As we know that corona virus was born in a virus studying university in china and now the whole world is suffering from it.
And now I will tell you that how actually corona virus attacks us
This virus enters our mouth , nose and eyes and then through these parts it goes to our lungs where the real game starts so now after entering our lungs corona virus choses a single cell and then . as we know that cell has a outer covering so the corona virus put its keys in the keys of the cell and take control over it and enters the cell and then once the cell is hijacked by the virus then the virus starts making its multiple copies in the cell and after a week or 2 weeks the cell is full of virus its capacity is full and now the cell blasts and corona virus spreads in whole lungs and tries to capture more cells to make more copies.
and now comes the turn of our immunity system so when corona virus makes its copies and the cell get blasted the immunity system comes and releases some key antioxidants which then locks on corona virus corona virus keys and then the work is of WBC ( white blood cells )so then our immunity system tells our WBC that they have to swallow all antioxidants and as we know that antioxidants are locked with the virus so when WBC swallows antioxidants the virus also get been swallowed by WBC and the virus dies.so now you have all been thinking that if our immunity system can beat virus then why people die .so the answer is when the virus attacks our body the immunity system needs to research the DNA of virus and it also needs to make special antioxidants and as you have heard that the most danger of this virus is for old people because the immunity system of old people is weak and that's why it take time to make antioxidants and they are made less because of weak immunity system and now I will tell you about work of a vaccine so the work is when our immunity system is researching about virus so the vaccine goes to immunity system and in advance gives the information of the virus for which the immunity system was researching and now immunity system knows that what type of virus is this and now it starts preparation in advance and beats the virus.
