I think the idea with vaccines is that you have to weigh the good against the bad. My situation with yeast is not bad enough that I would consider a vaccine, but if it were life threatening, I would. There are always going to be a certain group of people that react poorly to vaccines. They may be allergic to something in the suspension that carries the vaccine, there could be an abnormal immune response. I think vaccines are very important in some cases, in others, perhaps not so much. It is important I think to view each indivdual situation instead of saying, “Vaccines don’t ever do this” because sometimes they will have adverse effects. However, it is important to remember that even natural products can cause very severe, even life-threatening reactions in a subset of people. The key here is, everybody is different. We are not one homogenous population where a vaccine is always going to work and always be safe. It is just not possible.
