I think by now it is safe to assume that a Virus of some form
or another will be infecting the United States more and more frequently. COVID is just the current outbreak. I know
this sounds grim, but it is our new reality.
What can we do to protect ourselves and our families? Quite Simply: We must build an Iron-Clad Immune System. Our Immune System is magnificent, and when optimal it fights off infection and
disease. It has a number of ways to detect and destroy anything it recognizes
as foreign to your body, including bacteria, viruses,
fungi, parasites, or unhealthy cells.

How Does the Immune System Fight COVID-19?
One of the keys to combating COVID-19 is understanding how our
immune system responds to SARS-CoV-2, the virus that causes the disease. We can
potentially use this information for a number of purposes, like trying to
predict the likelihood of severe illness, preventing or treating serious
complications, developing a vaccine, and understanding if reinfection is
How does the body usually fight off viruses?
Let’s start with the basics of how your body responds to
and fights off a virus. Our body’s immune response is broken down into two
systems that work together in different ways to protect us: the innate and
adaptive (or acquired) immune systems.
Innate immune system
Your innate immune system is the first line of defense
against viruses, taking minutes to hours to kick in. It provides a general
defense against invaders. This system includes physical barriers like skin and
protective layers in our throat or gut, chemicals in our blood, and different
immune cells to fight infections.
The main purpose of this response is to stop the spread of
the virus throughout the body.
Adaptive immune system
While this is going on, your adaptive immune system starts
developing antibodies and white blood cells to both attack and remember the
virus, making it easier to fight it again. Compared to your innate immune
response, this response is more specific for the virus.
Your adaptive immune response is also slower, usually
taking days to weeks. This is why even though you might be infected with
SARS-CoV-2, it can take days to a few weeks for your blood to show
antibodies for the virus and for you to start getting better.
As part of this response, your body creates B cells, which
are white blood cells made by your bone marrow. These cells make antibodies
that turn on your immune system against the invader. These antibodies are
specific to the virus and will bind to it, tagging it to be destroyed by other
Some B cells work to fight the current infection, while
others are stored in the body as a memory of the virus to fight future
infections, sometimes lasting for decades.
This is generally how many vaccines work. They use your
adaptive immune system to create long-lasting memory cells. For example, memory
B cells you develop from getting the smallpox vaccine can last over 50
years. However, some vaccines may require multiple doses to get an adequate
immune response, and some require boosters as the initial protection starts to
T cells are also white blood cells that are part of your
adaptive immune system. Some T cells stimulate B cells to make antibodies,
while others kill cells that have been infected by the virus. On top of that,
these cells use molecules called cytokines to act as messengers to the rest of
the immune system. Cytokines are produced by some of the immune cells in our
innate immune response as well.
As a part of both the innate and adaptive immune responses,
cytokines can play a large role in the development of severe COVID-19. More on
How does the immune system respond to COVID-19?
Researchers have been trying to understand why some people get sick from COVID-19 while others do
not. Looking at how the immune system responds to the virus can give us some
idea, and it can possibly help us try to predict the course of the disease in
people who have been infected.
Under normal circumstances, the innate immune response
kicks in first to attack and clear out the virus, followed by the adaptive
immune response to remove any remaining virus and create a memory for future
infections. For people with asymptomatic or mild cases of COVID-19, everything
tends to work together as it should, or at least it does not progress to a severe
disease that requires hospitalization.
But in severe cases, especially with older people,
research has suggested that sometimes the different arms of the
immune response can be out of sync. This can create a perfect storm, leading to
some of the complications that we’ve seen in severe COVID-19 cases that become
