Pfizer Says Vaccine Booster Ought to Shield In opposition to Omicron

SPEAKER: How does a COVID-19

mRNA vaccine work?

COVID vaccines are actually

accessible.

A number 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 can be a sort of molecule that

provides directions to the cell

for learn how to 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’re made extra simply

and safely in a lab

than a vaccine that makes use of

a virus.

Due to this they will 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 learn how to 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 overseas menace to destroy,

it begins making antibodies

to struggle something

with that spike protein on it.

It will assist your physique’s

immune system acknowledge

and struggle the true virus if it

ever reveals up.

It is like recognizing somebody

by the hat they put on.

Your physique is then

ready to identify COVID-19

and struggle it off earlier than it grows

in your physique’s cells.

Quick info to recollect

about COVID-19 mRNA vaccines.

They assist get your physique

able to struggle off the COVID-19

virus earlier than it makes you sick,

they do not use

any stay, useless, or weak virus,

they cannot offer you COVID-19,

they do not have an effect on your DNA.

Need to study extra,

go to cdc.gov to seek out extra

details about mRNA vaccines.

You can too study extra about

how the vaccines have been accredited

at fda.gov.
