How does immunology work?
How Does the Immune System Work? When the body senses foreign substances (called antigens), the immune system works to recognize the antigens and get rid of them. B lymphocytes are triggered to make antibodies (also called immunoglobulins). These proteins lock onto specific antigens.

- Passive Immunity.
- Innate Immunity.
- Adaptive Immunity.
How does the immune system fight a virus?
If an antigen enters the body and B-cells recognize it (either from having had the disease before or from being vaccinated against it), B-cells will produce antibodies. When antibodies attach to an antigen (think a lock–key configuration), it signals other parts of the immune system to attack and destroy the invaders.
Can a good immune system prevent Covid?
It’s important to know that a strong immune system will not prevent you from contracting COVID-19. SARS-CoV-2, the virus that causes COVID-19, is a novel pathogen, meaning those who contract it have no existing antibodies to mount a defense.
