Got this from one of my FBF (Facebook Friends) and its too important to me not share with you guys as well.
I also highly recommend beyond all of start doing you own learning and researching on it as well. I mean this also applies beyond vaccination, immunization, circumcision, inactivism, breastfeeding, lactivism. To me I found its very important so you can be proactive in it. Also, please take everything with a grain of sat as well. Especially, pseudoscience part of it as well. This also applies to beyond as well.
