Some people believe that research of medicines should be directly based on human trial. Is this the right way give your opinion and discuss its advantages and disadvantages.

In recent years, medicines are researched by using

animals

such

as rats ,rabbits or cows as a trial.

However

, many people support that medical research should be tested by

humans

directly

instead

.In my point of view, I barely agree with

this

statement due to several reasons. On one hand,

Humans

are surely mammals but it does not mean that

humans

and

animals

are always having the same body, organs and reactions.

Hence

, the medicines may give an

effect

on

animals

differently from the individuals. Actually, People seems to have more complex body than

animals

.

For example

, If we injected

medicine

into a rat, the hair of the rat may be growing while

humans

may not have an

effect

like

this

.

Therefore

, if you test with

humans

,

then

you will recognize the true results as what will actually happen.

On the other hand

, human safety is a significant thing to be concerned about.The

medicine

that did not approve yet may not safe enough for people.

For example

, covid vaccination , a kind of

medicine

, has

also

been tested on mammals

first

before giving to

humans

since scientists must recheck

first

. The drawback of

this

is that it may cause a bad

effect

on death if the quality of the

medicine

is worst. In conclusion, it has both pros and cons to testing pills on

humans

. I barely agree with

this

statement reason that you will get the real results ,

on the other hand

, it may give a bad

effect

if the

medicine

quality is terrible.
