Researchers have been in overdrive to try and make a vaccinum that   might be capable to protect citizenry against the devastating Zika computer virus , as babies continue to be born with microcephaly and it continues to spread out around the reality . Hot on the hound of the tidings that one experimental vaccine has beengiven the greenish lightfor human trials , another two vaccine are now reported to provide   total protection against the virus in mouse .

This latest sketch , write inNature , has found that a single shot of the observational vaccines ease up sodding protection to animate being that   were then infected with Zika . The researcher tested   the vaccines against the virus strain found in Brazil , where the vast absolute majority of the cases have so far been reported , as well as   the strain found in Puerto Rico . However , there is still a farseeing way to go before human trials commence , as there are still massive unknowns as to how it will react in the human body .

It was onFebruary 1that the World Health Organization declared the eruption of Zika in the Americas as a public health emergency of outside concern , due to the striking spread of the disease throughout the part . In Brazil alone , it is thought thatat least 1.5 millionpeople have been infected , and   that it has spread to 39 countries since 2007 . It is now wide accepted that the disease causes microcephaly in babies , and there are potent hints that it can also do Guillain - Barré syndrome .

The paper actually count into two separate vaccine . “ One is a DNA vaccinum , the other is a purified inactivated virus vaccinum , ” said   Dan Barouch , who direct the study at the Beth Israel Deaconess Medical Center in Boston , at a Nature press briefing . “ These two candidate vaccines bring home the bacon full trade protection to Zika take exception mice . These determination for certain get up optimism that a secure and effective Zika vaccinum for human may be found . ”

One of the main question to do before any human trial run can start   is   how the vaccines interact with the dengue computer virus . Both dengue fever and Zika belong to the same family unit of virus , known as flavivirus , and both are beam by the sameAedes aegyptimosquitoes . There hasalready been some concernabout how the two viruses , and the antibodies that   they propel the organic structure to make , tie in to and touch on each other . There are some worry that the vaccines could be less in force when dengue is present , or that it could make infections from dengue unfit than normal .
