World’s news are reporting that scientists in Quebec will test the controversial zika vaccines on healthy volunteers. The government and US Food and Drug Association support this action.
Are zika vaccines safe?
What we all know is that zika virus is transmitted by mosquitoes and provokes birth defects among babies. This vaccine is designed exactly for that reason. It need to reduce or completely stop the spreading of the virus. But, it still need to be tested in order to see its effects.
For that reason, more than 50 volunteers from different cities are gathered.
Health researchers prefer these zika vaccines because they are believed to be more sable. Furthermore, they have reduced risk of accidental infection by the pathogen. On the other hand, scientists have investigated these DNA vaccines in the early 1990s. DNA vaccines are responding to viral and non-viral antigens.
However, the positive effect of these vaccines was never proved. Doctors are saying that these vaccines have many side effects. They can provoke mutations that are occurring due to a new genetic material inserted into a normal gene.
According to the researchers, this action is very dangerous. They can increase the risk of cancer among volunteers. So, that is why they need to be tested very rigorously.
One of the greatest concerns of the scientists are the vaccine effects on the immune system. If something goes wrong, these people will suffer until the end of their life. Their immune system will be weak which will make them less resistant to diseases. However, despite the risks, they are determined to completely cure the zika virus. They will compare the immune results from the volunteers and the immune results from the animals. According to the scientists and the vaccine manufacturers, the second test phase will include larger group of volunteers.
One question remains unanswered. Is it worth the risk that these volunteers are taking?
