The Western vaccines are going through effectively the same processes that a regular vaccine does. What's changed is that some stages are being run concurrently; in the case of the Oxford vaccine a lot of work on MERS was able to be repurposed saving a lot of development work; in the US they're using a completely new development "platform " for the first time in anger (it's gone through a lot of testing already)
A few tears ago this type of accelerated vaccine development simply wouldn't have been possible, but we're effectively at a tipping point for this type of medical research.
By the time any Western vaccines is made widly available, it will have been tested on 30,000 to 50,000 people already - and the core technologies will have been tested on millions of people over the last 5 years or so
The key thing that has been omitted though is the long term effects, obviously. Well have no idea what the effect of this vaccine is after twelve or eighteen months. I think that’s a particular worry for the American one as it’s a new technique.
True long term effects of any vaccine aren't discovered during the current process.
Realistically, there needs to be some perspective in where the risks actually lie and what they are. The real risk of a vaccine is that rather than immunise, it accelerates the effects of the virus - which is why one ifbthe early tests in animals is to overexpose them.
These are not drugs and cannot be compared to thalidomide. If they don't act as a catalyst to the virus, and don't cause an illness directly themselves, they're inactive bodies that tge immune system either learns from, or ignores.
The vastly more likely scenario is that rather than be dangerous, it simply doesn't work - which is what Phasee III trials determine
