Question two: Please translate the following.
How do the COVID-19 vaccines work?
To understand how the COVID-19 vaccines work, it’s important to understand these three words: pathogen, antibody, and antigen.
A pathogen is a tiny organism that causes disease. The SARS-CoV-2 virus that causes COVID-19 disease is a pathogen.
The human immune system responds to pathogens by producing antibodies. Antibodies help our bodies recognize and kill pathogens.
The specific part of a pathogen that causes the human body to form antibodies is called an antigen. When the human body is exposed to an antigen for the first time, the immune system responds by producing antibodies that are specific to that antigen.
