AIDS is mainly caused by HIV infection, which is mainly preventive at present, but there is a lack of AIDS vaccine all over the world. No AIDS vaccine has been developed yet, so there is no specific date for the launch of the AIDS vaccine in China. There is still a need for further scientific research on the AIDS vaccine. If you are already engaged in high-risk behaviors, it is recommended that you go to the hospital in time and take oral antiviral blocking medication under the doctor’s supervision.
