Not to go on about this Atopic Dermatitis Research Network too much, but I had a thought. Why is this grant so big? One clue, maybe, is the story I mentioned yesterday (NYTimes version) about the 2-year-old son of a US soldier who developed eczema vaccinatum after his father was inoculated with vaccinia virus, the live smallpox vaccine.
The episode must have opened a lot of eyes to the danger this vaccine poses to eczema patients. But the NIH was aware of the problem beforehand. ADRN is the sequel to the ADVN, which was established as early as 2004 and perhaps before. Almost certainly the whole ADVN/ADRN focus on vaccines and eczema is a direct consequence of the 2001 anthrax attacks.
So, eczema sufferers, we can thank Bruce Ivins if, in a few years' time, drugs or other therapies start filtering down the pipeline to protect us against MRSA. Bioterror is big money. I don't know exactly how the NIH receives its funding, but the US civilian biodefense budget for financial year 2011 is about $6.5 billion. $32 million is peanuts. We should angle for more!
For me, although MRSA or staphylococcus in general is a continual concern, I feel that it would be a shame if a huge expenditure of research dollars removed the danger of eczema infection but left us all itching and scratching without relief. Let's not forget that.
A postscript: I asked a mathematical epidemiologist, Jamie Lloyd-Smith, an assistant professor at UCLA, what fraction of the US population would have to be vaccinated against smallpox to shut down an epidemic. His answer, which he stresses is a back-of-the envelope calculation (I leave out the math):
"You can prevent an epidemic--or eliminate an endemic disease--by vaccinating a high enough proportion of people that Reff<1. This gives herd immunity...you'd need to vaccinate 70-83% of people to eliminate smallpox."Since, including children, about 20% of the US population has experienced eczema in some form--and, say, there are three people in the average family, and even if you don't have eczema, you can't expose your child to viral danger-- it is clear that the government cannot vaccinate 70% of the population in the event of a smallpox attack without putting a small fraction at real risk of developing eczema vaccinatum. Given the loud objections of the anti-vaccination fringe to protecting their kids against measles and whooping cough--with vaccines for which the benefit overwhelmingly outweighs any imagined risk--you can imagine the trouble the government would run into if it tried to jab us all with smallpox vaccine.
