which act as huge reservoirs for the virus at bird vaccination centres and at cock fighting contests.
and transmissibility of these H7n9 viruses and to develop effective vaccines and antiviral drugs so as to reduce their adverse effects upon human health.
The researchers led by Ram Sasisekharan the Alfred H. Caspary Professor of Biological Engineering at MIT also found that current flu vaccines might not offer protection against these strains.
From a pandemic-preparedness point of view we should potentially start including some of these H3 strains as part of influenza vaccines.
The researchers then exposed some of these strains to antibodies provoked by the current H3 seasonal-flu vaccines.
whether or not to use vaccination to contain this disease so as to reduce the likelihood of exposure of humans to the H7n9 virus. APEIR studies on policy development showed the importance of having sound evidence on the merits
and pitfalls of vaccination so that these can be weighed up scientifically without outside interference. Although there is no evidence so far that this virus will result in a human pandemic this outbreak provides a reminder of the importance for all countries to ensure they have an appropriate stockpile of antiviral medication.
Developing a vaccine for the Schmallenberg virus is a possibility. One already exists for the similar Akabane virus
which kills round 40000 people each year with no vaccines or specific treatments currently available. There have been around 2400 cases of dengue infection in Northern Australia in recent years.
One major question raised by the finding is why the Hepatitis a vaccine works so well to contain the infection.
The vaccine one of the most effective in use was thought to elicit neutralizing antibodies that attack the virus in the blood.
Since it is known now that the envelope surrounding the virus in the blood prevents this the vaccine cannot work as previously thought.
It makes us rethink completely the mechanism underlying the well-documented efficacy of Hepatitis a vaccine.
Future studies will investigate the mechanisms behind the vaccine's effectiveness Dr. Lemon said. While it was thought previously that vaccine-induced antibodies attacked the virus outside of the cell the new findings suggest antibodies may actually be able to restrict viral replication within a cell.
Understanding how this really good vaccine works will help us in the future to develop better vaccines for other viruses that we are having difficulty developing vaccines for said Dr. Lemon.

It seems that T-cell aggregation is a profound part of the reason. Krummel's team found that the critical differentiation period is essential to the formation of
Without that long-term memory vaccines would be said useless Krummel. The body wouldn't remember that it had been exposed to a particular pathogen such as measles
In experiments with a mouse model of human immune function the scientists vaccinated mice for listeria a common bacterium that causes food-borne illness
as if the mice had never been vaccinated at all. Krummel said the work also opens up new paths of research in immunology
experts sayscientists say amending an EU directive on GMOS could help stimulate innovation in making cheaper vaccines pharmaceuticals
This could be of huge benefit in developing countries where problems with storage can render vaccines useless.
#Poultry vaccination responsible for dramatic fall in Salmonella infectionsmass poultry vaccination programmes introduced to combat Salmonella infections have led to a dramatic fall in the number of cases since the late 1990s according to a researcher at the University of Liverpool.
and disinfection procedures as well as a voluntary industry-led vaccination scheme that began in breeding flocks in 1994 and in laying flocks in 1998.
but the mass vaccination of poultry has continued by those breeders subscribing to the Lion Quality Code of Practice
The code of practice requires mandatory vaccination of all young hens destined to lay Lion eggs against Salmonella as well as traceability of hens eggs
Sarah O'brien Professor of Epidemiology and Zoonoses from the University's Institute of Infection and Global Health attributes a dramatic fall in the number of Salmonella cases in humans to this mass vaccination programme in poultry.
The decrease in laboratory confirmed human cases coincides quite closely with the introduction of vaccination programmes in breeder and laying flocks.
but the relationship between vaccination programmes and the reduction in human disease is compelling and suggests these programmes have made a major contribution to improving public health.

This milk vaccination was a success. The piglets of infected sows exhibited a less severe development of the disease than piglets of non-infected sows.
#Vaccinating cows could answer serum shortageby many estimates an Ebola vaccine could be available in humans as early as next year.
There are a number of vaccines in development and each is in a race to prove that it is most effective safe
One promising Ebola vaccine is based on a human rabies virus vaccine and is developed by Thomas Jefferson University in collaboration with the National institutes of health (NIH).
This novel vaccine could not only help reign in the current epidemic in West Africa but could be expanded easily
The researchers also plan to develop the vaccine into the type of antibody serum therapy used in the first U s. recipients in a platform that could deliver at least 2000 doses of potentially lifesaving serum per month.
Vaccines are the best way to completely eradicate an epidemic threat like Ebola says Matthias Schnell Ph d. Director of the Jefferson Vaccine Center and Professor of Microbiology and Immunology at Thomas Jefferson University.
Dr. Schnell and his team have developed a vaccine that activates the immune system to produce large amounts of antibodies against three virus strains
Already Dr. Schnell's group has developed the vaccine which showed good protection in nonhuman primates against the Zaire Ebola virus.
Currently the vaccine is being developed with the help of Peter Jahrling at the Integrated Research Facility at the NIH
and with IDT a company that prepares human-grade vaccines. Although the current timeline would have the shots ready for trials in two to three years Dr. Schnell says that a vaccine could be ready in six to ten months
if appropriate investments were made. Vaccines however may only prevent the spread of the disease rather than help those who have contracted already the infection because of how quickly the disease progresses.
In order to address this issue Dr. Schnell is working with another company with a novel method of producing antibodies en masse.
Although they do not confer the long-lasting immunity of a vaccine antibodies attach to virus particles
Together with SAB Dr. Schnell is applying for a grant that would allow the team to vaccinate the cows with his vaccine in order to produce large quantities of antibodies specific for the three viral strains.
The cows would have harvested their blood plasma every two weeks to produce 30-60 liters of serum every month from one animal--the equivalent of 2000 doses. The vaccinated cows would produce polyvalent antibodies--antibodies that can recognize many
Their computer simulations may lead to new strategies to stop influenza perhaps even a one-size-fits-all vaccine.
Such agents could lead to a universal flu vaccine that would last a lifetime. He said the membrane fusion mechanism is shared widely among many biological systems
and changes next-generation sequencing can be used to help update vaccines so they are still effective Hause said.
Then we can mine that dataset to match the vaccines or to get additional information on the pathogen.
#Developing better vaccine for mutating virus in cowsbovine viral diarrhea virus infections result in one of the most costly diseases among cattle with losses in U s. herds estimated at $2 billion per year according to professor Christopher
Most cattle producers vaccinate yearly but when testing is done anywhere from one to 15 percent of a herd can test positive.
This makes developing a vaccine to prevent the virus challenging. Triggering immune responsethrough a five-year SDSU-USDA Experiment Station grant Chase his colleague immunology expert Alan Young
The ultimate goal is to develop better modified live vaccines. Hoppe's unique microscope setup allows the researchers to use fluorescence to see what's happening at a molecular level in live cells.
They surmise that different virus strains will require different vaccine strategies. Ultimately the best kind of immunization would be to increase the mucosal immune response antibodies secreted on the surfaces of the throat gastrointestinal tract
The study suggests that improved testing vaccination of cattle and culling all cattle on infected farms would be the most effective strategies for controlling the disease.

which in the longer term may allow us to develop vaccines says Wigley. Story Source:
Although medicine and vaccines can prevent some diseases they don't prevent them all in those cases stopping the bite in the first place is the best line of defense.
and no vaccine against the disease repellents are the number one protection. It is winter in Brazil at the moment
Vaccines and treatments are available for some diseases but not all and so the best way to keep as safe as possible is to use an insect repellent containing DEET and reapply it regularly.
This form of milk vaccination might serve as a basis for developing an immunisation strategy to prevent swine coccidiosis.
Mannose receptorright now there are no effective vaccines or treatments to combat infections of this type so innate immunity factors are being studied as an effective alternative to treat
Importantly our study also revealed that the undesirable side effect of this vaccination a reduction in growth can be uncoupled from the beneficial immune reaction Dr Berkowitz said.
#First metritis vaccine protects dairy cowscornell scientists have created the first vaccines that can prevent metritis one of the most common cattle diseases.
The new vaccines prevent metritis infection of the uterus from taking hold and reduce symptoms when it does a prospect that could save the United states billions of dollars a year
Three of the vaccines Bicalho's lab created lowered metritis incidence and lessened its symptoms in the cows that received them showing promise for alternatives to antibiotics in addressing the disease.
Our lab has been developing a vaccine for years now based on our research of this disease said Bicalho.
We created multivalent vaccines complex cocktails with several components we've identified as important to causing metritis.
All three subcutaneous vaccines were effective significantly reducing incidence of disease by up to 83 percent.
Cows that were vaccinated with the subcutaneous vaccines had lower incidence of postpartum fever and puerperal metritis shorter disease periods and improved reproductive performance compared to those that did not receive the vaccines.
The powerful protection these vaccines produced surprised us. We expected some protective effect but nothing as strong as what we found said Bicalho.
An effective vaccine against uterine diseases will have a significant positive impact on the dairy industry limiting the use of antibiotics and decreasing economic losses due to these disorders.
Our next step is to simplify the complex vaccines we created by identifying which components are the most important
and removing the rest. Story Source: The above story is provided based on materials by Cornell University.
Fortunately it is recognized increasingly that a combination of improved testing vaccination and standardized approaches to meat preparation can prevent spread of diseases without the need to separate cattle from wildlife by fencing.
#Studies of cow antibodies help scientists understand how our own bodies workunderstanding how antibodies work is important for designing new vaccines to fight infectious diseases
In addition to the obvious benefit of helping us understand the human immune system the research may benefit the large-scale raising of cattle an important segment of the U s. economy as new vaccines can be developed to protect farm animals from common cattle diseases.
and how it has jumped between different host species. The findings may have implications ranging from the assessment of health risks for populations to developing vaccines.
This finding suggests that ECP could be considered as a potential antigen for vaccines for both human and poultry infections.

Malaria vaccine from the teats of genetically altered goatsmost malaria vaccines require multi million dollar facilities for production.
Co. Exist reports that Texas A&m researchers have engineered goats that can produce a malaria vaccine in their milk.
These genetically modified animals lactate the vaccine proteins. At this point the milk has to be treated to isolate the vaccine for injection,
but the scientists hope to have drinkable milk vaccines within the next decade. Head researcher Mark Westhusin tells Co. Exist's Ben Schiller:
There is tremendous potential to produce malaria vaccines and other types of medicines, especially for Third world countries.
If you produce these proteins in goats and other transgenic animals, it s way more efficient,
The World health organization quickly launched a full effort toward creating a vaccine for this new strain.
