I strongly disagree with your opinion, as I feel there is no vaccine in this world that is safe and helpful. From my extensive research, I found numerous clues that led me to conclusion that every single disease we know today is man made.
On the other hand, I respect your opinion and I'm thankful because you shared it with me. I hope we will reach better agreement in the future, on some other cases ^^
Peace be with you and have a lovely day
