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
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
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
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 cdc.gov to find more
accusation astir mRNA vaccines.
You tin besides larn much about
however the vaccines were approved
