Pfizer Says Vaccine Booster Ought to Shield Towards Omicron

SPEAKER: How does a COVID-19

mRNA vaccine work?

COVID vaccines at the moment are

out there.

A few of the COVID-19 vaccines

are mRNA vaccines, however what does

this imply?

mRNA vaccines are

completely different from conventional

vaccines.

mRNA vaccines do not expose you

to any actual virus as a substitute,

they’re made with messenger

Ribonucleic Acid or mRNA.

It is a sort of molecule that

offers directions to the cell

for how one can make completely 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’ll additionally

be made quicker.

The COVID-19 mRNA vaccines

have handed many exams in labs

and in 1000’s 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 one 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 risk 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 actual virus if it

ever exhibits 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 information 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, lifeless, or weak virus,

they can not provide you with COVID-19,

they do not have an effect on your DNA.

Wish to be taught extra,

go to cdc.gov to seek out extra

details about mRNA vaccines.

You may as well be taught extra about

how the vaccines had been authorized

at fda.gov.
