"100% antibody production" can easily be interpreted as that the vaccine is effective against HIV 100%. But in fact, Zhang, a professor at Tsinghua University AIDS Comprehensive Research Center, explained: "After all vaccines are injected into the human body, antibody reactions will occur." In other words, "100% antibody production" does not directly prove that this vaccine can prevent AIDS. This means that antibodies that produce antibodies and antibodies that produce 100% immunity cannot be directly equated.

Wang Yuge is currently a postdoctoral fellow at Harvard Medical School in the United States. His research field is AIDS. He also holds the same view: "The vaccine has not been proved to be effective. The antibody produced by this vaccine is a normal reaction, but it cannot be said that protective antibodies have been produced. "

Figuratively speaking, antibodies are equivalent to the police in the body, and the principle of resistance is the bad guys who enter the body. Immune response is the process that the police set out to catch the bad guys, but the police may not catch the bad guys every time. Similarly, the report provided by Johnson & Johnson only mentioned that the experimental vaccine can stimulate the subjects to produce antibodies (police) and produce immune response (catching bad guys), but it has not been confirmed that antibodies can successfully neutralize HIV antigens (catching bad guys).

Experts said that at present, clinical trials are still in the early stage, and it is not rigorous enough to interpret the vaccine "100% antibody production" as "effective prevention" in the case of limited public data. It will take at least 5- 10 years to finally evaluate the effectiveness of this vaccine.
