What are the positive outcomes of vaccines?

Answer 1

the person who takes the vaccine wont die of polio (it causes weak muscles, affects the spinal cord,and might paralyze you), measles (causes a rash, runny nose ,fever, and it mostly lasts for 2 weeks) or tuberculosis (otherwise said as TB, it attacks the lungs and may cause death).

also when a virus attacks and there is a vaccine already injected into the human arm, the white blood cells are ready to fight and when the cells defeat the virus, the immune system grows stronger!

EXTRA FACTS ABOUT YOUR SELF AS VIRUSES

when you have cold (for example) that means you cant have that cold again (millions of different types of colds, so you get colds more then once)and as soon as that sickness is gone from your immune system, your body forms antibody's to defend yourself from the sickness you already got!

how our body defends us from sickness and viruses is that every time your white blood cells fight a sickness, the white blood cells become stronger, and the mucous in your nose or the hairs in your nose catches or traps the sickness until you sneeze it out into the air (the viruses are very small and travel throughout the air) and the saliva in your mouth helps trap the virus and makes it decay.

i hope this information helped you a lot :D have a nice day
