DTaP Vaccine – Vaccines and Your Baby – The Children’s Hospital of Philadelphia (6 of 14)


>>THANK YOU. THAT’S BETTER. THAT’S A LITTLE BETTER. THE NEXT VACCINE THAT WE’RE
GOING TO TALK ABOUT IS REALLY THREE VACCINES IN ONE. BECAUSE WE ARE ABLE TO EASILY
COMBINE THESE VACCINES, CHILDREN CAN GET ONE SHOT
INSTEAD OF THREE. THE VACCINE IS CALLED DTAP. LETS START WITH THE D. WHEN MY FATHER WAS A CHILD THIS
BACTERIAL INFECTION WAS ONE OF THE MOST COMMON
KILLERS OF TEENAGERS. DIPHTHERIA CAUSES A THICK
COATING AT THE BACK OF THE THROAT THAT MAKES IT
DIFFICULT FOR CHILDREN TO SWALLOW AND BREATH. WHILE IT’S GROWING IN THE THROAT
THE BACTERIA MAKES A HARMFUL PROTEIN, A POISON CALLED A TOXIN,
THAT ATTACKS THE HEART, AS WELL AS THE KIDNEY AND
ALSO THE NERVOUS SYSTEM. NOW BECAUSE OF THE DIPHTHERIA
VACCINE ONLY ABOUT 2-5 CHILDREN GET DIPHTHERIA
EVERY YEAR IN THE UNITED STATES. BUT THE DISEASE CONTINUES TO
OCCUR IN OTHER PARTS OF THE WORLD. BECAUSE INTERNATIONAL
TRAVEL IS COMMON, THE DIPHTHERIA VACCINE IS STILL
IMPORTANT FOR OUR CHILDREN. THE SECOND LETTER OF DTAP
VACCINE IS T FOR TETANUS. TETANUS IS THE ONLY VACCINE THAT
PREVENTS AN INFECTION THAT IS NOT TRANSMITTED FROM
ONE PERSON TO ANOTHER. TETANUS BACTERIA LIVE IN THE
SOIL AND ENTER THE BODY AFTER A CUT OR A PUNCTURE WOUND. TETANUS, LIKE DIPHTHERIA, IS A
BACTERIUM THAT MAKES A TOXIN, THE TETANUS TOXIN INVADES THE
MUSCLES AND CAUSES STRONG AND PAINFUL MUSCLE SPASMS. THE INFECTION IS ALSO KNOWN AS
“LOCK JAW” BECAUSE THE TOXIN CAN AFFECT THE MUSCLES OF THE JAW. EVERY YEAR SOME PEOPLE IN
THE UNITED STATES GET TETANUS AND DIE FROM THE DISEASE. BECAUSE THE TETANUS BACTERIA
WILL ALWAYS BE PRESENT IN THE SOIL, THE POSSIBILITY OF
INFECTION WILL NEVER BE ELIMINATED; SO IT’S IMPORTANT TO BE IMMUNIZED. THE LAST LETTER OF THE DTAP
VACCINE IS P FOR PERTUSSIS, AN INFECTION WITH A VERY
RECOGNIZABLE SOUND. [SOUND OF BABY COUGHING] PERTUSSIS AS A BACTERIUM THAT
CAUSES A THICK STICKY MUCUS THAT CLOGS THE WINDPIPE. CHILDREN INFECTED WITH PERTUSSIS
BACTERIA COUGH REPEATEDLY, OFTEN TURNING BLUE
BEFORE THEY BREATHE IN.>>THE COUGHING EPISODES,
I MEAN, SOMETIMES THEY LASTED, YOU KNOW,
FOR A MINUTE AND A HALF. AND THAT MINUTE AND A HALF IS
THE LONGEST MINUTE AND A HALF YOU CAN IMAGINE.>>WHEN THEY BREATHE IN AGAINST
THEIR NARROWED WINDPIPE, THEY MAKE A WHOOPING SOUND. THAT’S WHY THE DISEASE IS ALSO
KNOWN AS “WHOOPING COUGH.”>>THERE WAS ONE TIME,
PROBABLY FOR ABOUT TWO DAYS WHERE THEY WEREN’T SURE. THE INFECTIOUS DISEASE
SPECIALIST CAME IN AND HE SAID, “YOU KNOW, I’VE TREATED
A LOT OF PERTUSSIS CASES.” HE SAID, “THIS IS A SERIOUS ONE.” HE SAID, “I CAN’T GIVE YOU ANY
GUARANTEES.” AND THAT PROBABLY WAS THE
HARDEST THING FOR ME TO HEAR.>>ALTHOUGH SOME PARENTS MAY
THINK THAT WHOOPING COUGH IS A RARE DISEASE IN THE
UNITED STATES, IT ISN’T. EVERY YEAR MANY
ADULTS GET PERTUSSIS. IF YOU’VE EVER HAD A COUGH THAT
LASTED LONGER THAN FIVE DAYS, YOU MAY WELL HAVE HAD IT. AND IF YOU HAVE CHILDREN, THEY
CAN EASILY CATCH IT FROM YOU.>>AS WE WALK ALONG THE STREETS
NOW, I HEAR SOMEONE COUGHING, AND MY HUSBAND AND
I WILL LOOK AT EACH OTHER, “OH, THAT PERSON MAY HAVE
PERTUSSIS AND NOT KNOW IT.”>>ALTHOUGH THE THREE DISEASES
WE JUST TALKED ABOUT, DIPHTHERIA, TETANUS, AND
PERTUSSIS ARE ALL VERY DIFFERENT, THE BACTERIA THAT
CAUSE THESE DISEASES SHARE ONE THING IN COMMON. THEY ALL MAKE HARMFUL PROTEINS
CALLED TOXINS. TO BE PROTECTED AGAINST THESE
DISEASES, YOU NEED TO HAVE IMMUNITY TO THE TOXINS. SO HOW CAN YOU GET IMMUNITY TO THE
TOXINS WITHOUT BEING HURT BY THEM? TOXINS ARE FIRST PURIFIED AWAY
FROM THE BACTERIA AND THEN MADE HARMLESS BY A CHEMICAL. THESE HARMLESS TOXINS
ARE CALLED TOXOIDS. TOXOIDS GIVE CHILDREN IMMUNITY
TO THE TOXINS WITHOUT CAUSING THEM TO SUFFER THESE
TERRIBLE DISEASES.
