In recent years, more and more people are suffering from AIDS, the age is smaller and smaller, until now appeared this kind of situation now, the number of young people with HIV/AIDS is rising, it has evolved into a subject groups, one for the curious: HIV/AIDS has already has more than 30 years, why haven’t developed the vaccine?
The answer is very frustrating
It is said that only one AIDS patient in the world has been cured, but this patient was also suffering from leukemia when he was suffering from AIDS. Finally, he was cured after bone marrow transplantation instead of drug treatment.
So AIDS is more than 30 years ago, why has not developed a vaccine?
Let’s take a look.
Although dozens of anti-HIV drugs have been successfully developed, turning AIDS from a “super cancer” to a chronic disease that can survive for a long time, more than 2 million people are infected and more than 1 million people die every year. The annual reported HIV/AIDS cases in China have increased from thousands in the early 21st century to more than 100,000 now.
But clinical trials still fail to produce a vaccine.
AIDS is a stubborn virus that lives in the human body.
You also know that HIV can be spread through sexual behavior and blood, it can be easily infected, once infected, so is the real tough, viruses can also directly into the body’s cells, damage the immune system, the destructive potential of this virus is too strong, at present many scientists are unable to find a breakthrough.
It is well known that the virus is gradually transmitted from chimpanzees, and few other animals are infected with HIV.
Therefore, the lack of animal models, also restricted the vaccine research, it can be said that the reality is very helpless!
