One of the first people to receive the vaccine in the U.S. was an environmental services worker who cleans the emergency room at a Dallas hospital.
Teresa Mata explains why she got the vaccine.
Mata said, "I feel good. I want to take the risk because I am diabetic for 13 years. So I work in this hospital, I love my job, but I want to protect each person and I want to protect my family and I want to protect myself."
