Question

why can't vaccination prevent viral diseases? ​

Answer 1

• WELL I THINK IT IS NOT SO ...
• IT ACTUALLY DEPEND OF WHIXH VACCINATION U HAVE USE ... VACCINATION ARE GIVEN SO THAT BODY WILL BE ALREADY PREPARED TO FIGHT THAT PARTICULAR DISEASE WHICH CAN BE EITHER CAUSED BY VIRUS OR BACTERIA
• IF WE GIVE ALL THE VACCINATION FOR EVERY DISEASE SO THE BODY WILL NOT PRODUCE IT OWN RBC AND ONLY BY A SIMPLE FLU OR FEVER THE MAN WILL DIE
• IT DONT WORK IN VIRAL ANXIETY BUT NOT MOST OF THE TIME LIKE ...IT WORK ON COW POX WHICH IS VIRAL
• ACCTUALLY IT CAN FIND THISE DISEASE WHOSE VACCINATION IS GIVEN NO MATTER EITHER IT IS A VIRAL BACTERIA OR A SINGLE COMMODATION ONE
