People ask me if it is a good idea to vaccinate their child. That is a decision that should be made by each parent. Their are pros and cons to the concept and to each vaccine. Every parent should be well informed on the issue and of each vaccination and the disease that it is meant to treat. But, they should also be informed as to some of the behind the scenes issues like this article. As adults we may consider getting a vaccination for something, and this could have a serious impact on our health. And, we may not want to take that risk. As for IC, it defintiely can impact the pain and the way your immune system is reacting.
