iBio's ($IBIO) shares have jumped 21% with the announcement that it has completed the first Phase I clinical trial of its plant-based vaccine for H1N1 influenza, HAC1. The study of the vaccine, produced by iBio's partner the Fraunhofer USA Center for Molecular Biotechnology, aimed to assess the vaccine's safety, as well as looking for early clues to its ability to trigger an immune response against the flu virus. The study showed that the vaccine was safe and well-tolerated at low and high doses, regardless of whether an adjuvant was used. The vaccine also triggered immune responses, with the best immune response seen in the people who received the highest dose of the vaccine without an adjuvant. This was a similar response to a marketed flu shot.

Here we report the detection of serological responses against EBV capsid antigens in healthy dogs and dogs with spontaneous lymphoma and that dogs with the highest antibody titers have B cell lymphoma. Moreover, we demonstrate the presence of EBV-like viral DNA and RNA sequences and Latent Membrane Protein-1 in malignant lymph nodes of dogs with lymphoma. Finally, electron microscopy of canine malignant B cells revealed the presence of classic herpesvirus particles. These findings suggest that dogs can be naturally infected with an EBV-like gammaherpesvirus that may contribute to lymphomagenesis and that dogs might represent a spontaneous model to investigate environmental and genetic factors that influence gammaherpesvirus-associated lymphomagenesis in humans.
VERY interesting...a most unexpected place to find a useful human model for herpesvirus disease!

Uptake of the human papillomavirus (HPV) vaccine among the private medical profession has been dismal, leading to unnecessary deaths every day, according to Johannesburg gynaecologist and obstetrician, Dr Peter Koll. “Penetration into the target patient population has been huge elsewhere in the world – up to 80% in some European countries. In SA, it is certainly under 5% and probably as low as 2%,” he said. Considering that one in 20 women in this country who receive the HPV vaccine will be saved from cervical cancer, the second most prevalent cancer among women in SA, Dr Koll finds it hard to understand the lack of will among private doctors to protect their patients from the disease.
Of course, the fact it COSTS so much to vaccinate against HPVs could have something to do with the lack of uptake??

An anti-polio vaccine, being used in India since 1978, could be shelved soon. The India Expert Advisory Group (IEAG) on polio has recommended that the nation should stop the use of trivalent oral polio vaccine (TOPV), and only rely on the oral bivalent variant. Experts say chances of vaccine derived polio virus infection (VDPV) are higher with the use of TOPV (that targets all three strains of polio virus - P1, P2 and P3) against the bivalent vaccine (that targets only P1 and P3). However, the World Health Organization (WHO) will take a final call in April after the meeting of its Strategic Advisory Group of Experts (SAGE) on Immunization.
Makes sense: if you have no polio, using a live vaccine that is associated with reversion to virulence is not smart.

Public-health officials are increasingly worried about potential outbreaks of measles, whooping cough and other diseases in parts of the country where vaccination rates are dangerously low. Health experts say a community needs about 95% of its citizens to be immunized against measles to ensure herd immunity, where vaccinating a large percentage of a population keeps even unvaccinated people from getting the disease. Even people who aren't vaccinated, such as newborns, get some protection from herd immunity as the disease remains limited to a small part of the community.

A deadly bird flu virus that was made transmissible in mammals, touching off public fears of a pandemic, is not as contagious as people had been led to believe.
I note in particular: "In addition, he [Ron Fouchier] said, if the ferrets were previously exposed to a run-of-the-mill seasonal flu, they were immune to the bird flu."
But this too: "...a member of the biosecurity board, warned that ferrets were not a perfect model for what would happen in humans, and that it was impossible to tell how virulent or contagious the new virus would be in people."
So first ferrets show how lethal the virus will be - and then they don't?? Some people want it all ways....

Mayo Clinic researchers have trained mouse immune systems to eradicate skin cancer from within, using a genetic combination of human DNA from melanoma cells and a cousin of the rabies virus. The strategy, called cancer immunotherapy, uses a genetically engineered version of the vesicular stomatitis virus to deliver a broad spectrum of genes derived from melanoma cancer cells directly into tumors. In early studies, 60 percent of tumor-burdened mice were cured in fewer than three months and with minimal side effects. Results of the latest study appear this week in the journal Nature Biotechnology.

Among other things, Baratunde Thurston is a social and political satirist. So in 2009, when paranoid fervor about the disease formerly known as the Swine Flu was at its height, he masqueraded as the Swine Flu on Twitter and Facebook. With their angry pig icon and badass attitude, Baratunde's swine flu accounts quickly (yes, I said it) went viral, getting write-ups in major media outlets like The Huffington Post and prominent followers like (someone explain this please) Mitt Romney. Much of the experiment's success was the result of Baratunde's energy and inventiveness in enacting the disease across various platforms.

Respiratory Syncytial Virus (RSV) is a common virus that infects the lungs and breathing passage ways. Though it may only produce minor cold symptoms in adults, it can lead to serious illness in young children and those with compromised immune systems.... According to the Centers for Disease Control, RSV is the leading cause of bronchiolitis, an inflammation of the small airways in the lung, in infants under the age of 1. Most children will have been exposed to RSV by their second birthday.

Late last year came word that a Dutch scientist had genetically tweaked one of the world's most deadly bird flu viruses to make it more contagious to humans. In other words, a doomsday virus in a sneeze that could kill more than half of the people who caught it.That chilling revelation set off an international furor over whether the details of that study and a similar one done by researchers at the University of Wisconsin at Madison should be published in scientific journals. Scientists argued that researchers need those details to better detect and fight a possible epidemic of the virus, known as H5N1. Security experts argued compellingly that the studies should be expunged of key details, lest terrorists use that information to unleash a devastating biological weapon.

While there has been a great deal of attention focused on making sure children receive required vaccinations, Minnesota medical professionals and health advocates are becoming more concerned about a growing number of people over the age of 18 who are not getting vaccinated.The majority of immunization awareness campaigns urge adults to get their children vaccinated, but the fact is that most people who die from vaccine-preventable diseases are actually adults. In the U.S., approximately 50,000 adults die each year from vaccine-preventable diseases.

"We want people to have informed choice when it comes to vaccines." These words, or at least something along these lines, are uttered by many anti-vaccine activists, like Barbara Loe Arthur (aka Barbara Loe Fisher) of the misnamed National Vaccine Information Center or the authors at Age of Autism. To hear them speak, you would imagine that they would be completely in favor of any efforts which strive to provide accurate, complete information to parents who are deciding whether or not to have their children vaccinated. Such efforts should be whole-heartedly embraced by these "pro-informed consent" warriors.
There are something like THREE HUNDRED THOUSAND anti-vaccination web sites right now. Boycott one today!

A genetic marker that may protect some people against HIV infection has been found, a new study from researchers in France suggests. This genetic marker occurs less frequently in people infected with HIV than in people who do not have the virus, the study showed. If confirmed, it would be the second genetic marker ever found to give people some resistance to the infection that causes AIDS. The only such marker known to date is a particular mutation in a gene called CCR5. This gene, which is found in about 1 percent to 2 percent of people of European decent, provides near-complete protection against HIV infection, the researchers say.

A newly discovered virus may be one of the causes of a potentially fatal kidney disease in pet cats. Tubulointerstitial nephritis is a disease that inflames the spaces between the kidney tubules, the tubes that carry fluid for filtration inside the organ. Many factors can cause tubulointerstitial nephritis in humans, from infections to autoimmune disorders to certain medications. But in cats, the cause is rarely known.

Chemists have produced the first high resolution structure of a molecule that when attached to the genetic material of the hepatitis C virus prevents it from reproducing. The structure of the molecule, which was published in a paper in this week's early online edition of the journal Proceedings of the National Academy of Sciences, provides a detailed blueprint for the design of drugs that can inhibit the replication of the hepatitis C virus, which proliferates by hijacking the cellular machinery in humans to manufacture duplicate viral particles.

The University of Florence has launched an inquiry into the teaching activities of an academic who assisted on a course that denies the causal link between HIV and AIDS, and supervised students with dissertations on the same topic. The Italian university's internal 'special commission' will examine the “teaching behaviour and responsibility” of molecular biologist Marco Ruggiero, a university spokesman told Nature. The move follows a letter to the institution's rector, Alberto Tesi, by an Italian campaign group called the HIV Forum, which represents people infected with HIV and others concerned about the disease. It calls on him to disassociate the university from the “science and activities” of Ruggiero, who, the group says, is “internationally known” for denying the widely accepted link between HIV and AIDS, and promotes a potential cure for HIV involving an enriched probiotic yoghurt for which there is no proven evidence.
Very dangerous people...you have to wonder how they maintain such denial in the face of so much evidence?

The 6-year-old shingles vaccine is one of the newest immunizations on the market and also one of the most popular, which has created a persistent manufacturing shortage. The shortage surfaced almost immediately after the Centers for Disease Control and Prevention recommended that most Americans over age 60 get vaccinated to prevent shingles. The vaccine, licensed in 2006, can prevent shingles, a painful skin rash that often appears with blisters. In clinical trials, the vaccine prevented shingles in about half of people 60 years of age and older, according to the CDC. The vaccine can also reduce the pain associated with shingles.
