SSPE – a dangerous complication from not getting the measles vaccine

One of the tropes of the anti-vaccine religion is that childhood diseases, like measles or whooping cough, are not dangerous. But real science tells us that measles complications, like SSPE (subacute sclerosing panencephalitis) and death, are not innocuous. The ignorance about measles puts our children at risk.

Sadly, some of these vaccine-denying parents have set up “pox parties” to deliberately expose their children to these diseases, because they believe that natural immunity is better than vaccine-induced immunity. Not only is that an appeal to nature fallacy, but it shows ignorance on how immunity works.  Continue reading “SSPE – a dangerous complication from not getting the measles vaccine”

Infant T cells don’t remember pathogens–causes weaker immunity

active-immunityIf you hang out in various vaccine discussions, you will hear all kinds of odd, unscientific ideas about the immune system of infants. One of the major issues is a substantial oversimplification of the immune system (of adults and infants), mostly thinking it’s one “thing,” ignoring the complex physiology of the immune system which is an almost infinite number of interactions between cells, proteins and factors, organs, blood, fluids, and other physiological systems.

Generally, the popular assumption is that the infant immune system is weak, making those children more prone to viral or bacterial infections. The antivaccine crowd uses this belief to either state that vaccines won’t work or might actually harm the immune system, along with some overstated magical properties of human breast milk to prevent infection.

But according to a new study, led by Dr. Brian Rudd of the Department of Microbiology and Immunology at Cornell University, published in the Journal of Immunology, the immune system of newborns and infants is actually stronger than an adult’s immune system. Unfortunately, it has a short “memory.” Continue reading “Infant T cells don’t remember pathogens–causes weaker immunity”
