During the first half of the 20th century, it was administered ubiquitously throughout Europe, but is now recommended by the World Health Organization (WHO) to be given once at birth, specifically in tuberculosis-endemic areas. Global estimated tuberculosis (TB) incidence rates, 2011.
Why is there no TB vaccine?
However, BCG is not generally recommended for use in the United States because of the low risk of infection with Mycobacterium tuberculosis, the variable effectiveness of the vaccine against adult pulmonary TB, and the vaccine’s potential interference with tuberculin skin test reactivity.
Why is BCG given in left arm?
The vaccine is given just under the skin (intradermally), usually in the left upper arm. This is the recommended site, so that small scar left after vaccination can be easily found in the future as evidence of previous vaccination.
Does everyone get a scar from BCG?

At what age is BCG vaccine given?
Immunization of infants with Bacille Calmette-Guérin vaccine (BCG) can protect against TB meningitis and other severe forms of TB in children less than five years old. BCG vaccine is not recommended after 12 months of age because the protection provided is variable and less certain.
Can you get BCG vaccine twice?
There are some countries that give repeated doses of BCG vaccine. For example, Turkey gives BCG immunization four times: during infancy at two months after birth, at six to seven years of age (first grade), at eleven to twelve years of age (fifth grade), and sixteen to seventeen years of age (high school) .
What is the first injection given to a newborn baby?

Does TB have a vaccine?
Bacille Calmette-Guérin (BCG) is a vaccine for tuberculosis (TB) disease. This vaccine is not widely used in the United States, but it is often given to infants and small children in other countries where TB is common. BCG does not always protect people from getting TB.
Does BCG vaccine last for life?
The BCG vaccination is thought to protect up to 80% of people against the most severe forms of TB for at least 15 years, perhaps even up to 60 years.
Why is BCG given at birth?
In most tuberculosis (TB) endemic countries, bacillus Calmette Guérin (BCG) is usually given around birth to prevent severe TB in infants. The neonatal immune system is immature. Our hypothesis was that delaying BCG vaccination from birth to 10 weeks of age would enhance the vaccine-induced immune response.
Can you get TB if you’ve had the BCG?
You can still get TB infection or TB disease even if you were vaccinated with BCG. You will need a TB test to see if you have latent TB infection or TB disease.
