Booster dose of BCG vaccine may help fight TB

One of the failures in treating tuberculosis relates to the need for strict compliance by a patient (The battle against TB is not over; March 24).

TB treatment can last for months and the patient has to report to a clinic daily to take his medicine under supervision.

Patients may also develop a tolerance to the prescribed medicine, which means a new regimen of drugs has to be used and treatment started all over again.

Under our primary vaccination schedule, only one dose of the BCG vaccine, which guards against TB, is provided at birth.

Perhaps a booster dose in adulthood would be helpful, given the re-emergence of the disease.
