As a child when one of us kids caught something we were all placed together so we all caught it and it built up our immune systems and we never caught it again. When they first pushed for vaccines (polio) one of my siblings received the shot and there started her life long battle with her immune system. The rest of us had to be inoculated at least 3 times because their "shots" did not work on us, our immune systems were built up against whatever was in the shot. Only 1 time have I ever received a flu shot and I was sick for over a year from it, I am not knocking modern medicine and know there are places for it but I quit having any faith in their chemical cocktails to heal most issues and prefer my herbals that work with my body and not fight my body to get back into wellness. Great topic so will share it.
