Parents often ask this question because they wonder how many antigens (substances that induce an immune response) the body can cope with.
While these are reasonable questions, the answer is that by the time a child is 6, vaccines account for around 0.006% of the total antigen exposure of the child.
As this video by ‘Academic Earth’ illustrates, vaccines represent a miniscule proportion of the total natural antigens and organisms that people encounter in their daily lives.
“Worrying about the exposure from the vaccine schedule is like worrying about a thimble of water getting you wet while swimming in an ocean.”
