I do know the answer now, and was tempted to post it, but I'm quite tired of doing your homework for you. I can't believe I am the only person intelligent enough to use Google, so I am stuck with the belief that you people are being intentionally obtuse. It's an annoying habit, to say the least.
If I produce the answer, then all you will do is take it to an even more absurd level. You just proved it. Eventually I'll be forced to admit I can't find any studies about the effects of vaccines in the second or third generation, that it appears that nobody has studied the effects of vaccinating the grandmothers, and then you can all scream Ah Ha! There could be a link to vaccines! They have not been proven safe!
Remember, the original contention was that the vaccines created the disease in infants. When I showed that the symptoms happened equally as often in babies that were not vaccinated, some of who had not even been born, you moved the bar a little lower.
At what point do you think maybe you should assume some burden of proof?
