What You'll Learn
BCG vaccine is for tuberculosis (TB)
The Bacille Calmette-Guérin (BCG) vaccine is a vaccine for tuberculosis (TB). It is the only vaccine available against TB and is the most widely administered vaccine globally. It is typically part of the routine newborn immunization schedule, although it can be administered to people of any age. The BCG vaccine is not generally used in the United States due to the low incidence of TB infections. However, it may be considered for individuals who meet specific criteria and in consultation with a TB expert.
The BCG vaccine was first administered to humans in 1921 and remains in use a century later. It is a live attenuated vaccine form of Mycobacterium bovis, which can also protect against non-tuberculous mycobacterial infections like leprosy and Buruli ulcer. The vaccine has been shown to reduce the risk of developing TB by about 50% and is especially effective in preventing miliary TB and TB meningitis.
The efficacy of the BCG vaccine varies depending on geographical location. Trials in the UK consistently show a 60% to 80% protective effect, while trials conducted elsewhere have shown little to no protective effect. This variability may be due to factors such as genetic differences in populations, environmental changes, exposure to other bacterial infections, and conditions in the laboratory where the vaccine is grown.
The BCG vaccine is generally safe, and severe complications are rare. However, it is not recommended for individuals who are immunocompromised or likely to become immunocompromised, such as those with HIV or candidates for organ transplants. Pregnant women should also not receive the BCG vaccination, although no harmful effects on the fetus have been observed. In rare cases, regional bone infection (BCG osteomyelitis or osteitis) and disseminated BCG infection can occur as complications of the vaccine, and these can be potentially life-threatening.
Regarding immunization records, individuals can typically access their records through their local health authority or healthcare provider. In some regions, immunization records are provided as a paper record at the time of immunization, and individuals can also request records from their immunization provider if they have moved from another province or country. Immunization records provide a history of all the vaccines an individual has received, and in the absence of these records, individuals are considered unimmunized and unprotected.

BCG is not recommended for routine use in Canada
Immunization records provide a history of all the vaccines a person has received. In Canada, these records can be accessed through the Health Gateway, which includes immunizations given at public health clinics and pharmacies in British Columbia. However, it is important to note that the Health Gateway does not show immunizations given by other healthcare providers, such as family doctors or nurse practitioners, or those administered outside of BC.
Regarding the BCG vaccine specifically, it is not recommended for routine use in Canada. The Bacille Calmette-Guérin (BCG) vaccine has been used for nearly a century, but its efficacy remains controversial due to variations in BCG substrains and vaccine effectiveness. While most experts agree that BCG is effective against severe forms of childhood tuberculosis (TB), its effectiveness against TB in adults is highly variable. As a result, different countries have developed varying BCG vaccination policies.
In Canada, the approach to BCG vaccination has been influenced by this uncertainty and has also been complicated by differing policies across provinces. Some provinces have implemented mass vaccination programs, while others have not. Overall, Canada has not advocated for universal BCG vaccination and instead recommends it only for high-risk groups. This decision is informed by the variable efficacy of the vaccine in adults and the need to consider the specific context and needs of the Canadian population.
It is important to consult official Canadian health sources, such as the Public Health Agency of Canada, for the most up-to-date and accurate information regarding BCG vaccination policies and recommendations in the country. Additionally, individuals seeking personal medical advice should consult their healthcare providers, who can provide guidance tailored to their specific circumstances.

BCG is not generally used in the US
Immunization records, or vaccination records, provide a history of all the vaccines a person has received. However, immunization records may not show all vaccinations, especially if they were administered by certain healthcare providers or outside of a particular region.
The Bacille Calmette-Guérin (BCG) vaccine is primarily used to prevent tuberculosis (TB) disease. While the BCG vaccine is commonly used in countries where TB is prevalent, it is not generally administered in the United States for several reasons:
- Low Risk of TB Infection: The United States has a relatively low risk of infection with TB bacteria compared to other countries.
- Variable Effectiveness: The BCG vaccine's effectiveness in preventing adult pulmonary TB, which is the most common form of TB in adults, has been questioned. It is believed that the vaccine given in childhood may not effectively prevent the development of adult pulmonary TB.
- False-Positive TB Tests: The BCG vaccine can cause false-positive results on TB skin tests, complicating the interpretation of test results and treatment decisions. However, it is important to note that blood tests for TB infection are less likely to produce false positives due to prior BCG vaccination.
- Alternative Prevention Measures: Instead of widespread BCG vaccination, the focus in the United States is on preventing the spread of TB through other measures. This includes recommending the vaccine only for specific high-risk groups, such as healthcare workers in certain settings or individuals with no known risk factors for TB.
- Drug Resistance: The decision to administer the BCG vaccine to healthcare workers is considered on an individual basis, especially in settings with drug-resistant TB strains. The potential risks and benefits of BCG vaccination and the treatment of latent TB infection are carefully evaluated for each case.
It is important to note that the decision to endorse the widespread use of any vaccination, including BCG, is influenced by various factors, including regional differences in TB patterns, variations in health systems, and local history and opinions. While TB incidence is rising in the US, experts believe that there is currently insufficient evidence to support the need for BCG immunization to become a popular choice.

BCG may be considered for infants in high-risk communities
Immunization records, also called vaccination records, provide a history of all the vaccines a person has received. These records are important as people without them are considered unimmunized and unprotected. In Canada, for instance, immunization records can be accessed, downloaded, and printed through the Health Gateway. However, these records only show immunizations given at public health clinics and pharmacies in British Columbia (BC). Immunizations administered by other healthcare providers, such as family doctors or outside BC, are not included.
In certain circumstances, the BCG vaccine may be considered for infants in high-risk communities. The BCG vaccine is not recommended for routine use in any Canadian population. However, in the absence of early detection and treatment programs for latent TB infection, the BCG vaccine may be considered for infants in high-risk communities. This includes infants residing in populations with a high annual risk of TB infection, such as First Nations and Inuit communities with a high incidence of infectious TB.
The World Health Organization (WHO) has published guidelines for the use of the BCG vaccine in infants at risk for HIV infection, as there is a high risk of disseminated BCG disease developing in HIV-infected infants. The Canadian guidelines also emphasize the importance of HIV testing in the mother before administering the BCG vaccine to infants. Additionally, immunocompromised persons and pregnant women should not receive the BCG vaccine due to its live vaccine nature.
While the BCG vaccine has been routinely administered to newborns in First Nations communities, there has been a shift towards more selective vaccination programs for high-risk groups. This change has been accompanied by a higher rate of atypical mycobacterial infection in the non-vaccinated population. As a result, ongoing support and enhanced detection and treatment programs are crucial to ensure the well-being of infants in these communities.

BCG can cause a false positive TB skin test
Immunization records, also known as vaccination records, provide a history of all the vaccines a person has received. In most places, a paper record is given at the time of immunization. In some places, like British Columbia (BC), immunization records can be accessed, downloaded, and printed through an online portal.
The Bacille Calmette-Guérin (BCG) vaccine is a vaccine for tuberculosis (TB) but is not generally used in the United States. However, it is used in many other countries. The BCG vaccine may cause a false-positive reaction in TB skin tests. This means that a person who has received the BCG vaccine may test positive for TB infection on a skin test even though they are not infected with TB bacteria. There is currently no reliable way to distinguish between a positive TB skin test reaction caused by the BCG vaccine and a reaction caused by a true TB infection. As such, people who have been vaccinated with BCG should be further evaluated for latent TB infection or TB disease as if they were not vaccinated.
The TB skin test should be placed and read by a designated, trained healthcare provider. The test is placed on the skin and then read after a certain amount of time has passed, typically 48 to 96 hours. The test result is based on the amount of swelling or induration at the site where the test was placed. In individuals who have received the BCG vaccine, the amount of swelling may be greater, leading to a false-positive result. This effect of the BCG vaccine on TB skin test results has been observed in multiple studies.
It is important to note that the TB skin test is not the only method of testing for TB infection. TB blood tests, such as the interferon-gamma release assay (IGRA), are preferred for people who have received the BCG vaccine, as these tests are not affected by the vaccine.
