Researchers Offer Strange Answer to Anticipated Dengue Spikes Following Vaccine

Heather Callaghan

Researchers indeed continue to develop vaccines for tropical, mosquito-vectored diseases like dengue fever, which affects 50 million people per year. 

There are no commercially available vaccines for the virus - yet. But, they've run into a big problem.

Researchers watching vaccine development caution that there will be initial disease spikes with its use. There's no argument about this observation. In fact, it's admitted. 

But the explanation to ward off panic and ensure that people in other countries will take that future risk, is beyond a mental back flip.

Whooping Cough Rapid Rise After 20-Year Use of Poor Quality Vaccines

The rate of whooping cough, or pertussis, has exploded in America in the last few years. A brand new study confirms what scientists already expected. They confirmed that the burgeoning comeback of whooping cough is due to introducing new, "safer" vaccines 20 years ago. Safer, meaning fewer side effects and minus the previous toxin that was used, but not safe for long-term protection from disease.

Pertussis bacteria affects upper respiration and creates shortness of breath. The disease, which can be fatal to babies, actually almost disappeared in the late '70s - so why did newer vaccines keep appearing? It seems to have caused a type of resistance. The weaker vaccine has caused damage; arguably more than foregoing the vaccine altogether.

By the '80s it was believed to be more hushed, spreading undiagnosed. In 20 years, however, it has "bounced back with a vengeance." Europe is seeing the same problem. Last year in the U.S., there were 40,000 cases, and strong strains among kids in 2010. California, for instance, saw an epidemicof it in 2010, especially among their Latino community - the situation was rife with calls for mandatory vaccination - for the very vaccine that could be spiking the disease.
