Health Matters: How Vaccinations Work

By WVUA 23 Digital Reporter Kyrsten Eller

There has been lots of talk about vaccines recently with the ongoing spread of the COVID-19 virus. Vaccines are used to protect people against deadly viruses, but people often don’t tend to realize how they work.

According to the University of Alabama College of Community Health Sciences Professor Dr. Pamela Payne-Foster, vaccines work by entering an antigen into the body.

“The antigen is the bacteria of the virus, and since the body has an immune system that makes antibodies, antibodies are the other immune cells that fight against it,” said Dr. Payne-Foster. “When they see it again, they will fight against it.”
