Pfizer Says Vaccine Booster Should Protect Against Omicron

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 signify?

mRNA vaccines are

various from standard


mRNA vaccines never expose you

to any genuine virus alternatively,

they are built with messenger

Ribonucleic Acid or mRNA.

This is a kind of molecule that

presents recommendations to the mobile

for how to make various types

of proteins.

mRNA molecules are

a normal aspect of our cells

and how our bodies work.

Scientists have been working

with mRNA vaccines

for lots of many years.

They are built more simply

and securely in a lab

than a vaccine that uses

a virus.

Simply because of this they can also

be built more rapidly.

The COVID-19 mRNA vaccines

have passed lots of assessments in labs

and in countless numbers of people today,

and meet rigid benchmarks

from the Food and drug administration.

So how do these vaccines work?

To start with, a COVID-19 mRNA vaccine

is injected into a muscle mass

in your higher arm.

Some muscle mass cells get the mRNA

recommendations in the vaccine

and make a harmless piece

of a protein identified as

a spike protein.

This protein is identified

on the outdoors of the SARS-CoV-two

virus that brings about COVID-19.

The muscle mass cells then damage

the recommendations for how to make

the spike protein.

The mRNA never ever goes

into the nucleus of your cells

wherever your DNA is saved.

The recently built spike protein now

sits on the surface area

of the muscle mass cells.

Your immune procedure senses

the spike protein

as a overseas danger to damage,

it starts producing antibodies

to combat everything

with that spike protein on it.

This will enable your body’s

immune procedure acknowledge

and combat the genuine virus if it

ever reveals up.

It can be like recognizing someone

by the hat they wear.

Your body is then

ready to spot COVID-19

and combat it off right before it grows

in your body’s cells.

Fast details to remember

about COVID-19 mRNA vaccines.

They enable get your body

ready to combat off the COVID-19

virus right before it helps make you unwell,

they never use

any are living, lifeless, or weak virus,

they can not give you COVID-19,

they never impact your DNA.
