Hi Cyn - thanks for sharing that information. I'm finding this a very interesting discussion. Because.....when a vaccine is administered, it is really a small dose of the disease and only makes the animal (or person) "slightly" sick but stays in their system so that they build immunity to that disease. So why wouldn't being exposed to a live/real disease and surviving (for whatever reason) not do the same? Why wouldn't they just now be immune and not "carriers" in the aspect that someday they are going to show symptoms and/or spread it to others? I'm not sure which way I'm swaying on this topic but I'm tending to sway to the side that says they would be immune and pass that immunity on to their chicks. Same way a mother passes her immunities onto her children.
Another, for example, as I said, I've never been sick. I breastfed my son, who not only has never been sick, he never got any of the childhood diseases and never got the commonly occuring ear or sinus infections, colds, bronchitis, - nothing - ever. He's now 27 and home for a visit from his tour in Iraq.
And speaking of my son, the soldier - it seems the army keeps messing up his records, especially his medical records and shot records. So, he's had to have the same shots and vaccines dozens of times including being shot full of every third-world disease and antrax on multiple occasions - never got sick.
I'm now of the opinion - "That which doesn't kill us makes us stronger."
