Current Status of HIV Preventive Vaccines: What You Need to Know - Internal Medicine

The current status of HIV preventive vaccines is a topic of great interest and importance, especially for individuals in relationships where one partner is HIV positive. As of now, there is no fully approved vaccine for the prevention of HIV infection. However, research is ongoing, and several candidates are in various stages of clinical trials. The goal of these vaccines is to stimulate the immune system to recognize and fight the virus if exposed, thereby reducing the risk of infection.

Currently, the most effective method for preventing HIV transmission remains the use of pre-exposure prophylaxis (PrEP). PrEP is a medication taken by HIV-negative individuals to reduce their risk of contracting HIV. When taken consistently, PrEP has been shown to be highly effective, reducing the risk of HIV infection by up to 99% during sex. It is important to note that PrEP does not protect against other sexually transmitted infections (STIs) or pregnancy, so additional protective measures may be necessary.

Regarding your question about whether there are any self-paid preventive vaccines available in your country, as of now, there are no licensed vaccines for HIV prevention that can be purchased. The research into HIV vaccines is promising, but it is still in the experimental phase. Therefore, relying on vaccines for protection is not currently an option.

In your situation, since your boyfriend is HIV positive, it is crucial to have open and honest discussions about your sexual health and the measures you can take to protect each other. Using condoms consistently and correctly is one of the best ways to reduce the risk of HIV transmission during sexual activity. Additionally, if your boyfriend is on antiretroviral therapy (ART) and has an undetectable viral load, the risk of transmission is significantly reduced. This concept is often summarized by the phrase "Undetectable = Untransmittable" (U=U).

If you are considering PrEP, it is essential to consult with a healthcare provider who can assess your risk factors and determine if PrEP is appropriate for you. PrEP requires a prescription and regular follow-up appointments to monitor kidney function and ensure that you remain HIV-negative.

In summary, while there is currently no preventive vaccine for HIV, PrEP is a highly effective method for reducing the risk of infection. It is essential to engage in safe sex practices, communicate openly with your partner about HIV status and prevention strategies, and consult with healthcare professionals to make informed decisions about your sexual health. Your proactive approach to understanding HIV prevention is commendable, and it is crucial to stay informed as research continues to evolve in this area.
