New Ebola vaccine shows 100% success rate in clinical trial. Today the World Health Organization has announced that the rVSV-ZEBOV vaccine had a 100% success rate in preventing onset of the disease if administered within 10 days of exposure (n=4,000). In response to the current outbreak in West Africa that has afflicted over 27,000 and killed over 11,000, this collaborative effort led by the WHO pushed the vaccine through a process that usually takes more than a decade in just 12 months. Official paper from The Lancet here (pdf).
"During the 2013-2014 flu season, according to the Centers for Disease Control and Prevention, only 46 percent of Americans received vaccinations against influenza, even though it kills about 3,000 people in this country in a good year, nearly 50,000 in a bad one." [more inside]
A timeline of diseases and vaccines [warning: graphic photo of cutaneous diphtheria at year 1975]. Categories are: diphtheria, measles, polio, smallpox, yellow fever, and 'others'. You can select one keyword to view only that subject's timeline. From the History of Vaccines website (about page | FAQ). Similar timelines at the same site for pioneers, science and society, and there's an En Español timeline, too. [more inside]
"Why do parasites harm their hosts? Conventional wisdom holds that because parasites depend on their hosts for survival and transmission, they should evolve to become benign, yet many parasites cause harm. Theory predicts that parasites could evolve virulence (i.e., parasite-induced reductions in host fitness) by balancing the transmission benefits of parasite replication with the costs of host death. This idea has led researchers to predict how human interventions—such as vaccines—may alter virulence evolution, yet empirical support is critically lacking." Two papers demonstrate empirical evidence for related models predicting the origin of virulence: [more inside]
A new malaria vaccine has been shown effective in large-scale field trials. After decades of disappointment, researchers think they're finally on track to unleash the first practical vaccine against malaria, one of mankind's ancient scourges. In the world's first large field trial of an experimental malaria vaccine, several thousand young children who got three doses had about 55 percent less risk of getting the disease over a year than those who got a control vaccine against rabies or meningitis.

Recently, 8-year-old Precious Reynolds became the sixth person in history to survive rabies without a vaccine. A few years back, Extraordinary People put out a documentary (1 2 3) on the first person to beat the only viral disease that hides itself completely from one's immune system.
Hannah Poling is a nine year old girl with mild to moderate symptoms of autism, which developed three months after she received vaccinations. The Department of Health and Human Services announced that her family will receive a settlement from the vaccine compensation fund. Autism activists are encouraged, but the DHHS officials insist they are not admitting a link between autism and vaccines and maintain that for most, vaccines are safe. Rather, they say, the series of vaccines Hannah received exacerbated an underlying mitochondrial condition, causing the symptoms of autism. [more inside]
Newsfilter: Several pharmaceutical companies are developing vaccines against strains of the human papilloma virus that cause cervical cancer. Some folks think these shots should be required for all kids entering puberty. Others are afraid that teens given the vaccination would view it as a free pass for premarital sex.
Smallpox Vaccination? The New England Journal of Medicine made available today an early release of articles from their planned January 30, 2003 issue, designed "to help inform the current national debate about smallpox vaccination" [more inside....articles unfortunately available only in PDF....]

Immortality Protein May Offer Cancer Vaccine. You know, I'm glad they're making progress, but once the 'cure' is found, I can't daydream about being this smart, intelligent doctor, (something right out of a soap), that creates the cure for cancer, and woos all the la-a-dies... then again there is always being that evil-twin and start cloning, with that, you won't need to wooo anyone, they're your toys! mwahahaha!
