Meet the man behind a new HIV vaccine that could help end the virus for good.

Dr. Robert Gallo has spent decades aiming to end AIDS.

If there ever were a pioneer in the war on AIDS, Dr. Robert Gallo would certainly fit the bill.

That may seem like common knowledge today. But back in the 1980s — when the AIDS crisis was ravaging communities across the U.S. and very little was known about the virus — it was nothing short of groundbreaking.

He then spearheaded a blood test that can detect the virus in humans.

The blood test has had big ramifications in curbing HIV infections, as health care workers became equipped to rapidly diagnose infected patients.

And on Oct. 8, 2015, Gallo was at it again, announcing yet another big step in the fight against HIV: His potentially game-changing vaccine is going to human trial.

Sure, there are other HIV-fighting vaccines in human trial (about 30, in fact). But Gallo's vaccine, which has taken his team at the University of Maryland's Institute of Human Virology nearly two decades to produce, stands out ... in a good way.

There are many strains of HIV that can affect the immune system. And that makes creating a universal vaccine that stops all of them a bit tricky. If proven successful, however, Gallo's vaccine would protect patients' immune systems from the variations of the virus classified under "HIV-1," which constitutes the vast majority of infections worldwide.

"Our HIV/AIDS vaccine candidate is designed to bind to the virus at the moment of infection, when many different strains of HIV found around the world can be neutralized. We believe this mechanism is a major prerequisite for an effective HIV preventive vaccine." — Dr. Gallo

Enrollment in the trial opened this month, and the institute is looking for 60 people to participate in its year-long phase 1, according to The Baltimore Sun.

It's a promising step forward in the fight against a virus that's had a massive impact on global health.

There are about 35 million people living with HIV/AIDS around the world, according to the World Health Organization. About 1.5 million people died from the virus in 2013 alone. Sub-Saharan Africa — where nearly 71% of people living with HIV globally reside — has been affected far more than other regions of the world.

Although new medicines have helped HIV patients live longer, healthier lives, there is still no cure for the virus. And even for those fortunate enough to be living in regions with access to such medicines, drugs can be expensive (although that doesn't stop some greedy pharmaceutical company CEOs from inflating prices even further ... yeah, I'm talking about you, Martin Shkreli).

Gallo's vaccine could be huge. But even if it turns out to be, there are plenty of hurdles before patients can benefit.

Gallo's announcement is exciting! But let's not put the cart before the horse. Before the vaccine gets clearance from the FDA and becomes a welcomed reality for patients, it has to successfully pass a range of human trials. And that will take several years to complete.

But Gallo is confident the long road ahead will bring promising results.

"Can I promise absolute success? No," Gallo said of the vaccine's potential, according to The Baltimore Sun. "Do I hope it leads to a series of advances in the fields? Yes. And I think it will lead to some advances."
