Working of covid-19 vaccine:

Covid-19vaccine: This is an mRNA vaccine which is completely new one, that to not been widely used before.
Like other vaccines, this vaccine will be injected into the upper muscle of your arms.
when this vaccine is injected into our body, the mRNA present in it has a small coding or part of that virus, which then enters the cytoplasm of the cell where ribosomes read the coding present on it and form the protein.

But what is the role of this protein? The antibody get stimulates they think, this protein is a foreign particle he should be killed.
These antibodies form an army against these foreign particles and neutralize/kill them.
As we known mRNA has a coding of Covid virus. Hence antibodies kill the Covid virus also.
For future prevention, this antibody type is stored in our B cells.

Why this technique not be used earlier?

This type of mRNA vaccine is more unstable as compared to others.
This vaccine is stored at -70°C. and at normal refrigerated temperature -40°C, it can only last for five days.

Can the Covid-19 vaccine cause corona?

The answer is big No, Covid-19 vaccine does not contain the SARS-CoV-2 virus so it is not possible that you can contract covid – through the vaccine.

Can anyone take two different doses of covid vaccine,I mean 1st dose covishield and 2nd dose covaxin ?

No, we can’t take different doses of different vaccine. As covishield and covaxin are totally different vaccine from each other one contents the live cells and other the dead one. Research is on the way for mixing of different vaccine , but for now you can’t change your vaccine doses.
