The only thing Brazil should fear more than the genetically modified Zika mosquitoes is the vaccine antidote if the experimental Ebola vaccines are anything to go by.

Yet plans are already underway to give the population of Brazil, and others, a Zika vaccine, according to media reports.


One experimental Zika vaccine is being developed in a cooperation between the Brazilian Ministry of Health, the Evandro Chagas Institute and a USA medical university,  University of Texas Medical Branch in Galveston (UTMB), with houses one of the country’s foremost biological weapons labs.

“The Galveston National Laboratory (GNL) in Galveston, Texas, USA, is a high security National Biocontainment Laboratory housing several Biosafety level 4 research laboratories, run by the University of Texas Medical Branch for exotic disease diagnosis and research,” according to Wikipedia.

Pei-Yong Shi from UTMB said the plan was to find a vaccine for Brazil “that can be effectively mobilized to immunize the population and is a very strong vaccincation.”

Numerous other biotech and pharmaceutical companies currently joining the race to produce experimental Zika vaccines, including Sanofi and GlaxoSmithKline.


The problem from the point of view of public health is that vaccines  issued under a WHO public health emergency declaration do not need to meet even minimal standards of safety or efficacy.

A disclaimer on WHO’s “Emergency Use Assessment and Listing Procedure (EUAL)
for candidate vaccines for use in the context of a public health emergency” makes this clear.

“WHO explicitly disclaims any warranty of the fitness of any listed
investigational vaccines for a particular purpose, including in regard to its safety
and/or efficacy,” says the document.

“WHO disclaims any and all liability and responsibility for any injury, death, loss,
damage or other prejudice of any kind whatsoever that may arise as a result of or in
connection with the procurement, distribution and use of any investigational
product included in the list.”


The justification WHO uses for rolling out risky experimental Zika vaccines is supposed to be that Zika causes microcephaly and the Guillane Barre Syndrone.

But there is no evidence that Zika virus cause microcephaly or the Guillaine Barre Syndrone.

Peadiatric cardiologist Dr. Sandra Mattos showed that cases of microcephaly had been under reported for years before the Zika outbreak.


A study “Update on Zika virus transmission in the Pacific islands, 2007 to February 2016 and failure of acute flaccid paralysis surveillance to signal Zika emergence in this setting” has revealed no link between Zika and the Guillaine Barre Syndrone.


The experimental Zika vaccine could be worse than the  rather mild disease transmitted genetically modified Zika mosquitoes, produced and released into the wild by a British biotech company called Oxitec.

These genetically modified mosquitoes depend upon the antibiotic tetracycline to survive and to create offspring.

“Its mosquitoes aren’t sterile; instead, they’re engineered to vastly overproduce a protein that kills them unless they are fed the antibiotic tetracycline, as they are in the production center. Without the antidote, the released males quickly die off, as do their offspring.


The offspring are supposed to quickly die in the wild without this antibiotic, long before they can become adults.

But the antibiotic tetracycline they depend on to survive is virtually omnipresent in the environment. Its hdrophilic properties mean the antibiotic is especially concentrated in water, the breeding sites of mosquitoes.

“Due to their extensive usage, most of the actual evidence suggests that tetracycline antibiotics are omnipresent compounds found in different ecological compartments. After medication, more than 70 % of tetracycline antibiotics are excreted and released in active form into the environment via urine and feces from humans and animals. Their highly hydrophilic character and low volatility have resulted in significant persistence in the aquatic environment.”


That means that the offspring of the GM mosquito are likely survive and live long enough to feed off humans, spread the Zika virus and reproduce and mutate.

The GM mosquitoes were released close to the Zika outbreak began in Brazil. The Zika mosquisto is also characterized by the unusual speed with which it spreads.

The same GM mosquitoes have also been released in the Cayman Islands and Panama and Malaysia, and there has been a  sudden surge in Zika there too.

But the disease they spread seems to be relatively mild. Such a mild disease does not justify the dangerous experimental of mass vaccination with experimental Zika vaccines.
