See my post 1469....and I did ask you if that was what you meant.
If you were asking if all of the Covid vaccines are the same....well, then the answer to that is no they aren’t.
The Oxford vaccine is a recombinant vaccine....as far as I am aware most of the others are
Modified messenger RNA vaccines.(this is true of the Moderna vaccine which is looking like it will get authorisation in the US very soon)
I can’t tell you what the Russian Sputnik vaccine is as there is little information about it...likewise the Chinese vaccine.

I hope this is what you were looking for.
