By having any vaccines,you have a chance,albeit small,of getting a rare illness called Guillian-Barre Syndrome,which totally paralysed me,and had me on ventilaters,etc.in the I.C.U over 6 weeks.I did not get it from a vaccine(,likely from bacteria on poultry),but I could get it again,if I take any vaccines.Look up- Guillian-Barre syndrome and vaccines-knowledge is power.
