The vaccine MAY hopefully be effective... but again, what about those who think they MAY have the vaccine (an free ticket) and actually just got the placebo... the whole placebo thing is the pervert ingredient... they want to see how vaccine does compared to the ones who act similarly but do not have a chance... in other words D I E and contaminate a bunch of others before.
What I am trying to say, is that unless they receive the vaccine/placebos unbeknownst to them (they wouldn't know they are part of that test), their attitude and behavior will change. In other words their risk taking predisposition may become higher... which will make those who have the placebo more likely to contract the virus then those who are not participating in the "study".
One question I have also not yet found a clear answer to is, assuming the vaccine works (for the individual with it)... dose it prevent passing the disease on to others?
... J-D.
For any scientific trial to be truly effective the application of a double blind test is the most accurate and unbiased method. The use of a placebo is a must.
I'm no scientist but if a vaccine were to cure the disease what is there to pass to others.
