Bacillus Calmette–Guérin (BCG) vaccine is a vaccine primarily used against tuberculosis (TB). It is named after its inventors Albert Calmette and Camille Guérin. In countries where tuberculosis or leprosy is common, one dose is recommended in healthy babies as soon after birth as possible. In areas where tuberculosis is not common, only children at high risk are typically immunized, while suspected cases of tuberculosis are individually tested for and treated. Adults who do not have tuberculosis and have not been previously immunized, but are frequently exposed, may be immunized, as well. BCG also has some effectiveness against Buruli ulcer infection and other nontuberculous mycobacterial infections. Additionally, it is sometimes used as part of the treatment of bladder cancer.
Tuberculosis (TB) is an infectious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. Tuberculosis generally affects the lungs, but it can also affect other parts of the body. Most infections show no symptoms, in which case it is known as latent tuberculosis. Around 10% of latent infections progress to active disease which, if left untreated, kill about half of those affected. Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. It was historically referred to as consumption due to the weight loss associated with the disease. Infection of other organs can cause a wide range of symptoms.
MVA85A is a vaccine against tuberculosis developed by researchers led by Professor Helen McShane at Oxford University. This vaccine produces higher levels of long-lasting cellular immunity when used together with the older TB vaccine BCG. Phase I clinical trials were completed and then phase II clinical trials took place in South Africa. Efficacy trials ran in parallel from 2009 to 2019.
Tuberculosis (TB) vaccines are vaccinations intended for the prevention of tuberculosis. Immunotherapy as a defence against TB was first proposed in 1890 by Robert Koch. Today, the only effective tuberculosis vaccine in common use is the Bacillus Calmette-Guérin (BCG) vaccine, first used on humans in 1921. About three out of every 10,000 people who get the vaccine experience side effects, which are usually minor except in severely immuno-depressed individuals. While BCG immunization provides fairly effective protection for infants and young children, its efficacy in adults is variable, ranging from 0% to 80%. Several variables have been considered as responsible for the varying outcomes. Demand for TB immunotherapy advancement exists because the disease has become increasingly drug-resistant.
The Oxford Vaccine Group (OVG) is a vaccine research group within the Department of Paediatrics at the University of Oxford. It was founded in 1994 by Professor E. Richard Moxon, was initially based at the John Radcliffe Hospital, and moved in 2003 to its current location in the Centre for Clinical Vaccinology and Tropical Medicine (CCVTM) at the Churchill Hospital in Oxford, England. The group, led by Professor Andrew Pollard since 2001, comprises around 75 members across a number of disciplines, including consultants in paediatrics and vaccinology, clinical research fellows, research nurses, statisticians, post-doctoral laboratory scientists, research assistants and DPhil students.

Hazel Marguerite Dockrell is an Irish-born microbiologist and immunologist whose research has focused on immunity to the human mycobacterial diseases, leprosy and tuberculosis. She has spent most of her career at the London School of Hygiene and Tropical Medicine, where as of 2020 she is a professor of immunology. She was the first female president of the Royal Society of Tropical Medicine and Hygiene. Jimmy Whitworth of the Wellcome Trust describes her as "a marvellous ambassador for global health and research."
The Jenner Institute is a research institute on the Old Road Campus in Headington, east Oxford, England. It was formed in November 2005 through a partnership between the University of Oxford and the UK Institute for Animal Health. It is associated with the Nuffield Department of Medicine, in the Medical Sciences Division of Oxford University. The institute receives charitable support from the Jenner Vaccine Foundation.
