. Even the OP's question may be considered an instance of the same class, all members of which take the form of an appeal to ignorance, and include an (often tacit) assumption which reduces to some version of: "we don't know everything it might be possible to know about vaccines and their effects, therefore vaccines should be regarded as unsafe
". My point is that we don't know everything about anything
, and never will, but this does not lead us to regard as generally unsafe most of the products we use (including those we consume), even when we are not familiar with every detail of their manufacture.
By their nature, vaccines are held to a higher standard than are many other types of product, and where safety is concerned, the burden of proof is high. Huge amounts of money and time are in fact dedicated to meeting this burden. What I think a thread like this one illustrates is that for some, it is a burden that can never
be met, because science will never be able to keep pace with imagination.
