SPEAKER: How does a COVID-19
does mRNA vaccine work?
COVID vaccines are now
available.
Some of the vaccines against COVID-19
are mRNA vaccines, but what do
does it mean?
mRNA Vaccines is
different from traditional
vaccines.
mRNA vaccines do not expose you
to an actual virus instead,
they are made with messenger
Ribonucleic acid or mRNA.
It is a type of molecule that
give instructions to the cell
for how to make different types
of proteins.
mRNA molecules is
a natural part of our cells
and how our bodies work.
Researchers worked
with mRNA vaccines
for many years.
They are made easier
and safe in a laboratory
as a vaccine that uses
a virus.
As a result, they may also
made faster.
The COVID-19 mRNA vaccines
passed many tests in laboratories
and in thousands of people,
and meet strict standards
of the FDA.
So how do these vaccines work?
First, a COVID-19 mRNA vaccine
is injected into a muscle
in your upper arm.
Some muscle cells take up the mRNA
instructions in the vaccine
and make a harmless piece
of a protein called
an acre of protein.
This protein is found
on the outside of the SARS-CoV-2
virus that causes COVID-19.
The muscle cells then destroy
the instructions for how to make
the spike protein.
The mRNA never goes
in the nucleus
where your DNA is stored.
The newly made vein protein now
sit on the surface
of the muscle cells.
Feel your immune system
the spike protein
as a foreign threat to destruction,
it starts making antibodies
to fight anything
with the spike protein on it.
It will help your body
recognize immune system
and fight the real virus if that is the case
ever appears.
It’s like recognizing someone
by the hat they wear.
Your body is then
willing to detect COVID-19
and fight it before it grows
in the cells of your body.
Quick facts to remember
about COVID-19 mRNA vaccines.
They help to get your body
ready to fight the COVID-19
virus before it makes you sick,
they do not use
any live, dead or weak virus,
they can not give you COVID-19,
it does not affect your DNA.

information on mRNA vaccines.
You can also learn more about
how the vaccines were approved
by fda.gov.
