TB is a Pandemic It is the leading infectious cause of death worldwide. The World Health Organization estimates that 1.8 billion people—close to one quarter of the world’s population—are infected with Mycobacterium tuberculosis (M.
At what age is TB vaccine given?
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.
Is the TB vaccine effective?
Because the bacteria in the vaccine is weak, it triggers the immune system to protect against the disease. This gives good immunity to people who receive it without actually causing the disease. The vaccine is 70 to 80% effective against the most severe forms of TB, such as TB meningitis in children.
Is the TB vaccine safe?
Is the vaccine safe? In most circumstances the vaccine is safe. As with any vaccination, BCG can result in severe adverse reactions and you should discuss this with the nurse before vaccination.

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.
Is TB vaccine required in USA?
The tuberculosis (TB) vaccine is rarely used in the United States. It is only recommended for children living with someone who is actively infected with TB who either (1) cannot take antibiotics to treat the infection or (2) is infected with a strain of TB that is highly resistant to all antibiotics.
Why is tuberculosis rare in the US?
In the past, another major cause of human tuberculosis was Mycobacterium bovis (M. bovis), the causative agent of tuberculosis in cattle. Humans got infected through drinking raw milk, but with the introduction of milk pasteurization this form of human tuberculosis has become very rare in the United States.
Where is TB most common?
Worldwide, TB is most common in Africa, the West Pacific, and Eastern Europe. These regions are plagued with factors that contribute to the spread of TB, including the presence of limited resources, HIV infection, and multidrug-resistant (MDR) TB.
How common is TB in Canada?
Rate of tuberculosis in Canada In 2017, the rate of active tuberculosis in Canada was 4.9 per 100,000 population. The rate was highest among Canadian-born Indigenous Peoples (21.5 per 100,000 population).
How often do you need TB vaccine?
How long does the vaccine protection last? Studies show that the BCG vaccine protects against serious TB disease for up to 15 years after vaccination.
Why is the TB vaccine not given in the US?
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.
