Nova Laboratories Ltd. and Oxford University are trumpeting a new method to make vaccines shelf-stable, essential if they're to become commonplace in tropical climates.
Vaccine man Bill Gates is probably smiling today.
The paper on the method was approved last month and is online at the Science Translational Journal.
The Hypodermic Rehydration Injection System (HydRIS) starts by mixing live vaccine with two sugars -- simple sucrose and trehalose, which is often used to stabilize processed foods. This is dripped onto a membrane of glass fibers, then dried in low-humidity, at room temperature.
The process lets the sugars form a noncrystalline solid around the membrane, and thus around the vaccine. This prevents contamination -- vaccines can be stored at body temperature and higher for months, in other words in tropical heat. Releasing the vaccine is as simple as flushing it with salt water, simple saline.
Nova, which holds the patent on the process, has also developed a cartridge that allows the vaccine to be rehydrated and injected at the same time, without exposing it to the air. The company also has aseptic manufacturing technology, and enough capacity to produce vaccine for clinical trials.
This is a very big deal. Principal investigator Adrian Hill explained:
The World Health Organization's immunisation program vaccinates nearly 80% of the children born today against six killer diseases: polio, diphtheria, tuberculosis, whooping cough, measles and tetanus. One of the biggest costs is maintaining what's called the cold chain -- making sure vaccines are refrigerated all the way from the manufacturer to the child, whether they are in the Western world or the remotest village in Africa. If most or all of the vaccines could be stabilized at high temperatures, it would not only remove cost, more children would be vaccinated.
The work was funded by Britain's Wellcome Trust.

Well, I thought it was interesting. And certainly, the less mercury is used anywhere, the better. But are you going to give up your car, cell phone, computer, and anything else made from poisonous metals and petrochemicals? You realize, most vaccines do not have Thimerosol in them, correct? And (let's just use your number since you offered it) 50 ppm in a vaccine solution is not 50 ppm in your body. Not even close. Not within several orders of magnitude. "Studies at UC-Davis show damage to dendrites and calcium channels, perversely harming immunity," Now, I've seen similar statistics waved about in other fora, but I'm finding nothing in peer-reviewed literature that quite matches these claims. So, if you'd care to cite your sources, let's have 'em. The only summary of a study I can find, not done at UC Davis, which comes close at all has this: "Exposure to thimerosal at concentrations as low as 20 ppb altered the time course of these responses, however, and prolonged the length of time that intracellular calcium levels remained elevated. One possible consequence of these sustained calcium levels is a change in the rate and timing of cells' secretion of interleukin-6, a chemical that triggers further immune system action" And this doesn't exactly last forever, either.
But thimerosal is not behind the rise in autism. That claim was false. It was a phony study that has been turned into a political cult. Vaccine opponents love to disparage the motives of vaccine doctors -- they're only in it for the money -- but did you ever once consider the motives of the idiots you follow? It is past time for this nonsense to stop.
Does this mean the mercury-based preservative Thimerosal can finally be removed from vaccine manufacture once and for all? Chemists state that even if Thimerosal is chelated post-production, as is current practice, a certain amount remains bound to the antigen. Or in the case of most injected flu vaccines, 25 micrograms remains (50,000 parts per billion). Studies at UC-Davis show damage to dendrites and calcium channels, perversely harming immunity, at rates as low as 20-40 ppb.
