SPEAKER: How COVID-19 works
does the mRNA vaccine work?
Vaccines against COVID are now available
available.
Some of the vaccines against COVID-19
are mRNA vaccines, but what does it do
This means?
mRNA vaccines are
different from traditional ones
vaccines.
mRNA vaccines do not expose you
instead of any real virus,
they were made with Messenger
Ribonucleic acid or mRNA.
This is the kind of molecule that
gives instructions to the station
how to make different types
protein.
mRNA molecules are
a natural part of our cells
and how our bodies work.
The researchers worked
with mRNA vaccines
for years.
They are easier to make
and safe in the lab
than the vaccine he uses
virus.
That’s why I can too
be faster.
mRNA vaccine against COVID-19
passed many tests in laboratories
and in thousands of people,
and meet strict standards
from the FDA.
So how do these vaccines work?
First, the mRNA vaccine against COVID-19
is injected into the muscle
in the upper arm.
Some muscle cells take up mRNA
instructions in the vaccine
and make a harmless piece
so-called protein
spiky protein.
This protein has been found
on the outside SARS-CoV-2
virus causing COVID-19.
Muscle cells then destroy
instructions on how to do
spike protein.
mRNA never goes
in the nucleus of your cells
where your DNA is stored.
Newly made spike protein now
sitting on the surface
muscle cells.
Your immune system feels it
spike protein
as a foreign threat of destruction,
begins to produce antibodies
fight against anything
with that spiky protein on it.
This will help your body
the immune system recognizes
and fight the real virus if it is
ever appear.
It’s like recognizing someone
by the hat they wear.
Your body is then
ready to spot COVID-19
and fight before it grows
in the cells of your body.
Quick facts to remember
on mRNA vaccines against COVID-19.
They help get your body
ready to fight COVID-19
virus before it makes you sick,
do not use
any live, dead or weak virus,
I can’t give you COVID-19,
do not affect your DNA.

go to cdc.gov to find out more
information on mRNA vaccines.
You can also learn more about
how vaccines are approved
at fda.gov.
