I think this study is very welcomed. It is a good one. I prefer this kind of studies/research to the ones about trivial opinions or fashion. Vaccines play an important role in our society. For sure, we have saved many lives thanks to vaccines. Nevertheless, we should not take this for granted. We should not abuse. We always tend to abuse. The same thing happens with the use of antibiotics. When we use them to much, well they become useless. Vaccines have the same problems. We use them too much, they stop helping and become dangerous. I am advocating for a better use of vaccines and traditional medicine.
