When you recover from a Virus, What stops you from catching it again?
Let's take a look on How this Immune Process Works in our Body.
The Immune Response
💪 When your body detect an Antigen (infectious agent), it releases Anti-Bodies.
💪 These bind to the antigen, neutralizing it or making it to be destroyed by immune cells.
💪 Our immune system's memory cell "remembers" previous antigens.
💪 If we're infected again, the cells rapidly generate antibodies to get rid of the antigens. This is what we refer to as Immunity.
Testing for Immunity
Anti-Body Type ⇒ IgM | IgG
When Production Start after Infection ⇒ 5-10 Days 10-14 Days
💪 Different antibodies have different production start times and duration in our Blood. We can test for them to tell if someone has had an infection.
Vaccines and Immunity
💪 Vaccines commonly use inactivated viruses or antigen fragments to imitate infection without causing disease.
💪 The Vaccine triggers an immune response so that our immune system's memory cells recognize the virus or other antigen if we're ever infected.
💪 For some diseases, vaccine-induced immunity lasts a lifetime. For others, it fades over time.
💪 For example, Flu Virus mutate, meaning that existing antibodies don't recognize them an yearly vaccination is needed.
As long as your immune system is running smoothly, you don’t notice that it’s there. But if it stops working properly – because it’s weak or can't fight particularly aggressive germs – you get ill.
Stay Safe, Stay Healthy.
