To mark World AIDS Day 2017, we have published a series of blog posts to highlight the important and varied research that takes places at Imperial. Three experts from Faculty of Medicine share their interest in HIV/AIDS which spans from the elusive vaccine to the economics of the epidemic.


World AIDS Day takes place annually on 1 December as an opportunity for people worldwide to unite in the fight against HIV and to show support for people living with HIV/AIDS.

The role of an economist in the HIV epidemic

As an economist, my research on HIV takes a higher-level population view. We advise policy makers in governments and international organisations on the cost-effectiveness of preventive and treatment interventions in the countries most ravaged by HIV. By estimating the benefits and costs of interventions, we can identify the ones that promise greatest improvements in population health. (more…)

World Polio Day: edging closer to eradication

As we mark the fifth annual World Polio Day, Dr Edward Parker talks about Imperial’s research supports the polio eradication initiative in a number of ways.


Imagine you are running a marathon. You have reached the final mile of a long and arduous journey. You turn the last corner expecting to see the finish line, and instead you see a huge vertical ascent. The finish line is waiting at the top, hundreds of metres above you.

Such is the plight of the Global Polio Eradication Initiative. In 1988, the year the initiative was launched, polio paralysed an estimated 350,000 people worldwide – roughly 1,000 each day. Over the last three decades, a globally coordinated vaccination campaign has fought the disease back to a few remaining refuges in Afghanistan, Pakistan, and Nigeria. In 2017, wild poliovirus has caused just 12 cases so far. (more…)

Today is World Rabies Day. Christl Donnelly explains why giving rabies vaccinations is the path to global eradication by 2030. 


The goal of this global day is enhanced awareness spurring further efforts to prevent rabies, a viral disease that kills tens of thousands of people each year mainly in Asia and Africa. Two years ago, international organisations – including the World Health Organization and the World Organization for Animal Health – agreed to an ambitious, but achievable common goal: to end human deaths due to canine rabies by 2030. In fact, ‘Rabies: Zero by 30’ is the theme of the 2017 World Rabies Day. (more…)
