HIV is a virus that weakens a person’s immune system. If the immune system is weak, it can’t defend against diseases — making something as simple as a cold life-threatening. Did you know that about half of the people living with HIV are not getting the treatment they need? As a result, millions of people die from HIV worldwide every year. But what if we provided HIV treatment to more people? What if people could get vaccinated? Researchers are developing a vaccine that can stop people from getting infected with HIV in the first place. In this study, we found that providing treatment to more people living with HIV will save a lot of lives. However, if we also gave people a vaccine that protects them from getting HIV, we could lead the world towards getting rid of HIV forever.
