How can the &quot;president&quot; declare H1N1 a national emergency but will not vaccinate his children?</description>

		<description>I&#039;m sure we will probably never agree on this, but here goes:
The guidelines for mercury compound are exposure are daily doses, i.e. this is daily exposure not 1 or 2 single exposures. Mercury accumulates over time so the limit could be significantly less than the toxic dose because it would reach there eventually. 
It&#039;s exactly the same as the guidelines for radiation exposure. It might be perfectly fine for you or me to get an X-ray but the radiologist who does this every day has to stand in the other room. The radiation from some procedures such as CT-scans can be hundreds of times that of the X-ray so far in excess of what the radiologist could receive on a daily basis but its okay for the patient because they only get 1 or 2 exposures.
Back to mercury, look at the last paragraph under thiomersal toxicity on the FDA page you cited:http://www.fda.gov/BiologicsBloodVaccine…
Mercury from thiomersal undergoes more rapid clearance from the blood than other compounds. This will alter the steady state it would reach even from repeated doses. 
It is my understanding that mercury toxicity has a threshold effect, do you have evidence that the small quantities in 2 flu shots could reach the required toxic level? The toxic doses of thiomersal on the FDA page seem far too high for this.
Since thiomersal is cleared faster from the system shouldn&#039;t we be more concerned with other organomercury compounds such as methylmercury from fish? These are easily in the same range as the vaccine doses and unlike the shots are repeated over time. If mercury exposure was to have a cumulative toxicity, that&#039;s where I&#039;d expect to see it (and not just with severe contamination like Minamata).
Additional:
Good question: why did they move remove thiomersal from pediatric vaccines?
This sums it up pretty well:
&quot;Limited data on toxicity from low-dose exposures to ethylmercury are available, but toxicity may be similar to that of methylmercury. Chronic, low-dose methylmercury exposure may cause subtle neurologic abnormalities. Depending on the immunization schedule, vaccine formulation, and infant weight, cumulative exposure of infants to mercury from thimerosal during the first 6 months of life may exceed EPA guidelines.&quot; (1)
I&#039;m not claiming that it was a bad decision, but there are couple of issues you need to consider before generalising to the flu shots. 
Firstly, this is based on methylmercury, which as we have established has different properties. Children receive a lot of vaccines in their first 6 months of life, so cumulative toxicity had to be taken into account. Methylmercury lasts longer in the system so the cumulative effect is greater than for ethylmercury. 
Analysis found (using methylmercury) that the cumulative dose may exceed EPA guidelines, but not ATSDR, FDA, or WHO guidelines, which have a higher limit (1). This is because EPA guidelines contain up to a 10 fold safety factor (1).
In conclusion, everything is toxic at the right dose and kids shouldn&#039;t be exposed to mercury over a certain threshold. If childhood vaccines did contain mercury, it&#039;s possible that the cumulative dose would exceed recommendations for methylmercury exposure but only according to the EPA. As ethylmercury is cleared faster the actual cumulative dose is lower anyway, making it only a theoretical risk.
Once again, this is for cumulative exposure, since children receive lots of paediatric vaccines in a short amount of time. Children will receive a maximum of 2 shots for the pandemic virus. The mercury is only present because they need multi-dose vials in a pandemic situation. This is the first flu pandemic in 41 years. There is no potential for cumulative toxicity.</description>
