Pfizer COVID Vaccine for Younger Children Hits Snag

SPEAKER: How does a COVID-19

mRNA vaccine work?

COVID vaccines are actually

accessible.

Some of the COVID-19 vaccines

are mRNA vaccines, however what does

this imply?

mRNA vaccines are

totally different from conventional

vaccines.

mRNA vaccines do not expose you

to any actual virus as an alternative,

they’re made with messenger

Ribonucleic Acid or mRNA.

This is a kind of molecule that

offers directions to the cell

for how you can make totally different sorts

of proteins.

mRNA molecules are

a pure a part of our cells

and the way our our bodies work.

Researchers have been working

with mRNA vaccines

for a few years.

They are made extra simply

and safely in a lab

than a vaccine that makes use of

a virus.

Because of this they’ll additionally

be made sooner.

The COVID-19 mRNA vaccines

have handed many assessments in labs

and in hundreds of individuals,

and meet strict requirements

from the FDA.

So how do these vaccines work?

First, a COVID-19 mRNA vaccine

is injected right into a muscle

in your higher arm.

Some muscle cells take the mRNA

directions within the vaccine

and make a innocent piece

of a protein known as

a spike protein.

This protein is discovered

on the surface of the SARS-CoV-2

virus that causes COVID-19.

The muscle cells then destroy

the directions for how you can make

the spike protein.

The mRNA by no means goes

into the nucleus of your cells

the place your DNA is saved.

The newly made spike protein now

sits on the floor

of the muscle cells.

Your immune system senses

the spike protein

as a international menace to destroy,

it begins making antibodies

to battle something

with that spike protein on it.

This will assist your physique’s

immune system acknowledge

and battle the actual virus if it

ever reveals up.

It’s like recognizing somebody

by the hat they put on.

Your physique is then

ready to identify COVID-19

and battle it off earlier than it grows

in your physique’s cells.

Fast details to recollect

about COVID-19 mRNA vaccines.

They assist get your physique

able to battle off the COVID-19

virus earlier than it makes you sick,

they do not use

any stay, useless, or weak virus,

they can not offer you COVID-19,

they do not have an effect on your DNA.

Want to study extra,

go to cdc.gov to seek out extra

details about mRNA vaccines.

You may study extra about

how the vaccines have been permitted

at fda.gov.
