As the FDA prepares to take a more active role in the oversight of genetic tests, the agency is finding itself in unfamiliar territory: regulating software.

 

In the past, reviewing new diagnostics rarely involved stepping far outside the wet lab. Tests might involve finding a pathogen under the microscope, or detecting an analyte through a chemical reaction in a test tube: simple yes or no questions that just had to be checked to make sure they reliably gave the right answers.

 

GENEVA— The World Health Organization and Tanzanian Ministry of Health are stepping up efforts to contain and discover the source of a cholera epidemic that so far has killed eight people and infected more than 400 others.

 

WHO data indicates the fast-spreading epidemic broke out in the Dar es Salaam and Morogoro regions nearly two weeks ago; the Dar es Salaam region has been most adversely affected with 354 cases and seven deaths.

 

WHO spokesman Christian Lindmeier tells VOA the outbreak caught health officials by surprise.

PESHAWAR / DI KHAN, PAKISTAN: 

Around 1.7 million children will be administered measles and polio vaccines in the Federally Administered Tribal Areas during an ongoing immunisation drive.

 

When it comes to a vaccine to prevent cholera, one dose may be as good as two. That is the finding of a new study whose authors say the strategy would make a new vaccine that is in short supply go further.

 

The World Health Organization is stockpiling 2 million doses of a recently licensed oral cholera vaccine to prevent the severe diarrheal illness.  

 

An estimated 1.4 billion people around the world, according to the WHO, are at risk for contracting the water-borne illness, making the stockpile woefully inadequate to meet the need.

The NIAID may have posted 94% efficacy in mice for its investigational "universal" flu vaccine, but The Scripps Research Institute and partner Johnson & Johnson ($JNJ) are hot on its heels. Scripps announced Monday that its most advanced candidate fully protected mice in a lethal challenge. They also conducted a sublethal challenge, where the vaccine reduced fever in monkeys.

 

When you mention innovation, most people immediately think of the latest app that tracks daily life with pinpoint precision, or costly new technologies like Google Glass that just a decade ago would have been considered impossible.

 

Vaccination campaigns that use a single dose of oral cholera vaccine (OCV) may be able to prevent more deaths than the standard two-dose campaign, according to a modeling study published online August 25 in PLOS Medicine. Such a strategy may be especially important when vaccine supplies are limited or when an outbreak is characterized by complex logistics.

 

Scientists at the University of Pennsylvania have developed a DNA vaccine that can protect against the Middle East Respiratory Syndrome (MERS). This is the first synthetic vaccine that has been shown to induce protective immunity against the virus in animals, the researchers say.
