- The main use of BCG is for vaccination against tuberculosis. (wikipedia.org)
- BCG vaccination can cause a false positive Mantoux test. (wikipedia.org)
- Reasons for this policy in the United States include low TB incidence, varying effectiveness of the vaccine against adult pulmonary TB, and potential for vaccination to cause a false positive TB skin test. (cdc.gov)
- Prior BCG vaccination has been associated with increased cytokine production in response to exposure to multiple non-TB pathogens. (cdc.gov)
- These epigenetic changes and increases in cytokine production have been shown to persist at least three months after vaccination . (cdc.gov)
- However, further study is required to determine how other factors such as age at vaccination affect BCG-induced trained immunity. (cdc.gov)
- The concern of the public health community about the resurgence and changing nature of TB in the United States prompted a re-evaluation of the role of BCG vaccination in the prevention and control of TB. (cdc.gov)
- The use of BCG vaccine has been limited because a) its effectiveness in preventing infectious forms of TB is uncertain and b) the reactivity to tuberculin that occurs after vaccination interferes with the management of persons who are possibly infected with M. tuberculosis. (cdc.gov)
- In the United States, the use of BCG vaccination as a TB prevention strategy is reserved for selected persons who meet specific criteria. (cdc.gov)
- BCG vaccination should be considered for infants and children who reside in settings in which the likelihood of M. tuberculosis transmission and subsequent infection is high, provided no other measures can be implemented (e.g., removing the child from the source of infection). (cdc.gov)
- In addition, BCG vaccination may be considered for health-care workers (HCWs) who are employed in settings in which the likelihood of transmission and subsequent infection with M. tuberculosis strains resistant to isoniazid and rifampin is high, provided comprehensive TB infection-control precautions have been implemented in the workplace and have not been successful. (cdc.gov)
- BCG vaccination is not recommended for children and adults who are infected with human immunodeficiency virus because of the potential adverse reactions associated with the use of the vaccine in these persons. (cdc.gov)

- ABSTRACT Previous work with small-animal laboratory models of tuberculosis has shown that vaccination strategies based on heterologous prime-boost protocols using Mycobacterium bovis bacillus Calmette-Guérin (BCG) to prime and modified vaccinia virus Ankara strain (MVA85A) or recombinant attenuated adenoviruses (Ad85A) expressing the mycobacterial antigen Ag85A to boost may increase the protective efficacy of BCG. (ox.ac.uk)
- Either Ad85A or MVA85A boosting resulted in protection superior to that given by BCG alone: boosting BCG with MVA85A or Ad85A induced significant reduction in pathology in four/eight parameters assessed, while BCG vaccination alone did so in only one parameter studied. (ox.ac.uk)
- Analysis of vaccine-induced immunity identified memory responses measured by cultured enzyme-linked immunospot assay as well as in vitro interleukin-17 production as predictors of vaccination success, as both responses, measured before challenge, correlated positively with the degree of protection.

Adjuvant4
- Meanwhile, the potential of biogenic SeNPs as an immunomodulatory agent besides the conventional adjuvant in the formulation of the hepatitis B surface antigen (HBsAg) vaccine model has been studied in our previous research, and results showed a promising potential for these nanoparticles to be used in the vaccine formulation [8]. (nanobe.org)
- Although alum is used as a common adjuvant in hepatitis B surface antigen (HBsAg) vaccine formulation to induce a humoral immune response, it is less effective in stimulating a Th1 response [17, 18]. (nanobe.org)
- To handle this challenge, many under investigational vaccines are mixed with a potent adjuvant as an immune modulator agent in parallel with HBs antigen [19]. (nanobe.org)
- The vaccine with BCG has been used as adjuvant therapy, but a significant portion of patients still present recurrence of the disease. (fapesp.br)
Antigens2
- It is pertinent to note that COVISHIELD (SII-ChAdOx1 nCoV-19) vaccine contains the replication-deficient simian adenovirus vector ChAdOx1, containing the structural surface glycoprotein (Spike protein) antigens of SARS-CoV-2. (siasat.com)
- On day 25 p.i., the BCG plus Leishmania- or BCG-treatment of mice abolished the capacity of spleen cells to produce IL-10 in response to T. cruzi antigens. (ac.be)
Bacterial vaccine1
- Wait until Abx Tx complete to administer live bacterial vaccine. (medscape.com)
Viral1
- The bacterial loads in lymph node tissues were also reduced after viral boosting of BCG-vaccinated calves compared to those in BCG-only-vaccinated animals. (ox.ac.uk)
Live4
- Do not administer live vaccines 30 days before or concurrently with belimumab. (medscape.com)
- Do not give live vaccines concurrently with certolizumab. (medscape.com)
- Live-attenuated vaccines should be avoided for at least 3 mo after cessation of immunosuppressive therapy. (medscape.com)
- The Lübeck disaster (1929-33) saw many children inoculated with live BCG instead of the killed vaccine, resulting in thousands of children affected and several deaths. (somee.social)
Reduces1
- The poly(A) tail is encoded in the DNA template, which eliminates reaction steps and reduces overall production time and material loss [19] . (researchgate.net)
Neonatal mortality2
- To improve our understanding of the non-specific beneficial effects of BCG on all-cause neonatal mortality, Kristoffer has conducted epidemiological studies on the temporal, seasonal, sex-differential and formulation-specific dependency of the vaccine effects. (frederiksberghospital.dk)

- Kalorama's Vaccines: The World Market breaks down the market for pediatric and adult vaccines, providing background information, revenue numbers, and a discussion of critical trends that anyone seeking opportunities in vaccines will need to be aware of. (marketresearch.com)
Newborns7
- Why is the 100-year-old BCG vaccine so broadly protective in newborns? (greeninnovationhub.com)
- The findings provide clues toward making other vaccines more effective in vulnerable populations with distinct immune systems, such as newborns. (greeninnovationhub.com)
- First author Joann Diray Arce, Ph.D., and her colleagues began with blood samples from low-birthweight newborns in Guinea Bissau who were enrolled in a randomized clinical trial to receive BCG either at birth or after a delay of six weeks. (greeninnovationhub.com)
- They found that BCG vaccines given at birth changed metabolite and lipid profiles in newborns' blood plasma in a pattern distinct from those in the delayed-vaccine group. (greeninnovationhub.com)
- The researchers had parallel findings when they tested BCG in cord blood samples from a cohort of Boston newborns and samples from a separate NIH/NIAID-funded Human Immunology Project Consortium study of newborns in The Gambia and Papua New Guinea. (greeninnovationhub.com)
- It's critical that we learn from BCG to better understand how to protect newborns. (greeninnovationhub.com)
- The MTBVAC-Newborns study will determine whether a weakened form of the TB bacterium is suitable for large-scale trials - potentially offering a better alternative to BCG. (edctp.org)
Protective effects1
- An early observation that countries where the BCG vaccine is frequently used reported lower numbers of COVID-19 cases compared with other countries sparked interest in the hypothesis that BCG vaccine has protective effects against COVID-19. (cdc.gov)
Populations1
- The United States, Canada, Australia, and many western European countries do not include the vaccine in general childhood vaccine programs, offering it only to certain high-risk populations . (cdc.gov)
