This article does not in any way show evidence for the whooping cough vaccine causing children to develop whooping cough. If you read the full
article, you will see that 74 children had received the recommended 5 doses of the vaccine and 68 had received one more than this amount, which is 79%
of all the children who contracted the disease in the outbreak, whereas according to
70 percent of vermont children receive "every vaccine in the recommended series".
Note this is a lower bound, it could be that a further number of children had the DTaP vaccine (the one that protects against whooping cough,
diphtheria, and tetanus).
So at most we have that 79% of the children with the disease had been vaccinated versus 70% of the children who had not gotten the disease being
vaccinated. With a group of only 178 children contracting the disease, this is not significant enough to show any probable relation between having
gotten the vaccine and contracting the disease (though it doesn't show the vaccine causing any protection, either).
Diseases are caused by cells with have markers on their surface. When you're exposed to a disease your body sees the markers and creates cells that
"remember" them, so if it sees those markers again those cells will make your body produce other cells that search for and destroy the disease
cells. Long story short, your immune system has a "memory". It turns out, the memory the DTaP vaccine gives your immune system doesn't stay there
for very long. According to the article:
"The problem with DTaP, as a study published last month in the New England Journal of Medicine shows, is that the vaccine loses its effectiveness.
The study compared 277 children, ages 4 to 12, and found that a child’s odds of contracting pertussis increased 42 percent every year after the
TL;DR: this is not an example of a vaccine causing children to acquire a disease. However, remember that vaccines do not (and also do not claim to)
make it impossible for you to contract a disease.
