The BCG vaccine against tuberculosis helps in preventing leprosy by boosting immunity. It is given at birth in many countries and is also given to contacts of people affected by leprosy in a number of countries. In addition, several organisations and institutions are involved in early trials to test a new vaccine for leprosy. Similar to the MIP vaccine in India, this vaccine is expected to be suitable for post-exposure immunoprophylaxis also.
