OP: It's all personal choice on how a person wants to keep a strong immune system, naturally or with drugs, I prefer the first but that's me. I don't like for starters the preservatives in the vaccines, and most contain aluminum, so saying this may sway you, don't know. Many many don't think as I do, but that's OK. Overall I don't see an issue with a vaccine after a concussion...but the expert may come along and confirm this..

Give me good ole Vit C, Vit D, Zinc and of course grape seed extract for a strong immune system.....
