I don't know what he meant by "let's be honest". Maybe just a bad choice of words. Kind of seems insignificant to me.
Regarding proof, there seems to me that there is no such thing as absolute truth, but the closest thing we have is the scientific method. And I agree, if you are more concerned with the possibility of getting what ever the vaccine is for than you are with possible side effects from the vaccine it is up to you to choose. That is not something that science can decide for you.
I don't know what you heard about the MMR vaccine controversy, but the paper that showed the connection to autism got retracted and declared fraudulent. But I don't really care about that.
I'm sorry you stopped watching, Paul, and maybe I should have mentioned that he talked about a lot of stuff. There is a part further in to the clip, I think, regarding herbal medicine or alternative medicine and that part is the one that I would like people to listen to and that was why I posted it in that section of the forum. I understand this is your forum and you do what you will, I don't mind.
What I think was the point of his talk, and the point that I wanted to share is that there is a way to distinguish what is scientific "fact" and what some people claim to be scientific "fact". As there will always be frauds and mistakes I would suggest to anyone, reading this and who is interested, to look up the terms "systematic review" and "meta-analysis". There is a lot of research like this on a wide variety of substances and herbs and treatments and I think that you will find that you can really see what is true and what is fiction. http://en.wikipedia.org/wiki/Meta-analysis http://en.wikipedia.org/wiki/Systematic_review
And really the book "Trick or Treatment? Alternative Medicine on Trial" is a goldmine. Regardless of what your stance on this subject is now, I think it would be counter productive to reject something before looking at it. I will certainley, at least, look at information from sources I would not concider trustworthy. If armed with a critical mind, what harm could it do?
Also, I completely agree that there are conventional medicines not suitable for consumtion! And there IS natural remedies that work! The thing is that there is a way to see which those are. Not everything used in China for 5000 years really does work. Most things don't. Some do.
