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.
