The study finds that the antibodies, as though tempered to greater toughness by time, have mutated steadily in ways that enhance their potency.

I've done more searches looking for natural immunity from smallpox, but have found contradictory information. Some say there is no "natural immunity." Some have said it exists, but it is rare. Still others suggest some must've had light exposure to the virus (or something to that effect.) I've posted a question about this with the hope of clearing this up.

BTW, I remember reading an article like this, about the influenza antibodies, and how long lasting they were.

I remember watching a show over a year ago ...maybe on NOVA or National Geographic Channel about the offspring of the survivors of the Black Plague which wiped out 50% of Europe in the 1300's? as they were analysing their DNA for clues as that was interesting.

Something that was eery was when i worked at an apartmernt complex years ago and we had to go into the attics of this very old complex to work on the HVAC Evaporators and right directly above about 3 feet away as you couldn't stand up in there you could see all the bats hanging upside down sleeping with our flashlights. They must have got in thru the sewer vent pipes going thru the roofs where there were small holes and cracks etc..

There was another Nova show having to do with transgenerational epigenetic changes due to such environmental pressures such as famine or the like. The idea is that there is no change in the DNA, itself, but that the way genes are expressed has changed. Now, this may be something of a stretch to suggest that this affects a persons ability to handle disease, one way or the other, but who knows?

Yeap i saw that show as it looks like its the Epigenome and not the Genome that sets our ability to contract certain diseases and also our bodies reactions to the enviroment and our diet. That's why identical twins can have different diseases and life spans.

Although the scientists said they are going to start animal trials with it and try to perfect it in humans.
Incorrect. To date, I believe it's SIX known survivors.

Hey, that's good to hear. I hope they learn something from these people.

You are correct as i should have been more specific that there are 6 survivors of rabies but they did recieved the Vaccine after the first symptoms where as Jeanna Giese is the only human being ever to survive rabies with no Rabies Vaccine at all.

Jeanna Giese - Wikipedia, the free encyclopedia

Since the immunity issue was mentioned re smallpox, I thought I'd post this from my inbox:
Thank you for your inquiry to CDC-INFO. In response to your request
for information on vaccines, including immunity to smallpox, please refer
to the following information.

Someone who was vaccinated against smallpox decades ago may retain some
immunity but it is not known for certain that this level of immunity
would protect them from smallpox today if exposed. Information on a
naturally occurring immunity to smallpox not occurring through an active
infection was not identified in CDC resources.

Cell-mediated immunity most likely plays the primary role in the
recovery from smallpox infection. Antibodies play a secondary role in
recovery, though they play a primary role in protecting against re-infection.
The presence of viral neutralizing antibodies is considered a
reasonable marker of immunity.

Epidemiologic studies demonstrated that a high level of protection
(nearly 100 percent) against smallpox persists for up to 5 years after
primary
vaccination and substantial but waning immunity for ten years or more.

Vaccines interact with the immune system and often produce an immune
response to a specific disease similar to that produced by the natural
infection, but they do not subject the recipient to the disease and its
potential complications. Vaccines produce immunologic memory similar to
that acquired by having the natural disease.

Many factors may influence the immune response to vaccination. These
include the presence of maternal antibody, nature and dose of antigen,
how the vaccine is given, and the presence of adjuvants (materials added
to improve how well the vaccine works).

Host factors such as age, nutritional factors, genetics, and coexisting
disease, may also affect the response.

More information about vaccines and how they work is available in the
following:

Understanding Vaccines (PDF)
http://www.niaid.nih.gov/publication...df/undvacc.pdf

Understanding the Immune System (PDF)
Immune System, NIAID, NIH (http://www3.niaid.nih.gov/topics/immuneSystem/default.htm - broken link)

If your friends are concerned that they are not protected against
vaccine-preventable diseases, please encourage them to speak with their
doctors.

For more information about vaccines and about smallpox, please visit
the CDC website:

I didn't realize rabies was so deadly.

A lady working for our cat's vet was scratched by a cat some months ago. The cat was put into a cage, of course, until they could make sure it didn't have rabies. I suppose his assistant had to get shots. The vet is very adamant about rabies vaccinations shots for all pets.

Personally, I'd avoid contact with any suspicious animals like the plague, especially after reading the above posts.
