The formulation of international requirements for the manufacture and control of BCG vaccine was first considered by the WHO Expert Committee on Biological Standardization in its thirteenth report. In its fourteenth report, the Committee requested WHO to make arrangements as soon as possible for the formulation of such requirements. These requirements were approved by the WHO Expert Committee on Biological Standardization at its eighteenth meeting and appeared as Annex 1 to its report. Mycobacterium tuberculosis (Mtb), the ethiological agent of tuberculosis (TB), is a leading cause of human disease and death, particularly in developing countries. In the global context, TB in intimately linked to poverty, and control of TB is ultimately a question of justice and human rights. In some areas with a high burden of TB, existing strategies for TB control are currently overwhelmed by the rising numbers of cases of TB occurring in parallel with or the HIV/AIDS pandemic. Emerging mycobacterial drug resistance is further complicating the situation. After decades of steady decline, the incidence of TB is also increasing in industralized countries, mainly as the result of outbreaks in particularly vulnerable groups. The bacille Calmette-Guérin (BCG) vaccine has existed for 80 years and is one of the most widely used of all current vaccines, reading >80%of neonates and infants in countries where it is part of the national childhood immunization programme. BCG vaccine has a documented p...

The BCG vaccine protects against tuberculosis, which is also known as TB. TB is a serious infection that affects the lungs and sometimes other parts of the body, such as the brain ( Who should have the BCG vaccine and when The BCG vaccine (which stands for Bacillus Calmette-Guérin vaccine) is not given as part of the routine It's given on the NHS only when a child or adult is thought to have an increased risk of coming into contact with TB. The BCG vaccine should only be given once in a lifetime. BCG for babies BCG vaccination is recommended for babies up to 1 year old who: • are born in areas of the UK where TB rates are high • have a parent or grandparent who was born in a country where there's a high rate of TB • live with, or are close contacts of, someone with infectious TB If the BCG vaccine is recommended for your baby, it will usually be offered at about 28 days old. This may be offered at a hospital, a local healthcare centre or, occasionally, at your GP surgery. BCG for children aged 16 and under BCG vaccination may also be recommended for older children who have an increased risk of developing TB, such as: • children who have a parent or grandparent who was born in a country where there's a high rate of TB • children who have recently arrived from countries with high levels of TB, including those in Africa, the Indian subcontinent, parts of southeast Asia, parts of South and Central America, and parts of the Middle East • children who will be living with local p...

Serious side effects are rare. Often, redness, swelling, and mild pain occur at the site of injection. The BCG vaccine was first used medically in 1921. See also: The main use of BCG is for vaccination against The most controversial aspect of BCG is the variable efficacy found in different clinical trials, which appears to depend on geography. Trials conducted in the UK have consistently shown a protective effect of 60 to 80%, but those conducted elsewhere have shown no protective effect, and efficacy appears to fall the closer one gets to the equator. A 1994 systematic review found that BCG reduces the risk of getting tuberculosis by about 50%. A systematic review and meta-analysis conducted in 2014 demonstrated that the BCG vaccin...

With BCG treatment, your healthcare provider delivers immunotherapy drugs directly to your bladder through a catheter. Unlike oral or injectable drugs, BCG treatment targets cancer cells inside of your bladder without having a negative impact on the rest of your body.

Tuberculosis (TB) is an infectious condition that can be fatal without treatment. It occurs following infection with the bacterium species Mycobacterium tuberculosis. The Bacille Calmette-Guérin (BCG) vaccine can help protect people from developing TB. However, in certain countries, such as the United States, health experts do not generally recommend using the vaccine. Although most TB cases occur in In this article, we discuss the safety and efficacy of the BCG vaccine and who should consider getting it. Share on Pinterest Matthew de Lange/Getty Images Mycobacterium tuberculosis (M.Tuberculosis) bacterium. It However, not every person with a TB infection will become ill. There are In cases of latent TB, a person’s immune system can fight the bacteria and prevent progression to TB disease. In contrast, an individual with a latent TB infection will experience no symptoms and cannot spread the infection to others. However, in other cases, the immune system cannot prevent the bacteria from multiplying. When the TB bacterium is active, experts refer to this as TB disease. In these cases, the bacterium causes people to experience symptoms such as The The BCG vaccine uses an Mycobacterium bovis, which scientists isolate from cows. This strain is similar enough to the human strain M.Tuberculosis to • soreness at the injection site • a small scar at the injection site • fever • headache • swollen glands While rare, more serious complications can include allergic reactions, abscess...

Merck & Co. is the only pharmaceutical company that makes and supplies the BCG treatment in the United States and many other countries around the world. Due to the rising demand for the vaccine over the past several years, there have been global shortages of the drug. The company is actively working on building a new manufacturing facility, though it will be several years before it is creating BCG. Because of the ongoing shortage of BCG, new guidelines from the American Urological Association aim to make BCG available to those patients with the greatest need. These guidelines prioritize the highest-risk patients to receive full doses of the BCG treatment while suggesting that lower-risk patients can be treated with intravesical chemotherapy instead. Once the treatment is infused, your doctor or nurse will remove the catheter. They’ll have you lie on your back, each side, and your stomach for 15 minutes each. The BCG mycobacteria needs to touch the bladder cancer cells to activate the immune system. You’ll then be free to go but will need to hold off on peeing for another hour. • Swelling of the lymph nodes, which you may feel under the skin • Flu-like symptoms, including fatigue, fever, aches, and chills • Urine that is red or brown in color from bleeding in the bladder or urethra • Burning in the bladder, pain while peeing, difficulty peeing, frequent peeing • Digestive symptoms including upset stomach and vomiting • Surgery to remove the tumor: Early cancers can be remov...

Before taking this medicine You should not receive BCG vaccine if you are allergic to it, or if you have a weak immune system caused by: • HIV or AIDS; • • chemotherapy or radiation; or • steroid medication. Tell your doctor if you have ever had: • a positive TB skin test; or • an inherited immune system problem (in you or a family member). It is not known whether BCG vaccine will harm an unborn baby. However, this vaccine is not recommended for pregnant women. Do not breastfeed. How is BCG vaccine given? Before you receive BCG vaccine, your doctor will perform a skin test to make sure you do not have tuberculosis. BCG vaccine is not given with a needle and syringe, as most other vaccines are. Instead, the BCG vaccine is a liquid placed directly onto the skin of your upper arm. Then a multi-pronged needle device is used to prick the skin through the liquid to deliver the vaccine into the shallow layers of skin. These needle sticks are not deep, but they will cause some soreness and minor bleeding. You may have flu-like symptoms for up to 2 days after you receive BCG vaccine. Call your doctor at once if you have a Within 10 to 14 days after receiving this vaccine, you should see small red bumps on your skin where the vaccine and needle device were placed. This red area will gradually grow larger after 4 to 6 weeks, and then scale and fade. After 6 months you will most likely have little to no scar. BCG vaccine contains a live form of tuberculosis bacteria, which can "shed" ...
