Came across an interesting news item today. It may be relevant in the context of this thread and what the C's said recently about high iron levels being a defence mechanism. Could it be that elevated ferritins are helpful in fighting off the nastier forms of influenza (maybe other stuff, too)?
This made me think - long term, iron overload is quite harmful - however, could it be useful to deliberately increase iron levels during a pandemic? If so, what would be the right methodology - iron supplements? It may well be that we need a strategy to control levels of ferritin rather than to keep them down permanently.
What do you think? Is this too much of a leap?
Also, I have found a source of EDTA which ships within Australia (eBay) - gonna bite the bullet and just do it, my energy levels are getting worse... Here's the link for those in the region:

ABC News said:New flu vaccine may protect against many strains with a single jab

A group of scientists say they have come up with a new type of influenza vaccine that may protect against various strains with a single jab.
Tested in ferrets, which are considered good human models, the synthetic vaccine uses nanotechnology to attack parts of the influenza virus that different strains have in common.
Human trials have yet to be carried out, but the team was encouraged by the extra safety of the vaccine, which does not need to be manufactured from viruses in chicken eggs in the lab, as is the case for seasonal vaccines against flu strains often carried by birds.
It is also much faster to make.
The study was conducted at the US National Institute of Allergy and Infectious Diseases (NIAID) and published online in Nature magazine.
"It provides a basis for development of universal influenza vaccines and for more rapid generation of vaccines during new outbreaks," study-co-author Dr Gary Nabel said.
The new design incorporates the protein ferritin, fused genetically with hemagglutinin (HA) - a protein found on the surface of the influenza virus.
The fusion results in a microscopic nanoparticle with eight protruding spikes that forms the basis for the vaccine antigen, which is what spurs the immune response.
Lab animals given the vaccine were protected not only against the strain of H1N1 influenza from which the HA was derived, but a broader range of strains of the constantly mutating influenza virus.
"What we did is we took a vaccine that was derived from a virus from the year 1999 and then we challenged these animals with a virus that actually had circulated eight years later in 2007, and we found that the animals were protected," Dr Nabel told AM.
"What that means is that we're generating a degree of breadth of protection that you don't see with the traditional and the current commercially licensed vaccine.
"So it's telling us right now that it's giving us better protection, better both in terms of the potency meaning how high, tighter an antibody response we get and also in terms of the breadth, meaning the number of different viruses that the vaccine can protect against."
Nothing wrong with the current vaccine
Dr Nabel says there is nothing wrong with getting the current influenza vaccine that is available.
"In fact your manufacturers and your public health system is doing exactly the right thing by encouraging people to get their flu shots," he said.
"What we're looking towards right now is to develop the next generation of vaccines.
"It may take another two to five years to get there.
"Our hope is when we do get there, that instead of getting the flu shot yearly, that we can increase the intervals between injections.
"Maybe you would get an injection once every five years in the best of all possible worlds, you know, once every 10 years with boosters occasionally."
NIAID called the concept "an important step forward in the quest to develop a universal influenza vaccine - one that would protect against most or all influenza strains without the need for an annual vaccination".
Commenting on the study, Imperial College London virology lecturer Mike Skinner said the development was "really promising", though the concept drug would need several years to pass clinical trials and regulatory hurdles.
"Although it might be more broadly effective than the current vaccines, it is too early to tell how easily or how frequently resistant viruses would arise in the future, given that candidate pandemic viruses are continually being produced in wild birds," he said.
