Which of the following is false regarding normal reaction following BCG vaccination: (AIIMS Nov 09)
|B||Ulceration with crust|
|C||Heals within 6-12 weeks|
|D||Maximum size of papule is reached at 5 weeks|
Normal Reaction To BCG Vaccine: 2-3 weeks after an intradermal injection of a BCG vaccine, a papule develops at the site of injection. It then increases slowly in size and reaches a diameter of about 4-8 mm in about 5 weeks time. It then subsides or breaks into a shallow ulcer, rarely open, but usually seen covered with a crust. Within 6-12 weeks it heals spontaneously, leaving a permanent, tiny round scar. The scar is of 4-8 mm in diameter.
Complications of BCG vaccine include prolonged severe ulceration at the site of vaccination, suppurative lymphadenitis, osteomyelitis, disseminated BCG infection and death.
