From the researchers study on the subject, it looks like this is not going to be that difficult to break neither. The Chinese vaccination uses dead cells of the virus to make your body understand it, study it, beat it (well its already dead but you got it) and be ready for the virus, it is not the ideal situation but definitely 100% better than not having the vaccination, the UK one seems like it works in a way to make your body change, think of it like you are mutating yourself against the mutation of the virus. Not mutating in a way that you are going to be enlisted by charles xavier tomorrow, not that kind of mutation don't worry
but your body will change towards a human that is ready to fight these type of viruses, be more ready for anything.
If that is the case (I am not scientist, I am just telling what I have read) covid could mutate a million times and as long as it is about the same virus without too much change, we can defend ourselves.
