BCG vaccine is an attenuated, live bacterial culture of the Bacillus of Calmette and Guérin (BCG) strain of Mycobacterium bovis and induces active immunity against Mycobacterium tuberculosis.
Use: Labeled Indications
Mycobacterium tuberculosis disease prevention: Active immunization against Mycobacterium tuberculosis in persons not previously infected and who are at high risk for exposure
BCG vaccine is not routinely administered for the prevention of M. tuberculosis in the United States. The Advisory Committee on Immunization Practices (ACIP) recommends vaccination be considered for the following (CDC/ACIP [Villarino 1996]):
- Infants and children with a negative tuberculin skin test who are continually exposed to (and cannot be separated from) patients who are untreated or ineffectively treated for infectious pulmonary TB disease when the child cannot be given long-term treatment for infection or if the patient has infectious pulmonary TB caused by strains resistant to isoniazid and rifampin.
- Health care workers with a high percentage of patients with M. tuberculosis strains resistant to both isoniazid and rifampin, if there is ongoing transmission of the resistant strains and subsequent infection is likely, or if comprehensive infection-control precautions have not been successful. In addition, health care workers should be counseled on the risks and benefits of vaccination and treatment of latent TB infection
The Advisory Council for the Elimination of Tuberculosis (ACET) recommends BCG vaccination for health care and humanitarian workers who travel to work where the incidence of multidrug-resistant tuberculosis is high and potential transmission may occur. The ACET recommends a set of risk-reduction measures for such workers, noting that interferon-gamma release assays can differentiate tuberculosis infection from BCG vaccination effect (Seaworth 2014).
Off Label Uses
Prevention of leprosy
Evidence from meta-analyses of controlled trials, cohort studies, and case-control studies indicate that the use of BCG vaccine is partially protective in the prevention of leprosy. Data are limited by high levels of heterogeneity for experimental trials and case-control studies.
Prior hypersensitivity to the vaccine or any component of the formulation; immunosuppressed patients or persons with congenital or acquired immune deficiencies (eg, HIV infection, leukemia, lymphoma, cancer therapy, immunosuppressive therapy such as corticosteroids); active tuberculosis
Note: Dosing and administration based on US percutaneous product (TICE strain); formulation/dosing/route may vary in other regions around the globe (consult local product labeling).
Immunization against tuberculosis: Percutaneous: 0.2 to 0.3 mL (full-strength dilution); conduct postvaccinal tuberculin test (5 TU of PPD) in 2 to 3 months; if test is negative, repeat vaccination. Note: Initial lesions usually appear after 10 to 14 days and consist of small, red papules at injection site, which reach maximum diameter of 3 mm in 4 to 6 weeks.
Prevention of leprosy (off-label use): Percutaneous: 0.2 to 0.3 mL (full-strength dilution); a single dose offers partial protection against leprosy; an additional dose may confer greater protection, however, studies do not specify appropriate interval (Bertolli 1997; Karonga Prevention Trial Group 1996; Setia 2006; Zodpey 2007). Note: Timing of vaccination and chemoprophylaxis should be taken into consideration since chemoprophylaxis may kill BCG (Rodrigues 2011).
Refer to adult dosing.
Note: Dosing and administration based on US percutaneous product (TICE strain); formulation/dosing/route may vary in other regions (consult local product labeling). According to ACIP, doses administered ≤4 days before minimum interval or age are considered valid; however, local or state mandates may supersede this timeframe (ACIP [Kroger 2017]).
Immunization against tuberculosis: Infants, Children, and Adolescents: Percutaneous: Full-strength: 0.2 to 0.3 mL as a single dose; conduct postvaccinal tuberculin test (5 TU of PPD) in 2 to 3 months; if test is negative, repeat vaccination (at age ≥1 year). Note: Initial lesion usually appears after 10 to 14 days consisting of small, red papule at injection site and reaches maximum diameter of 3 mm in 4 to 6 weeks.
Leprosy, prophylaxis in areas with high incidence: Limited data available (Setia 2006; Zodbey 2007): Infants, Children, and Adolescents with no evidence of immunity: Percutaneous: Full-strength: 0.2 to 0.3 mL as a single dose (WHO 2017)
Prepare using aseptic technique. Do not prepare parenteral medications in an area where BCG has been prepared. Do not filter. Reconstitute with 1 mL of SWFI; swirl gently, do not vigorously shake. For children <1 month, reconstitute with 2 mL SWFI.
Note: Administration based on US percutaneous product (TICE strain); formulation/dosing/route may vary in other regions around the globe (consult local product labeling).
Should only be given percutaneously; do not administer IV, SubQ, IM, or intradermally. Do not mix with other vaccines or injections; separate needles and syringes should be used for each injection (ACIP [Kroger 2017]).
Apply vaccine with syringe and needle by dropping onto 1 to 2 inch area of horizontally positioned surface of cleansed, dry site (deltoid region of arm preferred); pulling skin tight, puncture skin with multiple puncture device centered over the vaccine; apply pressure for 5 seconds (do not "rock" device). After successful puncture, spread vaccine evenly using the edge of the device over puncture area; an additional 1 to 2 drops of vaccine may be added to ensure a very wet vaccination site. Apply loose covering and keep dry for 24 hours.
When used for immunization against tuberculosis, US federal law requires that the name of medication, date of administration, the vaccine manufacturer, lot number of vaccine, and the administering person's name, title, and address be entered into the patient's permanent medical record.
Store intact vials at 2°C to 8°C (36°F to 46°F). Protect from sunlight. Store reconstituted vaccine in refrigerator; use within 2 hours of mixing. Do not freeze vaccine after reconstitution.

Management: If a parenteral live vaccine has been recently administered, a scheduled PPD skin test should not be administered for at least 4-6 weeks following the administration of the vaccine. Consider therapy modification
Vaccines (Live): May diminish the therapeutic effect of other Vaccines (Live). Management: Two or more injectable or nasally administered live vaccines not administered on the same day should be separated by at least 28 days (ie, 4 weeks). If not, the vaccine administered second should be repeated at least 4 week later. Exceptions: Adenovirus (Types 4, 7) Vaccine; Cholera Vaccine; Rotavirus Vaccine. Monitor therapy
Venetoclax: May enhance the adverse/toxic effect of Vaccines (Live). Venetoclax may diminish the therapeutic effect of Vaccines (Live). Management: Avoid use of live, attenuated vaccines before, during, or after (prior to B-cell recovery) venetoclax treatment. Avoid combination
PPD intradermal test: BCG results in reactive tuberculin skin test; rule out active tuberculosis prior to initiating intravesicular BCG treatment. BCG vaccine may be administered to persons with a PPD reaction of <5 mm induration; PPD should be used again 2 to 3 months after vaccination to ensure reactivity to vaccine (document in mm of induration). Vaccinees with a positive PPD test (>5 mm) should not be tested again unless exposed to tuberculosis. In this situation, an increase of induration may indicate a newly acquired TB infection. Vaccinees with a negative PPD test (<5 mm induration) may continue periodic skin testing as long as the results remain <5 mm (CDC/ACIP, [Villarino 1996]).
Interferon-gamma release assay (IGRA) tests for latent TB infection (LTBI) are not affected by BCG vaccination history and are considered acceptable for monitoring occupational exposures in healthcare workers (Mazurek 2010).
Following vaccination, all serious adverse reactions must be reported to the US Department of Health and Human Services (DHHS) Vaccine Adverse Event Reporting System (VAERS) 1-800-822-7967 or online at https://vaers.hhs.gov/esub/index. Local reactions may persist for up to 3 months; more severe manifestations may occur up to 5 months after vaccination and persist for several weeks.
Frequency not defined.
Dermatologic: Pustules (at injection site), skin ulceration at injection site
Hematologic & oncologic: Auxillary lymphadenopathy, cervical lymphadenopathy, lymphadenitis (includes local and suppurative)
Infection: BCG infection (BCG osteomyelitis; may occur from 4 months to 2 years after vaccination)
Local: Induration at injection site, injection site lesion, itching at injection site, tenderness at injection site
Respiratory: Flu-like symptoms
Concerns related to adverse effects:
• Anaphylactoid/hypersensitivity reactions: Immediate treatment (including epinephrine 1 mg/mL) for anaphylactoid and/or hypersensitivity reactions should be available during vaccine use (ACIP [Kroger 2017]).
• BCG reaction: Local adverse effects may include moderate axillary or cervical lymphadenopathy and induration/pustule formation at the injection site; lasting as long as 3 months or more. Severe ulceration, regional suppurative lymphadenitis with draining sinuses, and caseous lesions or purulent drainage may occur within 5 months and persist for several weeks. Systemic adverse effects lasting 1 to 2 days and similar to a flu-like syndrome (fever, anorexia, myalgia, and neuralgia) are generally caused by hypersensitivity to the vaccine.
• Disseminated infections: May cause BCG infection, particularly in immunocompromised patients. If signs and symptoms of a systemic BCG infection occur (eg, fever of ≥103°F or acute local reactions lasting longer than 2 to 3 days), permanently discontinue BCG vaccination and begin therapy with ≥2 antimycobacterial agents while conducting a diagnostic evaluation. Infection from vaccine is not sensitive to pyrazinamide. BCG osteomyelitis affecting the epiphyses of the long bones is the most common disseminated infection and may occur 4 months to 2 years after vaccination.
• Syncope: Syncope has been reported with use of injectable vaccines and may result in serious secondary injury (eg, skull fracture, cerebral hemorrhage); typically reported in adolescents and young adults and within 15 minutes after vaccination. Procedures should be in place to avoid injuries from falling and to restore cerebral perfusion if syncope occurs (ACIP [Kroger 2017]).
• Acute illness: The decision to administer or delay vaccination because of current or recent febrile illness depends on the severity of symptoms and the etiology of the disease. Defer administration in patients with moderate or severe acute illness (with or without fever); vaccination should not be delayed for patients with mild acute illness (with or without fever) (ACIP [Kroger 2017]).
• HIV: Use is contraindicated in HIV-infected persons (ACIP [Kroger 2017]). Should be administered with caution to persons in groups at high risk for HIV. HIV-infected persons thought to be infected with Mycobacterium tuberculosis should be strongly recommended for tuberculosis preventive therapy.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Vaccines: In order to maximize vaccination rates, the ACIP recommends simultaneous administration (ie, >1 vaccine on the same day at different anatomic sites) of all age-appropriate vaccines (live or inactivated) for which a person is eligible at a single clinic visit, unless contraindications exist (ACIP [Kroger 2017]).
• Altered immunocompetence: Use is contraindicated in immunocompromised patients (eg, patients receiving chemo/radiation therapy or other immunosuppressive therapy [including high-dose corticosteroids]). Household and close contacts of persons with altered immunocompetence may receive most age appropriate vaccines (ACIP [Kroger 2017]). Live vaccines should be administered ≥4 weeks prior to planned immunosuppression and avoided within 2 weeks of immunosuppression when feasible; live vaccines should not be administered for at least 3 months after immunosuppressive therapy (ACIP [Kroger 2017]; (IDSA [Rubin 2014]).
• Positive PPD reaction: Determine PPD status prior to use. BCG vaccination is not recommended for persons with a positive PPD reaction.
• Biohazard agent: Contains live, attenuated mycobacteria. Use appropriate precautions for handling and disposal. BCG is a biohazard; proper preparation technique, handling, and disposal of all equipment in contact with BCG as a biohazard material is recommended. BCG infections have been reported in healthcare workers due to accidental exposure (needlestick, skin laceration); nosocomial infections have been reported in patients receiving parenteral medications prepared in areas where BCG was prepared. To avoid cross contamination, do not prepare parenteral medications in an area where BCG has been prepared.
• Antipyretics: Antipyretics have not been shown to prevent febrile seizures; antipyretics may be used to treat fever or discomfort following vaccination (ACIP [Kroger 2017]). One study reported that routine prophylactic administration of acetaminophen prior to vaccination to prevent fever decreased the immune response of some vaccines; the clinical significance of this reduction in immune response has not been established (Prymula 2009).
• Appropriate use: BCG vaccine should not be used for the active treatment of tuberculosis.
• Effective immunity: Vaccination may not result in effective immunity in all patients. Response depends upon multiple factors (eg, type of vaccine, age of patient) and may be improved by administering the vaccine at the recommended dose, route, and interval. Vaccines may not be effective if administered during periods of altered immune competence (ACIP [Kroger 2017]).
PPD test prior to vaccination. Flu-like symptoms ≥72 hours, fever ≥103°F, acute local reactions lasting >2 to 3 days. Monitor for anaphylaxis and syncope for 15 minutes following administration (ACIP [Kroger 2017]). If seizure-like activity associated with syncope occurs, maintain patient in supine or Trendelenburg position to reestablish adequate cerebral perfusion.
Animal reproduction studies have not been conducted. BCG vaccine is not recommended for use in pregnant women. Because of the theoretical risk to the fetus, women known to be pregnant generally should not receive live, attenuated virus vaccines; avoid conception for 4 weeks after vaccination with live vaccines (ACIP [Kroger 2017]).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience loss of strength and energy or swollen glands. Have patient report immediately to prescriber flu-like symptoms longer than 2 days, bone pain, severe fever, skin ulcers, or severe injection site irritation, redness, pain, or edema (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
