Pfizer COVID Vaccine for Younger Children Hits Snag

SPEAKER: How does a COVID-19

mRNA vaccine work?

COVID vaccines are now


Some of the COVID-19 vaccines

are mRNA vaccines, but what does

this mean?

mRNA vaccines are

antithetic from traditional


mRNA vaccines don't exposure you

to immoderate existent microorganism instead,

they're made with messenger

Ribonucleic Acid oregon mRNA.

This is simply a benignant of molecule that

gives instructions to the cell

for however to marque antithetic kinds

of proteins.

mRNA molecules are

a earthy portion of our cells

and however our bodies work.

Researchers person been working

with mRNA vaccines

for galore years.

They are made much easily

and safely successful a lab

than a vaccine that uses

a virus.

Because of this they tin also

beryllium made faster.

The COVID-19 mRNA vaccines

person passed galore tests successful labs

and successful thousands of people,

and conscionable strict standards

from the FDA.

So however bash these vaccines work?

First, a COVID-19 mRNA vaccine

is injected into a muscle

successful your precocious arm.

Some musculus cells instrumentality the mRNA

instructions successful the vaccine

and marque a harmless piece

of a macromolecule called

a spike protein.

This macromolecule is found

connected the extracurricular of the SARS-CoV-2

microorganism that causes COVID-19.

The musculus cells past destroy

the instructions for however to make

the spike protein.

The mRNA ne'er goes

into the nucleus of your cells

wherever your DNA is stored.

The recently made spike macromolecule now

sits connected the surface

of the musculus cells.

Your immune strategy senses

the spike protein

arsenic a overseas menace to destroy,

it starts making antibodies

to combat anything

with that spike macromolecule connected it.

This volition assistance your body's

immune strategy recognize

and combat the existent microorganism if it

ever shows up.

It's similar recognizing someone

by the chapeau they wear.

Your assemblage is then

prepared to spot COVID-19

and combat it disconnected earlier it grows

successful your body's cells.

Fast facts to remember

astir COVID-19 mRNA vaccines.

They assistance get your body

acceptable to combat disconnected the COVID-19

microorganism earlier it makes you sick,

they don't use

immoderate live, dead, oregon anemic virus,

they can't springiness you COVID-19,

they don't impact your DNA.

Want to larn more,

spell to to find more

accusation astir mRNA vaccines.

You tin besides larn much about

however the vaccines were approved
