#Researcher develops vaccine for fatal disease Over 200 million people in 74 countries suffer from schistosomiasis
Afzal A. Siddiqui, Ph d.,has tested his new vaccine in animals and is now planning human trials.

An effective vaccine is critical toward providing long-term treatment. This schistosomiasis vaccine offers unique opportunities for organizations to market it as a method for completely eliminating this disease.
The vaccine's advantages make it easy to sell because it eliminates the instances of re-infection common with the current chemotherapeutic drug,
is easier and less expensive to distribute and can be administered with current chemotherapy regimen. Long-term vaccine efficacy will effectively reduce the transmission of schistosomiasis in endemic areas.
According to the World health organization there are no commercially available vaccines against schistosomiasis, which afflicts people in countries primarily in Asia, Africa and South america.
Symptomatic schistosomiasis can result in increased susceptibility to sexually transmitted infections including HIV, which is prevalent in many countries plagued by schistosomiasis.

"Cancer vaccines are designed to turn a patient's own immune system more strongly against cancer cells, and have been an area of recent and intense interest among oncologists.
Since 2010, the FDA has approved vaccines and other immunotherapy drugs for melanoma, prostate cancer, and lung cancer.
There are currently dozens of active clinical trials evaluating vaccines for cancer therapy. Approximately 235,000 new diagnoses of breast cancer were made last year,
As yet, there are no FDA-approved vaccines for breast cancer. Such a vaccine might target HER2 a cell surface hormone receptor that is overexpressed in the tumor cells of 15 to 30 percent of breast cancer patients.
Such cells are called HER2+or HER2 positive. In this case, HER2 is both a naturally occurring hormone receptor and an antigen target for therapy.
A vaccine against HER2 would train the immune system's more destructive agents to recognize the cancer cells overproducing HER2
But so far, vaccines against HER2 have seen only moderate success."Vaccines targeting the HER2 oncoprotein have been tried,

Unfortunately several studies have shown that the two available living vaccines Rotarix and Rotateq which are recommended by bodies including the World health organization are not sufficiently effective in developing countries.
%The current study to be published in the Journal of Clinical Infectious diseases by Johan Nordgren from Professor Lennart Svensson's research group shows that up to four of ten children in Burkina faso are genetically resistant to the virus strains found in the vaccines.
The researchers found that children who can not express a particular sugar molecule in the small intestine called the Lewis molecule do not become infected by the rotavirus types found in existing vaccines.
This means that these children do not get the desired immunological protection from the vaccine.
and can greatly impact the evaluation of the rotavirus vaccines now being introduced in several developing countries.
The results could lead to a review of the vaccine composition and the development of vaccines better suited to the populations most affected by rotavirus.
