Infectious diseases

Our focus has always been on the prevention and treatment of diseases that threaten people and communities around the world.

Our decades of research in infectious diseases have led to profound scientific advances

We’ve been working to combat global health threats caused by infectious diseases for more than a century, which includes pioneering research in HIV science, developing one of the first antibiotics and discovering and developing vaccines. But our work is far from done.

HIV

Our legacy in innovative HIV science continues

We remember when HIV was one of society’s most daunting challenges, when millions of people lost their lives to the devastating AIDS epidemic. Our scientists embarked on an urgent mission to unravel and understand the virus, which led to groundbreaking research in HIV. We are still driven to do more. We are pushing the boundaries of HIV science because unmet medical need still endures. Eradication of the virus is our ultimate goal.

Pneumococcal disease

Our decades-long dedication to pneumococcal disease prevention

Pneumococcal disease is an infection caused by a bacteria called Streptococcus pneumoniae. There are about 100 different types (referred to as serotypes) of pneumococcal bacteria, which can affect adults differently than children. Pneumococcal disease can lead to severe health issues, including pneumonia, sepsis and meningitis.

For over 40 years, our company has been dedicated to advancing research and innovation to help protect against this serious global public health threat.

Antibiotics

Collaborating to address antimicrobial resistance (AMR)

Our company has a strong legacy in antimicrobial R&D, with a broad portfolio that spans both human and animal health and includes antibiotics, vaccines and novel approaches to reduce the need for antibiotics. With the growing burden of antimicrobial resistance, we’re committed to dedicating our expertise and resources alongside our partners to support appropriate antibiotic use and encourage increased investment in future research.

We’re proud of our commitment to invest $100 million over 10 years in the AMR Action Fund. This groundbreaking partnership of over 20 leading pharmaceutical companies, philanthropies and organizations, aims to bring two to four novel antibiotics to patients and physicians by 2030.s.

Ebola Zaire

 Joining a partnership to combat a deadly virus

Since the emergence of the Ebola virus in 1976, periodic outbreaks have been a global health challenge. We are proud to be part of the global public-private partnership that has united government, industry, community groups, scientists, health care workers and ordinary people, to come together to help fight this deadly disease.

Dengue

Driving scientific discoveries to combat a mosquito-borne illness

With approximately half of the world’s population, or four billion people, at risk, dengue is a critical public health challenge. We’re working with urgency to advance research and innovation that aims to help protect the millions of people at risk for dengue infection.

COVID-19

Our response to COVID-19

Since the start of the pandemic, we’ve been focused on contributing our scientific expertise to help address COVID-19.
