Autism and Vaccinations

     This is what I would research.  I want clear answers and I know that many other people on this earth do as well.  I remember for a while reading research that linked autism with vaccinations.  Then, this was shown to be incorrect and now the stance is that there is no link between the two.  However, I constantly read statistics that make me feel that maybe there really is a link.  I think that there are a lot of people in pain.  They had a child who seemed to be developing normally and then, just out of the blue, they felt as if that child was taken from them.  They want answers and they deserve answers.  I have very educated friends, who are aware that research is now telling us that autism is not caused by vaccinations.  However, they will all swear that their child was perfectly normal, they took them to get their shots, and the next day that child was autistic.  I don't know the answers, but I would sure like to.  If I could research anything, it would be to find out 100% for sure if autism is linked to vaccines.  If not, my next research would be to find out what is the cause then, if not the vaccines.  I have parents that I work with that are too scared to get their children vaccinated.  I know that I am supposed to explain to them how beneficial these vaccines are and how their is no link between them and autism.  However, what if I am wrong?  Could all of the people that swear their child became autistic immediately after vaccinations be wrong?  I am not confident that there is not a link.  I want to be confident and sure and I am neither of these things.

Reasearch Question????????????

     Hello, friends!  I am having a bit of a struggle trying to decide on a good, manageable research question.  I am very interested in learning about whether center based options or home visiting options are more successful for families and children.  I have read that center based options are more effective.  However, in my program we have both and I see that the home visitors work more in depth with the family and seem to have a better impact on helping the family to improve their life situations, which would seem to be more life long and also to have a greater impact on the success of the child and the family.  So, my question would be which one is right?  Does being in a center have a greater impact on future success for that child, or home visiting?
     What really worries me is that this is too large of a topic.  I am worried that it is too broad or too general and that I will have a difficult time with it.  However, our instructor seems to think that this is a workable question.  What do you guys think?  Is it manageable?  Is there a way to focus it down a bit more?
