Vaccines

What is the danger of getting the same vaccine twice? My six year old has received all of her vaccines on time. Her last set she got was about two years ago. The doctors office, believe it or not, cannot find the record. Now she is in first grade, we are changing school. They are saying she must get the same shots over again and an additional one. I do not want to do this, but I'd also like to know the danger of what they are suggesting is.

There shouldn't be any problem getting re-vaccinated with any typical vaccine she needs. A tetanus vaccination shouldn't be given without a 2-3 year space inbetween but most others can be given again without any problem.
