A few of you have disquiet about the short time that is taken to bring in these vaccine's.

Why has it been so quick when 6-7 years is the norm.

There was a specialist on the TV some weeks ago who gave a bit of an insight to this subject.

Do not take the following as gospel it just the jist as I remember it.

Medical research into various "BUGS" etc. is going on all the time.

Research labs all over the country are researching potential threats as well as relooking at existing ones to improve the drugs for them.

It appears in this case that it may have been related to the Ebola or Sars virus's or that the research that was/has been done on those could be of benefit for Covid-19.

Some bright spark/s said, instead of doing it in the old way, what if we try to due it this way ?
Sort of instead of trying to kill the virus itself (the old way)lets wrap it in a preventative coating that gets to our good bits first and protects them. This has been shown in presentations on TV which explain far better than I.

So you could say they did not try to reinvent the wheel but just wrapped it up.

You all know that advanced medical research is carried out to have defenses against Chemical Attacks in whatever form it may come.

Yes there will be some problems with people rejecting the vaccine but that's always been the case.

The other thing about the short time is that they had ample people to test on.

In most cases you have a very small number of people to be able to test, as their condition is not very common. Say instead of 20,000 they have 20 to test and the results take time to see if they work.

As I said this is the jist of what I remember.
