Posting a Diary Entry

Daily Kos welcomes blog articles from readers, known as diaries. The Intro section to a diary should be about three paragraphs long, and is required. The body section is optional, as is the poll, which can have 1 to 15 choices. Descriptive tags are also required to help others find your diary by subject; please don't use "cute" tags.

When you're ready, scroll down below the tags and click Save & Preview. You can edit your diary after it's published by clicking Edit Diary. Polls cannot be edited once they are published.

If this is your first time creating a Diary since the Ajax upgrade, before you enter any text below, please press Ctrl-F5 and then hold down the Shift Key and press your browser's Reload button to refresh its cache with the new script files.


  1. One diary daily maximum.
  2. Substantive diaries only. If you don't have at least three solid, original paragraphs, you should probably post a comment in an Open Thread.
  3. No repetitive diaries. Take a moment to ensure your topic hasn't been blogged (you can search for Stories and Diaries that already cover this topic), though fresh original analysis is always welcome.
  4. Use the "Body" textbox if your diary entry is longer than three paragraphs.
  5. Any images in your posts must be hosted by an approved image hosting service (one of: imageshack.us, photobucket.com, flickr.com, smugmug.com, allyoucanupload.com, picturetrail.com, mac.com, webshots.com, editgrid.com).
  6. Copying and pasting entire copyrighted works is prohibited. If you do quote something, keep it brief, always provide a link to the original source, and use the <blockquote> tags to clearly identify the quoted material. Violating this rule is grounds for immediate banning.
  7. Be civil. Do not "call out" other users by name in diary titles. Do not use profanity in diary titles. Don't write diaries whose main purpose is to deliberately inflame.

Please begin with an informative title:

This is still very early research, but it's worth passing along.

An international team of scientists has reported impressive results in their first animal trial of a new vaccine that might be applicable to HIV, the virus that causes AIDS. In monkeys, the equivalent virus is called SIV (Simian Immunodeficiency Virus) and it's a close cousin to HIV, the human version.

Using a surprisingly simple formulation (or actually three similar formulations), French and Chinese researchers were able to prevent SIV infection in 23 of 24 macaques getting the vaccine, for at least four years. In the control group, all 24 monkeys were infected.

The vaccine works by deliberately suppressing a portion of the immune system, the part that triggers a response by CD4 T-cells. The CD4 cells are the target of the HIV virus (and the SIV virus), and when an infection occurs the resulting spike in CD4-T production just provides the virus a lot more hosts to infect. The CD4 trigger is suppressed in part by including standard "good" bacteria in the vaccine, of the kind seen in probiotics found in any health food store. Somehow, this allows the virus to escape the notice of the CD4 triggering mechanism.

Instead, the vaccine stimulates a minor player in the immune system, the CD8 T-cell.
