(Lively music playing)

Two brains move through a maze, chomping as they go. The brains merge into one large brain.

A banner over the brain reads: Hungry Brain!

A voice says, HUNGRY BRAIN!

An animation shows round creatures in horned helmets jumping up and down outside a long brown wall that resembles the Great Wall of China.

A narrator says, ATTACK! BUT, WAIT, ONE VALIANT HERO WILL PROTECT US FROM THESE HEINOUS INVADERS. ARE YOU READY TO FIND OUT HOW? HERE'S THE TOP ON THE IMMUNE SYSTEM.

Text reads: Top On The Immune System

(Bell ringing)

Text reads: #4. A Real Team Effort!

The narrator says, NUMBER 4: A REAL TEAM EFFORT. UGH! FLU ATTACK. RELAX, YOUR BODY'S GOT THIS. BUT FIRST WHITE BLOOD CELLS MUST REACH THE VIRUS TO FIGHT IT.

A white blob-shaped creature runs wearing red sneakers and a red headband.

The narrator continues, WHEN THE FLU'S BEEN FOUND, YOUR CELLS HIT THE HISTAMINE SIGNAL DILATING THE VESSELS IN THE INFECTED TISSUES AND TRIGGERING INFLAMMATION. THAT'S WHY YOUR NOSE IS BLOCKED. THE VESSELS BECOME PERMEABLE SO WHITE BLOOD CELLS CAN HIT THE SCENE. RESULT? LIQUID FLOWS FROM A RUNNY NOSE.

An illustration shows a nose dripping.

The narrator says, THESE SYMPTOMS ARE A SIGN THAT YOUR IMMUNE SYSTEM IS KICKING VIRUS BUTT.

Text reads: #3. The Job of Vaccines

The narrator says, NUMBER 3: THE JOB OF VACCINES. OUR IMMUNE SYSTEM IS PROGRAMED TO PROTECT US FROM BIRTH. MUCH OF OUR SYSTEM IS ALREADY ACQUIRED WHICH MEANS THAT WITH EXPERIENCE IT LEARNS TO SNIFF OUT THE BAD GUYS AND DEAL WITH THEM.

The blob of white blood cells wears a fedora hat and holds a magnifying glass.

The narrator continues, THAT'S WHERE VACCINES COME IN. A VACCINE IS AN INJECTION OF A DEAD OR VERY MILD VERSION OF A VIRUS. OUR BODIES RESPOND WITH ANTIBODIES: SUPER SLEUTHS AND VIRUS THRASHERS PAR EXCELLENCE. ANTIBODIES ARE STORED LIKE A MEMORY IN THE BODY AND ARE READY TO SMACK DOWN VIRUSES BEFORE THEY GET NASTY. THANKS TO VACCINES, SMALLPOX HAS BEEN COMPLETELY WIPED OUT. IT'S ESTIMATED TO HAVE SAVED NEARLY 5 MILLION LIVES A YEAR.

Text reads: #2. Be Careful!

The narrator says, NUMBER 2: BE CAREFUL! ONE IN 100,000 PEOPLE IS BORN WITH A DEFICIENT IMMUNE SYSTEM. OFTEN THESE PEOPLE CAN'T GET VACCINATED SO THEIR PROTECTION DEPENDS ON THE HEALTHY PEOPLE AROUND THEM MAKING SURE THEY'RE VACCINATED AGAINST DANGEROUS DISEASES. TOO RIGHT!

(Bell ringing)

Text reads: #1. It’s All About Dosage.

A blue creature wearing an apron pushes a dolly filled with cleaning products.

The narrator says, NUMBER 1: IT'S ALL ABOUT DOSAGE. VISITING AUNTY VERA IN HOSPITAL? WELL, MAKE SURE TO WASH YOUR HANDS. BUT GO EASY ON THE ANTIBACTERIAL PRODUCTS, THOUGH. THE IMMUNE SYSTEM NEEDS MICRO-ORGANISMS TO GET STRONGER, ESPECIALLY IF THEY'RE A YOUNG CHILD. IF WE WASH TOO MUCH, WE KILL THE GOOD BACTERIA ON OUR SKIN WHICH IS JUST WHAT THE BAD BACTERIA LIKES TO HAPPEN. YOUR IMMUNE SYSTEM IS YOUR GREAT WALL OF CHINA AGAINST BADDIES. TAKE CARE OF IT AND YOU'LL TAKE CARE OF THE VIRUSES TOO.

The white blood cell stands on the wall and blasts away the invaders below.
