I'VE RECOVERED FROM COWPOXNOW I WILL NEVER CATCH SMALLPOX.
OHH IT'S SO NICE . BUT WE'RE STILL AT RISK.
BUTT WHYY SOO????
I'M GOING TO SCRATCH PUS OF COWPOX IN YOUR ARMS.
IWANT TO TAKE PUS FROM YOUR BLISTERS.
EARLIER ALL THE DAIRYMAIDS USED TO CATCH COWPOX FROM COWS IN THEIR FARM.
I RECOVERED FROM COWPOX.
ONCE EDWARD JENNER AT THE AGE OF 13 HEARD A MILKMAID SAYING "I SHALL NEVER HAVE SMALLPOX FOR I 'VE HAD COWPOX.
--I DIDN'T EVEN CATCH SMALLPOX --I KNEW IT BECAUSE YOU WERE ALREADY IMMUNISED BECAUSE OF COWPOX VIRUS.
SO AFTER BEING GROWN UP EDWARD TRIED AN EXPERIMBENT IN WHICH HE TOOK PUS FROM THE BLISTERS OF A COWPOX PATIENT. AND THEN, HE SCRATCHED THE PUS INTO THE ARMS OF AN EIGHT-YEAR-OLD BOY NAMED , JAMES PHIPS.
NOW I'VE DISCOVERED WHAT IMMUNISATION FOR A DISEASE IS AND HOW IT IS DONE.
THEN JAMES RECOVERED AFTER SOMEDAYS AS THE VIRUS WAS VERY MILD . THEN LATER EDWARD INFECTED JAMES WITH SMALLPOX.
NOW I AM INFECTING YOU FROM SMALLPOX.
JAMES DIDN'T EVEN CATCH THE INFECTION OF SMALLPOX AS HE WAS ALREADY INFECTED FROM COWPOX AND HIS IMMUNE SYSTEM HAD KILLED COWPOX VIRUS AND REMEMBERED IT. SO WHEN THE SMALLPOX VIRUS ENTERED HIS BODY HIS IMMUNE SYSTEM ATTACKED IT WITH EVEN MORE EFFECIENCY.
IN VACCINATION WE FOOL THE IMMUNE SYSTEM BY SENDING WEAK VIRUSES INTO THE BODY WHICH THEN GETS KILLED AND OUR IMMUNE SYSTEM REMEMBERS IT. AND WHEN THE REAL STRONG VIRUSES ENTERS THE BODY OUR IMMUNE SYSTEM ATTACKS THEM WITH EVEN MORE EFFECIENCY.
