Proposed strategy (Strategy 2)	Newly detected cases of leprosy - MDT + MIP	MDT + MIP vaccination (2 doses in PB patients and 3 doses in MB patients; each dose given at interval of six months). Follow up post MDT for five yr
	Contacts of newly detected cases - MIP + active follow up	1st dose consisting of 2 divided doses on both the upper arms on day zero, followed by repeat single dose after six months. Follow up postvaccination for five yr
Standard comparator (Strategy 1)	Newly detected cases of leprosy - MDT + follow up	Current practice of MDT; follow up post-MDT for five yr
	Contacts of newly detected cases - Active follow up as per Programme guidelines	Active follow up for five yr as per Programme guidelines
