The world is waiting for a game changing vaccine one
that's effective and just as importantly safe vaccine
makers are working to create a shop that offers
protection against cove in nineteen. Without making the
person getting the vaccine sick. So how does a vaccine
work. Hundreds of years of experience Telus vaccines
can Wear. Today vaccines are powerful tool to prevent
people from getting many infectious diseases like
tetanus measles and the seasonal flu. For many a
natural covad infection beats a mild illness and a quick
recovery. But unfortunately for some the virus moves
too fast and it's too strong for our immune system to
handle gracefully and maybe I didn't death. Sadly
hundreds of thousands of Americans have died as a
result of coping nineteenth. Solar vaccine is a way to
prevent people from getting sick and does so by giving
our immune system a competitive edge tickets are we
need. When your body is infected with a virus it's a
kind of wore a back and forth battle between the virus
and or immune system you musicianship but different
combat battalions there working together to kill the
virus before the virus schemes too much territory as
our body. He the first immune system it's kind. She's
troops act fast before knowing what the enemy even
looks like. Doing things like counting the fever to make
that infectious invaders comfortably on inside your
body. But what if the virus reaches that first line of the
defendants. Luckily the Indian army came quickly
deploy a second battalion called the adaptive immune
system soldiers they can adapt and learn what the
virus looks like to begin a more strategic operation
against the virus. This Italian the soldiers are called B
cells and T cells they announced a custom made fight
against the specific invader. Case cope in nineteen.
This playbook he sells get worse stuff that has invaded
the body and head out on the mission. You virus they
don't recognize they need to quickly figure out how to
make the right weapon to defeat the record. Golden
antibodies would keep hearings. Antibodies that
Blackstone and neutralize the virus. Another soldier
in that second battalion is that he sells one type of T
cell reinforces. Helping those he says sneaky
antibodies. Look here there's this special group of T
cells called killer T cells. They could these like highly
trained Navy SEALs go in for direct kill themselves and
the virus. An amazing coordination these sales and he
sales work together to Cuban leaders at the same time
and after successfully destroying the virus immune
system has one last special trick up its sleeve. Keeping
a kind of photographic memory and everything it sees
stored in a time capsule of them are. Called memory
cells and that's salute strategy usually means once our
immune system meets something it doesn't like it often
doesn't forget at least in the short term. And that's no
vaccine makes its way into the if you army playbook
the strategy is that when you get a vaccine it triggers
all the troops into action but without making you sick
and this last. Time capsule that means a vaccine you
get. Future but remember vaccines don't
actually keep you the virus and of the vaccines being
studied for Covert US have virus that's alive. Vaccine is
teaching your immune system fight the virus that we
can't get Kobe from getting a vaccine. There are
hundreds of vaccines in different phases of
development and we're waiting for the winning
candidates to prove to work can be safe. And given
the green light for distribution by regulators. News is
keeping track of the vaccine race you can stay updated

available for us all we can all do our part by wearing
