By immunizing children against pneumococcus in the world’s poorest countries, we can save the lives of millions of children.

our goal:

to significantly reduce childhood deaths from pneumonia.

The Challenge

At A Glance

Pneumonia is the leading cause of death among children under age 5, with more than 99 percent of those deaths occurring in the developing world.

Childhood deaths from pneumonia are preventable using existing vaccines, diagnostic tools, and treatments.

We work to improve the development and delivery of pneumonia vaccines and expand the use of antibiotic treatments and diagnostic tools.

We support the goals of the Global Action Plan for Prevention and Control of Pneumonia (GAPP), an effort led by the World Health Organization and UNICEF to accelerate pneumonia prevention and control.

Our Pneumonia strategy is led by Trevor Mundel, president of the foundation’s Global Health Division.

Even as global child deaths have declined from 12 million to 6.9 million over the last two decades, pneumonia has remained the world’s leading cause of death among children under age 5. Despite available interventions, pneumonia claimed the lives of 1.3 million children in 2011 and was responsible for 18 percent of child deaths worldwide—nearly all of them in developing countries, particularly in Sub-Saharan Africa and South Asia.

Because pneumonia can be caused by a number of viruses and bacteria, a range of interventions are needed to reduce childhood mortality from the disease. The most common causes are the Streptococcus pneumoniae (pneumococcus) and Haemophilus influenzae type b (Hib) bacteria and respiratory syncytial virus (RSV).

Childhood deaths from pneumonia are preventable using existing vaccines, diagnostic tools, and treatments, but issues of availability, access, and cost remain obstacles in the developing world. Nearly half of early childhood deaths from pneumonia are estimated to result from lack of diagnosis or treatment or delayed diagnosis and treatment. In resource-limited settings, factors such as malnutrition, HIV infection, and indoor air pollution increase children’s risk of developing pneumonia.

The Opportunity

The global health community has adequate tools and is developing better ones to significantly protect children from pneumonia in the developing world.

Vaccines have already helped to substantially reduce childhood pneumonia. But vaccine coverage must be improved, and lower-cost vaccines are needed where the burden of pneumonia is highest, particularly in India. Early treatment is also critical. If properly diagnosed, childhood pneumonia can be effectively treated with a three-day course of antibiotics at a cost of only 21 to 42 U.S. cents.

Fortunately, awareness of pneumonia as a major global health problem has increased. In 2009, the World Health Organization (WHO) and UNICEF launched the Global Action Plan for Prevention and Control of Pneumonia (GAPP) to fight the disease. The GAPP calls for the aggressive use of proven interventions, including vaccination against measles, pertussis, pneumococcus, and Hib; exclusive breastfeeding in the first six months of life; and improved case management in communities.

Our Strategy

The Bill & Melinda Gates Foundation’s pneumonia strategy broadly reflects the Protect, Prevent, Treat framework used by the GAPP. We focus on the most prevalent causes of childhood pneumonia—pneumococcus, influenza, and RSV—and we are continuing our longstanding investment in vaccines against meningococcus, which causes epidemic meningitis, even though it is not a major cause of pneumonia.

Our key partner in increasing access to pneumococcal vaccines is the GAVI Alliance, a public-private partnership that funds vaccines for children in the world’s poorest countries. By immunizing children against Hib and pneumococcus in these countries, we can save the lives of 2.9 million children and prevent 52 million cases of pneumonia.

Our top priority is to promote full-scale delivery of currently available pneumococcal and meningococcal vaccines and to support the development of new vaccines to improve coverage, efficacy, safety, and cost effectiveness.

Because vaccines cannot prevent all cases of pneumonia, we also work to improve access to treatment options in public and private healthcare systems. Saving lives through improved access to treatment is particularly critical in countries where the introduction of vaccines is lagging.

Other priorities include improving the quality of pneumonia-related data collection, increasing international funding, evaluating the benefits of maternal immunization to protect women and their babies from influenza and RSV, and researching the links between pneumonia and indoor air pollution.

Our strategy complements efforts by several other foundation programs, including those for vaccine delivery; nutrition; maternal, neonatal, and child health; and enteric and diarrheal diseases. By immunizing children against Hib and pneumococcus in these countries, we can save the lives of 2.9 million children and prevent 52 million cases of pneumonia.

Areas of Focus

Our work focuses on seven priority initiatives: pneumococcus, meningococcus, diagnosis and treatment, strategic information and advocacy, RSV, influenza, and risk factors. While pneumonia affects people of all ages, our priority is children under age 5.

Pneumococcus

Pneumococcus is the leading cause of pneumonia and is responsible for 40 percent of cases in children under age 5. We work to broaden access to the two commercially available pneumococcal conjugate vaccines (PCVs) while also investing in the development, regulatory approval, and deployment of newer and improved vaccines.

We have worked with the GAVI Alliance to implement the Advance Market Commitment for Pneumococcal Vaccines, an innovative financing mechanism that accelerates late-stage development and manufacturing of pneumococcal vaccines for developing countries.

The price of PCVs is relatively high compared to other vaccines in routine immunization programs in most countries. We address this challenge by supporting efforts to broaden the supplier base to reduce prices and by working with PATH and the Serum Institute of India to develop a low-cost PCV for India and other countries with a high burden of pneumonia.

Meningococcus

In an effort to eliminate epidemic meningitis A in Africa, we support the Meningitis Vaccine Project, a collaboration that also includes PATH, WHO, African health ministers, and the Serum Institute of India. The project has developed an affordable vaccine called MenAfriVac—the first vaccine developed specifically for Africa—that provides lasting protection from life-threatening meningococcal meningitis, a bacterial infection of the fluid surrounding the brain and spinal cord.

MenAfriVac was first introduced in Burkina Faso in 2010. Since then, more than 100 million people have received the vaccine, and it continues to be introduced throughout the “meningitis belt” in Sub-Saharan Africa. Our current investments will enable the use of MenAfriVac in infants and promote its inclusion in routine immunization programs in all countries in the meningitis belt.

Initial data suggests that MenAfriVac is effective in reducing meningococcal A outbreaks; the meningitis A bacterium has been nearly eliminated in vaccinated populations so far. We support continued studies and surveillance to monitor the evolution of the disease and the potential need for meningitis interventions beyond this new vaccine.

Diagnosis and Treatment

Urgent work is needed to ensure that children who are sick with a severe respiratory illness receive appropriate care. Many children die because their families do not recognize the symptoms or are unable to quickly get them to a healthcare provider. Children who do reach a provider might be misdiagnosed or not given the correct antibiotic therapy. If the illness has progressed to a level of severity that requires highly technical skills or equipment, those resources might not be available or accessible.

We work closely with other teams at the foundation to improve access to effective treatment for sick children, with a special focus on Nigeria, northern India, and Burkina Faso. Our decision to focus on these countries is based on the burden of childhood illness, readiness to innovate, and strong partner organizations. Our work includes educating caregivers on the signs and symptoms of pneumonia and increasing women’s autonomy to seek and advocate for care. We also invest in the development of tools to diagnose pneumonia quickly and to improve triage and referral systems for very sick children.

In countries where the Community Case Management approach is being used to train community members to deliver interventions for common childhood illnesses, we work to make such efforts more sustainable. We also work to improve the quality of care delivered by small-scale private providers, who are often the nearest healthcare option for many families in poor countries.

Strategic Information and Advocacy

We invest in the collection and use of high-quality data on the causes and global burden of pneumonia, which will contribute directly to vaccine development, better treatments, improved service delivery, innovation in diagnostics and treatment, and better reporting on causes of death.

We also work to raise the profile of pneumonia as a critical child health issue. Our priorities include ensuring sufficient funding for critical vaccines; supporting vaccine and child health advocates; and building political will at the global and country levels for evidence-based pneumonia prevention and treatment. We also seek to increase resources dedicated to immunization programs and to ensure government follow-through on important global health initiatives such as the Global Vaccine Action Plan for the Decade of Vaccines.

Respiratory Syncytial Virus

RSV is one of the most common causes of childhood lung infections, mainly in the first six months of life. We support the development of maternal and infant RSV vaccines. We also work to improve global data collection on mortality and morbidity related to RSV and on the long-term consequences of severe RSV infections. This information will help in evaluating the potential impact and cost effectiveness of RSV vaccines that are under development, as well as alternative prevention strategies.

Influenza

We aim to address gaps in data on influenza in tropical and developing regions, assess existing strategies to stimulate demand for seasonal influenza vaccines, and ensure that pregnant women and young children in resource-limited settings can access affordable, effective vaccines.

Maternal influenza immunization has long been practiced safely in industrialized countries and could play an important role in reducing the burden of seasonal influenza in tropical regions by protecting pregnant women and the babies they carry.

Existing influenza vaccines are the basis of our maternal immunization strategy, which may pave the way for additional vaccines for pregnant women. We work with global partners to identify and address scientific, technical, regulatory, operational, and financial challenges to broadening maternal immunization efforts. We also support research to understand the benefits of maternal influenza immunization on fetal development and protection against illness.

In addition, we invest in the development of new and improved influenza vaccines for children under age 2.

Risk Factors

Along with our efforts to broaden immunization against pneumonia and improve treatment, we work to reduce environmental risk factors. Adequate nutrition and breastfeeding—addressed as part of the foundation’s nutrition strategy—are key factors in ensuring that children’s immune systems are equipped to fight off infection.

Reducing indoor air pollution is also likely to lessen the risk of pneumonia. We invest in limited research to fill fundamental gaps in knowledge about the dose-response relationship between indoor air pollution and childhood pneumonia. We also support efforts to improve monitoring technology to measure personal particulate matter and to establish surrogate endpoints for subsequent clinical trials. Our work in this area will evolve as our understanding of the link between indoor air pollution and pneumonia grows.
