors at Children's Hospital are approved to enroll 16-year-old and 17-year-old participants as of now.
They want approval by an Institutional Review Board to enroll 12-year-old to 15-year-old participants by next week.
The teen's mother, Laurie Evans, said when she volunteered herself, her children wanted to as well.
She said the process has been comfortable.
"They told us things to expect, possibly, if there are any side effects or anything like that. Doesn't sound like there are very many though. My daughter will keep a diary, and then, they're going to give us a card with a number that we can call 24/7 with a nurse," Laurie Evans said.
Doctors said people like Katelyn Evans are critical as they learn more about treating COVID-19 by the day.
"They need all the numbers they can get, so I'm definitely going to ask my friends to do it as well," Katelyn Evans said.
In their interviews provided by Children's Hospital, the mother and daughter said they felt compelled to participate and help.
Doctors said they'll continue to enroll for 6 to 8 weeks and hope to have results by February 2021.
They also said Children's Hospital is expected to be one of five sites enrolling children as young as 12 years old if approved by the board.
