Scientists have always been working on finding a safe and effective HIV vaccine. While so many advancements have been made over the past 4 decades since HIV was first discovered, inventing an HIV vaccine proves to be daunting and challenging. In March 2022, NIAID in collaboration with Moderna conducted a clinical trial of 3 experimental HIV vaccines utilizing the messenger RNA technology, a technology used in the discovery of the first two licensed COVID-19 vaccines. These vaccines work by triggering the body’s immune response to a certain pathogen.

STDs can increase the risk of HIV transmission. Several STDs changes the cell lining in the vagina, penis, mouth or rectum and cause lesions on the skin or organ surfaces that facilitate HIV transmission. The other way this can happen is when immune cells are trying to fight inflammation caused by existing STDs and HIV tries to infect these immune cells. In this article, we discuss which particular STDs increases the chances of you getting infected with HIV why it happens

HPV is indeed one of the most common sexually transmitted infections. While HPV types 16 and 18 are hazardous and can lead to cervical cancer, strains 6 and 11 can develop into an uncomfortable health condition called genital warts.
