This whole vaccination thing is strange to me. I have never been one that was afraid of needles or vaccines. Usually, when a needle was stuck in me, there wasn't really much choice. Get the shot, get better, or not do so & suffer the consequences.
Reminds me of my Army days, where in basic training, we were told to line up & go thru the gauntlet of medics on each side with the spray paint gun type injection apparatus. Roll up your shirt sleeve & get hit on both sides at the same time. No option. Never saw anyone raise their hand to opt out.
Again, when we were preparing to leave for Vietnam, more of the same. No choices. Then there were the Malaria pills.
I have no idea what was in these vaccines, never gave it a thought.
Thing was, I never contracted any of the numerous diseases to be had. I also used the dreaded iodine tablets in my canteen. Tasted like crap, but you lived with it.
I've never suffered any ill effects from any of it.
