New Japanese Encephalitis Vaccine Safe

RECENT studies say the type of vaccine for Japanese Encephalitis, a disease caused by viruses that evolved in Southeast Asia and parts of South Asia, proven safe and triggered a good immune response against pathogens. 

The disease is transmitted through mosquito bites, and can cause fever, headache, stiff neck, and convulsions, and for the five cases can be fatal. 

Tests of the vaccine is made by the Scottish subsidiary of Intercell AG, an Austrian head of the company, which has been tested on 867 adults in the United States, Britain, and Austria. 

According to research published in The Lancet, the response of the antibody to be doubled in the presence of a vaccine against the disease and very mild side effects. 

The U.S. Centers for Desease Control (CDC) says about 50,000 cases of Japanese encephalitis occur annually, particularly in children under 10 years old. 

This disease attacks in northern India this year attacked more than 300 inhabitants. Natural sources of this virus are pigs and wild birds. 

The vaccine is successfully recovered from the brains of mice that had been infected with the virus. The virus was then killed - disabled - using a chemical before it enters the body. 

The problem is, this vaccine is still expensive, difficult to produce, required three doses and is associated with allergic responses are bad, but this rarely happens. 

Some studies assert offsets or pig gelatin in rats on vaccine repair protein that causes all these responses. 

The researchers promised to investigate further about the risks and its use for children in areas that have been exposed to endemic. 

Alternatively, a vaccine made by China, which is based on virus growth in hamster cells, is also increasingly being used to fight the disease. 

Some countries in Asia already licensed the vaccine, including Nepal and India, who used it to vaccinate 30 million children in 2006 and 2007. Formula from China was only requires fewer doses, less expensive and seem to be more easily produced than a vaccine derived from mice.
