Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. The severity of the condition is variable.
Streptococcus pneumoniae, or pneumococcus, is a Gram-positive, spherical bacteria, alpha-hemolytic member of the genus Streptococcus. They are usually found in pairs (diplococci) and do not form spores and are non motile. As a significant human pathogenic bacterium S. pneumoniae was recognized as a major cause of pneumonia in the late 19th century, and is the subject of many humoral immunity studies.
Pneumococcal polysaccharide vaccine (PPSV)—known as Pneumovax 23 (PPV-23)—is the first pneumococcal vaccine derived from a capsular polysaccharide.
Meningococcal disease describes infections caused by the bacterium Neisseria meningitidis. It has a high mortality rate if untreated but is vaccine-preventable. While best known as a cause of meningitis, it can also result in sepsis, which is an even more damaging and dangerous condition. Meningitis and meningococcemia are major causes of illness, death, and disability in both developed and under-developed countries.
Pneumococcal conjugate vaccine is a pneumococcal vaccine and a conjugate vaccine used to protect infants, young children, and adults against disease caused by the bacterium Streptococcus pneumoniae (pneumococcus). It contains purified capsular polysaccharide of pneumococcal serotypes conjugated to a carrier protein to improve antibody response compared to the pneumococcal polysaccharide vaccine. The World Health Organization (WHO) recommends the use of the conjugate vaccine in routine immunizations given to children.
Pneumococcal vaccines are vaccines against the bacterium Streptococcus pneumoniae. Their use can prevent some cases of pneumonia, meningitis, and sepsis. There are two types of pneumococcal vaccines: conjugate vaccines and polysaccharide vaccines. They are given by injection either into a muscle or just under the skin.
A pneumococcal infection is an infection caused by the bacterium Streptococcus pneumoniae, which is also called the pneumococcus. S. pneumoniae is a common member of the bacterial flora colonizing the nose and throat of 5–10% of healthy adults and 20–40% of healthy children. However, it is also a cause of significant disease, being a leading cause of pneumonia, bacterial meningitis, and sepsis. The World Health Organization estimates that in 2005 pneumococcal infections were responsible for the death of 1.6 million children worldwide.
Meningitis is acute or chronic inflammation of the protective membranes covering the brain and spinal cord, collectively called the meninges. The most common symptoms are fever, headache, and neck stiffness. Other symptoms include confusion or altered consciousness, nausea, vomiting, and an inability to tolerate light or loud noises. Young children often exhibit only nonspecific symptoms, such as irritability, drowsiness, or poor feeding. A non-blanching rash may also be present.

She is especially recognized for her work with new vaccine introduction, which has included strategies to accelerate access in low and middle-income countries, policy research, advocacy, communications and large country introduction.
Orin Levine is an epidemiologist known for his work in the fields of international public health, child survival, and pneumonia. He is currently the director of vaccine delivery at the Bill & Melinda Gates Foundation in Seattle, US. In the past he was the executive director of the International Vaccine Access Center (IVAC), the co-chair of the Pneumococcal Awareness Council of Experts (PACE), and is a professor at The Johns Hopkins Bloomberg School of Public Health in the Department of International Health. He is also an adjunct assistant professor of epidemiology at The Rollins School of Public Health at Emory University in Atlanta. Additionally, he is currently president of the American Society of Tropical Medicine and Hygiene (ASTMH) Council on Global Health. He resides in Washington, D.C.
World Pneumonia Day provides an annual forum for the world in the fight against pneumonia. More than 100 organizations representing the interests of children joined forces as the Global Coalition against Child Pneumonia to hold the first World Pneumonia Day on 12 November 2009. Save The Children artist ambassadors Gwyneth Paltrow and Hugh Laurie, Charles MacCormack of Save The Children, Orin Levine of PneumoADIP, Lance Laifer of Hedge Funds vs. Malaria & Pneumonia, the Global Health Council, the GAVI Alliance, and the Sabin Vaccine Institute joined together in a call to action asking people to participate in World Pneumonia Day on 2 November.
Katherine "Kate" L. O'Brien is a Canadian American pediatric infectious disease physician, epidemiologist, and vaccinologist who specializes in the areas of pneumococcal epidemiology, pneumococcal vaccine trials and impact studies, and surveillance for pneumococcal disease. She is also known as an expert in infectious diseases in American Indian populations. O’Brien is currently the Director of the World Health Organization's Department of Immunization, Vaccines and Biologicals.
The African meningitis belt is a region in sub-Saharan Africa where the rate of incidence of meningitis is very high. It extends from Senegal to Ethiopia, and the primary cause of meningitis in the belt is Neisseria meningitidis.
The Global Coalition Against Child Pneumonia exists to raise global awareness about the deadly toll of the number 1 killer of children - pneumonia. Every year 155 million children under 5 get sick and 1.6 million lose their lives to pneumonia, more than all child deaths combined from AIDS, malaria and measles. Almost all of these child deaths occur in developing countries with most concentrated in just seven - India, China, Democratic Republic of Congo, Ethiopia, Nigeria, Pakistan and Afghanistan.
Universal Immunisation Programme (UIP) is a vaccination programme launched by the Government of India in 1985. It became a part of Child Survival and Safe Motherhood Programme in 1992 and is currently one of the key areas under the National Health Mission since 2005. The programme now consists of vaccination for 12 diseases- tuberculosis, diphtheria, pertussis, tetanus, poliomyelitis, measles, hepatitis B, rotaviral gastroenteritis, Japanese encephalitis, rubella, pneumonia and Pneumococcal diseases. Hepatitis B and Pneumococcal diseases were added to the UIP in 2007 and 2017 respectively. The cost of all the vaccines are borne entirely by the Government of India and is funded through taxes with a budget of ₹7,234 crore (US$910 million) in 2022 and the program covers all residents of India, including foreign residents.
GAVI, officially Gavi, the Vaccine Alliance is a public–private global health partnership with the goal of increasing access to immunization in poor countries. In 2016, Gavi channeled more than half of total donor assistance for health, and most donor assistance for immunization, by monetary measure.
George Rainer Siber is a medical researcher and vaccine expert with 48 years of experience in developing numerous vaccines, therapeutic antibodies, and diagnostic agents for infectious diseases.
Claire Veronica Broome is an American epidemiologist, specializing in public health surveillance and vaccine evaluation, who has contributed to the development and effective utilization of key vaccines against pathogens causing pneumonia and meningitis.
Samir Kumar Saha is an eminent Bangladeshi microbiologist and public health expert.
