Phrases with «antigenic drift»

"Antigenic drift" refers to small changes or mutations that occur in the proteins on the surface of viruses. These changes happen over time, causing the virus to become slightly different from its original version. As a result, our immune system may not recognize the virus anymore, making it harder to fight off. This is why we need updated vaccines to protect against these new versions of the virus.
