The Adverse Events, Signs, and Management of Neonatal Bacillus Calmette-Guérin Vaccine Overdose.

“A two-day-old male neonate was inadvertently immunized with 20-times the recommended dose of Bacillus Calmette-Guérin (BCG) vaccine (1.0 ml instead of 0.05 ml).”

Adverse reactions to BCG.

“In the post-war period the following BCG vaccines were successively in use for preventive vaccination in the Czech territory: (a) Copenhagen BCG, 1947-1950, (b) Prague BCG 725, 1951-1980, (c) Moscow BCG, 1981-1993, and (d) Behring BCG, from 1994 onwards. These BCG substrains can be now identified by modern methods of molecular genetics. Introducing the Moscow BCG brought about an elevated incidence of iatrogenic local and regional lymph node adverse reactions compared with the previous Prague BCG product and, as a new phenomenon, bone and joint involvements in children vaccinated at birth. The aim of this study was to analyze the incidence of postvaccination adverse reactions reported in the period from 1981 to 1993 as related to the Moscow BCG vaccine and, to demonstrate the effect of lower vaccination dosage on their frequency. The concentration of the Moscow BCG varied from 11 to 22.6 x 10(6) (average 16.2) CFU per 1 mg. In the period when full dose of BCG (0.05 mg per 0.1 ml) was applied to newborns 437 local and 195 regional lymph node complications were recorded, i.e. 0.08% of vaccinated were affected, demanding antituberculosis chemotherapy in 6.5% and surgical interventions in 24%. When the lowered vaccination dose (0.025 mg per 0.1 ml) was inoculated to newborns the local adverse reactions rose paradoxically affecting 0.1% of vaccinated but the regional lymph node reactions fell considerably to reach 0.01%; the demand for chemotherapy and surgery also fell down to 3.1 and 4.8% respectively. Bone and joint adverse involvements were recorded in 28 cases, i.e. in 3.7 per 10(5) of those vaccinated with the full dose.”

Bacillus Calmette-Guérin reactivation as a sign of incomplete Kawasaki disease.

“An early and specific clinical sign, not included in the classical diagnosis criteria, but that can be very useful in the diagnosis of KD, is the reaction at the Bacillus Calmette-Guérin (BCG) inoculation site. We describe a case of a 4-month-old boy, fully immunised, whose BCG scar reactivation led to the diagnosis of IKD. This case-report emphasises the importance of BCG site reactivation in establishing a diagnosis of IKD that clinicians should be aware of, especially in countries where BCG vaccination is still part of the immunisation schedule.

Borderline tuberculoid leprosy following BCG vaccination. A case report.

“Borderline tuberculoid leprosy was diagnosed clinically and histologically in a four year-old boy about 6 months after intradermal vaccination with BCG. His mother reported that a lesion began to appear above the vaccination site on the arm 2 weeks after the vaccination, and a second lesion appeared on the chin 2 months later. Responses in the lymphocyte transformation test to sonicated Mycobacterium leprae, BCG, and to PPD were consistent with a tuberculoid leprosy infection. Precipitation of BT leprosy by intradermal BCG infection may possibly represent the overcoming of a phase of primary suppression in an individual who might otherwise have progressed toward lepromatous leprosy. The implications of this hypothesis for the planning of a controlled trial of an anti-leprosy vaccine are discussed.”

Mycobacterium bovis lymphadenitis complicating BCG immunization in an infant with symptomatic HIV-1 infection.

“A 3-month-old infant with HIV-1 infection who recently immigrated from Ethiopia developed regional lymphadenitis and systemic symptoms subsequent to BCG immunization. She was suffering from axillary lymphadenitis ipsilateral to the BCG vaccination site, failure to thrive, unresolving fever and hepatosplenomegaly. Acid-fast bacilli were seen on staining and Mycobacterium bovis was isolated from the regional lymph node. The infant responded promptly to triple antituberculous therapy but died 2 months later from overwhelming pneumonia and respiratory failure. This case emphasizes the iatrogenic hazards of BCG immunization in HIV-1 infected infants. With the increasing prevalence of pediatric HIV-1 infection, indiscriminate BCG immunization programs should be reconsidered. While infants with asymptomatic HIV-1 infection at risk for tuberculosis should be immunized, BCG immunization should be withheld in those with symptomatic disease.”

Clinicians should be aware of this clinical manifestation that could help diagnose atypical or incomplete cases of the disease.”

Two infants with tuberculid associated with Kawasaki disease.

“The adverse events of BCG vaccination, including local reactions, lymphadenitis, osteomyelitis, tuberculid, and disseminated infection, have been reported. Two infants presented erythema at the inoculation site of BCG after the resolution of Kawasaki disease (KD). They received BCG vaccination 1 week and 6 weeks before the KD onset, respectively. Intravenous immunoglobulin improved the KD activity, however the skin rash of BCG inoculation site extended to the face and extremities days 24 and 10 after the KD onset, respectively. Both bacteriological study and interferon-γ release assay were negative for Mycobacterium tuberculosis infection. These patients were diagnosed as having tuberculid after KD.”

An ulcerated lesion at the BCG vaccination site during the course of Kawasaki disease.

“We describe a bacillus Calmette-Guérin (BCG) granuloma that occurred during the course of Kawasaki disease. A 12-month-old male infant with Kawasaki disease had an erythematous indurated plaque with prominent necrotic ulceration at the BCG vaccination site on the left upper arm. Histologic study showed a granulomatous reaction consisting of epithelioid histiocytes, lymphoid cells, and Langhans-type giant cells. No evidence of mycobacterial infection was obtained. The lesion healed completely within 2 weeks without administration of antituberculous agents. We believe that the granulomatous reaction occurred as a result of hypersensitivity to proteins in the BCG vaccine, which appeared after the onset of Kawasaki disease.”
