One question someone may be able to answer me - if you do not have a sample of the virus or whatever causes the illness you are vaccinating against so that you can try and get the trial participant to "catch" it after being jabbed nor do you have a diagnostic test for that illness so cannot say 100% they caught it how can you claim this is a valid trial?
