A new Zika virus vaccine has been developed that works on animals, providing hope for providing a human protection jab soon. The vaccine has had 100% success in blocking Zika and virus related side effects in lab mice.
The trial team in the USA has produced a single jab consisting of an inactivated and purified form of Zika virus, that gives mice total protection against this fast-spreading disease that has swept through countries such as Brazil and other areas of South America. Showing no signs of slowing down, this mosquito-carried disease is spreading globally and the race is on to convert this successful animal vaccine into an effective human immunisation.
Since the World Health Organisation declared the Zika virus a global epidemic and worldwide public health emergency in February, clinical trials into creating an effective human vaccine have been considered top priority. Mosquitoes in over 60 countries are now believed to carry the virus that causes paralysing neurological disorders and severe birth defects – http://www.bbc.co.uk/news/health-36645822.
Trials are underway, but there are concerns, due to its similarity to other vaccines in circulation, that the jab may be less effective in certain people, and could also have the potential to make other infections, for example dengue fever, more dangerous. This is of particular concern as dengue viruses circulate in the same global areas as Zika, and protecting against Zika while making another viral infection worse, could be potentially life-threatening in some cases.
Clinical trials for Zika must have adequate funding and expertise to make them viable studies. Clinical staffing solutions can be arranged through companies such as http://www.gandlscientific.com/clinical-staffing-solutions. Effective results will only be gleaned from quality controlled trials run by experienced and professional personnel.
It takes years of testing for a vaccine to become licensed and available to the general public. If human testing goes well, we could see a vaccine developed in the coming years that will successfully protect those most as risk, including pregnant women. The cases of microcephaly in newborn babies in Brazil has reached epidemic levels, linked to the Zika virus, it is the birth defect of babies being born with abnormally small heads. This devastating disease compounds the speed at which we need a successful and fully tested human vaccine to become globally available.
