Streptococcus pneumoniae, or pneumococcus, is a Gram-positive, spherical bacteria, alpha-hemolytic member of the genus Streptococcus. S. pneumoniae cells 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.
Haemophilus influenzae is a Gram-negative, non-motile, coccobacillary, facultatively anaerobic, capnophilic pathogenic bacterium of the family Pasteurellaceae. The bacteria are mesophilic and grow best at temperatures between 35 and 37 °C.

Hattie Elizabeth Alexander was an American pediatrician and microbiologist. She earned her M.D. from Johns Hopkins University in 1930 and continued her research and medical career at Columbia-Presbyterian Hospital in New York City. Alexander became the lead microbiologist and the head of the bacterial infections program at Columbia-Presbyterian. She occupied many prestigious positions at Columbia University and was well honored even after her death from liver cancer in 1968. Alexander is known for her development of the first effective remedies for Haemophilus influenzae infection, as well as being one of the first scientists to identify and study antibiotic resistance. She has received many awards and honors including the E. Mead Johnson Award in 1942, for her headway in pediatric research and antibiotic resistance. Alexander's research and studies helped lay the ground work for research into antibiotic and vaccine development.
The Haemophilus influenzae type B vaccine, also known as Hib vaccine, is a vaccine used to prevent Haemophilus influenzae type b (Hib) infection. In countries that include it as a routine vaccine, rates of severe Hib infections have decreased more than 90%. It has therefore resulted in a decrease in the rate of meningitis, pneumonia, and epiglottitis.
John Bennett Robbins was a senior investigator at the National Institutes of Health (NIH), best known for his contribution to the development of the vaccine against bacterial meningitis Hib)) with his colleague Rachel Schneerson. He conducted research on the Bethesda, Maryland campus of the NIH from 1970 until his retirement at the age of 80 in 2012. During his tenure, he worked in the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) and the Food and Drug Administration’s biologics laboratories on location.
Pneumococcal infection is an infection caused by the bacterium Streptococcus pneumoniae.
Haemophilus meningitis is a form of bacterial meningitis caused by the Haemophilus influenzae bacteria. It is usually associated with Haemophilus influenzae type b. Meningitis involves the inflammation of the protective membranes that cover the brain and spinal cord. Haemophilus meningitis is characterized by symptoms including fever, nausea, sensitivity to light, headaches, stiff neck, anorexia, and seizures. Haemophilus meningitis can be deadly, but antibiotics are effective in treating the infection, especially when cases are caught early enough that the inflammation has not done a great deal of damage. Before the introduction of the Hib vaccine in 1985, Haemophilus meningitis was the leading cause of bacterial meningitis in children under the age of five. However, since the creation of the Hib vaccine, only two in every 100,000 children contract this type of meningitis. Five to ten percent of cases can be fatal, although the average mortality rate in developing nations is seventeen percent, mostly due to lack of access to vaccination as well as lack of access to medical care needed to combat the meningitis.

A vaccine-preventable disease is an infectious disease for which an effective preventive vaccine exists. If a person acquires a vaccine-preventable disease and dies from it, the death is considered a vaccine-preventable death.
The Pneumococcal Awareness Council of Experts (PACE) is a project of the Sabin Vaccine Institute and is composed of global experts in infectious diseases and vaccines. Established in December 2006, The Council seeks to raise awareness among policymakers and aims to secure global commitments to prevent pneumococcal disease, a leading infectious killer of children and adults worldwide. The Council works in collaboration and partnership with countries, NGOs, academia and industry.
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$870 million) in 2022 and the program covers all residents of India, including foreign residents.

Mission Indradhanush is a health mission of the Government of India. It was launched by Union Health Minister J. P. Nadda on 25 December 2014. The scheme this seeks to drive towards 90% full immunisation coverage of India and sustain the same by year 2022. Vaccination is being provided against eight vaccine-preventable diseases nationally, i.e. Diphtheria, Whooping Cough, Tetanus, Polio, Measles, severe form of Childhood Tuberculosis and Hepatitis B and meningitis & pneumonia caused by Haemophilus influenza type B; and against Rotavirus Diarrhea and Japanese Encephalitis in selected states and districts respectively.

Trudy Virginia Noller Murphy is an American pediatric infectious diseases physician, public health epidemiologist and vaccinologist. During the 1980s and 1990s, she conducted research at Southwestern Medical School in Dallas, Texas on three bacterial pathogens: Haemophilus influenzae type b (Hib), Streptococcus pneumoniae (pneumococcus), and methicillin-resistant Staphylococcus aureus (MRSA). Murphy's studies advanced understanding of how these organisms spread within communities, particularly among children attending day care centers. Her seminal work on Hib vaccines elucidated the effects of introduction of new Hib vaccines on both bacterial carriage and control of invasive Hib disease. Murphy subsequently joined the National Immunization Program at the Centers for Disease Control and Prevention (CDC) where she led multi-disciplinary teams in the Divisions of Epidemiology and Surveillance and The Viral Hepatitis Division. Among her most influential work at CDC was on Rotashield™, which was a newly licensed vaccine designed to prevent severe diarrheal disease caused by rotavirus. Murphy and her colleagues uncovered that the vaccine increased the risk of acute bowel obstruction (intussusception). This finding prompted suspension of the national recommendation to vaccinate children with Rotashield, and led the manufacturer to withdraw the vaccine from the market. For this work Murphy received the United States Department of Health and Human Services Secretary's Award for Distinguished Service in 2000, and the publication describing this work was recognized in 2002 by the Charles C. Shepard Science Award from the Centers for Disease Control and Prevention.
