No child is born with an intact immune system. During the first 2 years of life the immune system is trying desperately to organize. Despite extravagant claims by the medical community, how that immune system is actually assembled by the body is still largely unknown.
We could study our entire lives and barely scratch the surface of God’s design.
What IS known for certain is that subjecting the infant’s immune environment to an array of man-made pathogens, preservatives, and adjuvants absolutely can have a deleterious [harmful; injurious] effect on the formation of that child’s brain and nervous system. All scientists – including the vaccine manufacturers – admit as much. Doctors ARE speaking out.
For more information, I highly recommend watching The Truth About Vaccines series.
