Aztra Zeneca Made Covid-vaccine BEFORE Pandemic AND Before 'Covid' Even Had a Name

The world was told of a pandemic in late 2019. The name 'Covid-19' came around in 2020.

There is a video on this channel from David Martin who has outlined the ORIGINS of the so-called 'virus', and it goes back MANY years before this pandemic was marketed to the world.

ALL Big Pharma companies KNEW before-hand that this was coming, so they were able to make vaccines in advance.

There is a BIG question I have however: The media claimed that vaccines have an 'expiration date' and I think it was only about 5-6 months at most, but don't quote me on this. IF the injection-serum was produced in 2018 or earlier, would it not have been spoiled? (I don't know....I'm just asking) It seems like an 'oddity' to me, though.
