Thousands of infants born in remote northern parts of Kenya in the past six weeks risk contracting tuberculosis (TB) due to a vaccine shortage, with medics warning that the effects could be severe in areas where there is already little access to maternity and vaccination services. In the north-central Isiolo region, for example, stocks of the TB Bacillus Camille Guérin (BCG) vaccine ran out at the main Isiolo District Hospital in early April, leaving hundreds of babies unimmunized.
