As we all know that in today's time the most hot topic in the world is corona virus or COVID vaccine . There are thousands of people who thinks about vaccine efficacy and its complications after the vaccinations , how it will work , how my body will react to the doses of vaccine to all the questions there is one answer that the corona vaccine is safe and can be taken without any worry . 

Now after taking the jab how it will work the question comes to our mind , the answer to this question is that our body will start making antibodies against the virus after some days of taking the first dose . The timing differs for different vaccines and it has been told by the scientists that the double dose is more effective than single jab of vaccine .

When we take vaccine our body starts reacting and give instructions to our cells to make a harmless protein that is unique to the virus . Now this will continue and cells will copy this harmless protein in bulk amount and these copies destroy the genetic material from the vaccine . Our bodies will now recognize that protein should not be their and body starts producing T-lymphocytes and B-lymphocytes which will help in remembering how to fight the virus .This explanation  is for mRNA type vaccine which contain COVID virus material.

Different vaccines works differently i will be posting other blocks for other vaccines as well .
