You might want to reconsider your statement "nobody's forcing this vaccine...", because I've read several places where the makers of this vaccine are trying to get it mandanted for ALL children attending public school. There are many organizations actively lobbying against it.
Also, ALL vaccines carry huge health risks, and even if they're proven to be effective against what they're for (which has NEVER been done for ANY vaccine ever administered...please read here for overwhelming evidence of that: http://www.whale.to/vaccines.html ),one still has to weigh the alleged benefit of the vaccine against the KNOWN health risk of taking it.
