How are microbes used in medicines?

Microbes are tiny organisms that cannot be seen by the human eye.
you get microbes that are good for you and microbes that are bad for you. everyone has an immune system, which is something that defends your body from bad microbes. the immune system is not an organ but its in your bloodstream and most of your organs.
in your immune system there are things called antibodies which kill bad microbes. when you have medicines and jabs, there are bad microbes inside the medicines/jabs. they always put in quite mild bad microbes though, so it doesnt make you ill but DOES prepare the antibodies so if they see the same kind of bad microbes again they will be able to kill them faster, giving you less chance of catching the desiese.
eg smallpox. in the smallpox jab they give you the smallpox that cows get (yes, cows can get smallpox too). but humans cant actually get ill from having small amounts of cow smallpox injected into them, because our antibodies can kill cow smallpox microbes easily. but when the antibodies kill the cow smallpox microbes, they remember them.so if you ever get human smallpox microbes inside you, the antibodies will remember how they killed the cow smallpox microbes and kill the smallpox microbes in the same way. because they have already killed the same thing before, they will kill them quiker, giving you MUCH less chance of the smallpox microbes getting through your immune system and giving you the deseise.


Answer:

As humans are eukaryotes, our genome is extremely difficult to truly decode due to processes such as exon shuffling, the genetic "junk" and likely dozens of other observed aspects of our genome.

Naturally, many people with genetic defects need a constant supply of medicines (diabetics will be used from here on out in this section). Creating insulin in a lab was very difficult before the onset of cDNA, which (long story made really really short) is placing the human insulin gene into yeast or another simple eukaryote. Thankfully, all eukaryotic cells "know" how to process our genome and human hormones can be made in vivo in laboratories in greater quantity than ever before

Correct, and as you see, even microbes are happy to help medicines do their work in a much better pace
