COVID flu vaccine: what you need to know


[MUSIC PLAYING]

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.

Do you want to learn more,

go to cdc.gov to find more

information on mRNA vaccines.

You can also learn more about

how the vaccines were approved

by fda.gov.
