I know I am chiming in late. Can't believe I missed a post about vaccines. As the others have stated, when you take your babies in, make sure they get all vaccines in their limbs-NEVER the SCRUFF! That includes all vaccines, and IMHO anything injectable that causes inflammation. The inflammation is what has been linked to VAS, or otherwise known as ISS(injectable site sarcoma), since other things have been traced to these sarcomas other than vaccinations. While it is considered rare to even get VAS it is more rare that other things cause it, but why not play it safe.
