What Is Tuberculosis (TB)?
9. Are Vaccines Effective?
Vaccinations are generally not recommended in the United States because the prevalence of the disease is still relatively low. Furthermore, the vaccines are not very effective in adults. At-risk children can benefit from the bacillus Calmette-Guerin vaccine.
Children living in or traveling to high-risk countries may benefit from receiving BCG. It doesn’t necessarily guarantee they won’t contract the disease, however, because it doesn’t protect against all strains. There are several potential vaccinations in various stages of development and testing.
