This can probably be seen as a little heartless... but my number one priority is my child, not the community as a whole. And that's what's always been forefront in my mind when I debate whether to get DS vaccinated or not. I already have a DSS affected by something that "may" be vaccine related, therefore my DS is at a higher risk. I also have two brother's with the same disorder to a much greater extent, a sister that developed major allergies after being vaccinated (timing "may" be coincidental), and I only ever had one whooping cough vaccine due to having a reaction to the vaccine. After all of that, I think about the risk to DS well before I think about any potential risks to the community.
